Tricresyl Phosphate
Tricresyl phosphate (TCP), is a mixture of three isomeric organophosphate compounds most notably used as a flame retardant. Other uses include as a plasticizer in manufacturing for lacquers and varnishes and vinyl plastics and as an antiwear additive in lubricants. Pure tricresyl phosphate is a colourless, viscous liquid, although commercial samples are typically yellow. It is virtually insoluble in water, but easily soluble in organic solvents like toluene, hexane, and diethyl ether among others. It was synthesized by Alexander William Williamson, Alexander Williamson in 1854 upon reacting phosphorus pentachloride with cresol (a mixture of para-, ortho-, and meta- isomers of methylphenol), though today's manufacturers can prepare TCP by mixing cresol with phosphoryl chloride, phosphorus oxychloride or phosphoric acid as well. TCP, especially the all-ortho isomer, is the causative agent in a number of acute poisonings. Its chronic toxicity is also of concern. The ortho-isomer is rar ...

Organophosphate
In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure , a central phosphate molecule with alkyl or aromatic substituents. They can be considered as esters of phosphoric acid. Organophosphates are best known for their use as pesticides. Like most functional groups, organophosphates occur in a diverse range of forms, with important examples including key biomolecules such as DNA, RNA and ATP, as well as many insecticides, herbicides, nerve agents and flame retardants. OPEs have been widely used in various products as flame retardants, plasticizers, and performance additives to engine oil. The low cost of production and compatibility to diverse polymers made OPEs to be widely used in industry including textile, furniture, electronics as plasticizers and flame retardants. These compounds are added to the final product physically rather than by chemical bond. Due to this, OPEs leak in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gingelly Oil
Sesame oil is an edible vegetable oil derived from sesame seeds. The oil is one of the earliest-known crop-based oils. Worldwide mass modern production is limited due to the inefficient manual harvesting process required to extract the oil. Oil made from raw seeds, which may or may not be cold-pressed, is used as a cooking oil. Oil made from toasted seeds is used for its distinctive nutty aroma and taste, although it may be unsuitable for frying, which makes it taste burnt and bitter. Manufacture Manufacturing process Sesame seeds are protected by a capsule which bursts only when the seeds are completely ripe, a process called dehiscence. The dehiscence time tends to vary, so farmers cut plants by hand and place them together in an upright position to continue ripening, until all the capsules have opened. Tanzania remains the largest producer of sesame oil and also dominates the global consumption of this product. The African and Asian regions constitute the fastest-dev ...

Eckernförde
Eckernförde (; , sometimes also ; , sometimes also ) is a city located in the of Rendsburg-Eckernförde, Schleswig-Holstein, northern Germany. Situated on the coast of the Baltic Sea, approximately 30 km north-west of Kiel, it has a population of about 23,000. Eckernförde is a popular tourist destination. Name The name of Eckernförde is of mixed origin, but derived from the name of a Danish castle formerly located near the current town, which is also reflected in the name of the town district of ''Borby.'' This fortification is listed in the 13th-century Liber Census Daniæ (Danish Census Book) as ''Ykærnæburgh.''Politikens Nudansk Ordbog, 1994 edition, entry "Eckernförde" In 1441, the town used an official seal listing its name as ''Eherneborgh''.Poul Bredo Grandjean (1953), ''Slesvigske Købstæders og Herreders Segl indtil 1660'', J.H.

Oil Soldiers
Oil soldiers (German ''Ölsoldaten'') is the name given to soldiers of the Swiss Army poisoned by accident in 1940, when they were served ''Käseschnitten'' (fried bread with cheese) in which mineral oil mixed with tricresyl phosphate, intended as a coolant for machine guns, was mistakenly used for the preparation of the dish. Course of events On July 29, 1940, peanut oil, used in the preparation of food for a company (Mitr Kp IV/52) in Ramiswil, canton of Solothurn, was mixed with machine gun cooling oil by mistake and used to make a cheese dish (''Käseschnitten''). That happened because, after a drill, the coolant was stored in cooking oil cans that weren't marked properly, and the oil was indistinguishable from cooking oil by taste or appearance. That led to 74 soldiers and 10 to 12 civilians suffering from tricresyl phosphate poisoning, causing paralysis of the legs which in some cases was grave and irreversible. There were civilians, including children, among the victims o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hippocrates
Hippocrates of Kos (; ; ), also known as Hippocrates II, was a Greek physician and philosopher of the Classical Greece, classical period who is considered one of the most outstanding figures in the history of medicine. He is traditionally referred to as the "Father of Medicine" in recognition of his lasting contributions to the field, such as the use of prognosis and clinical observation, the systematic categorization of diseases, and the (however misguided) formulation of Humorism, humoral theory. His studies set out the basic ideas of modern-day specialties, including surgery, urology, neurology, acute medicine and Orthopedic surgery, orthopedics. The Hippocratic school of medicine revolutionized ancient Greek medicine, establishing it as a discipline distinct from other fields with which it had traditionally been associated (theurgy and philosophy), thus establishing medicine as a profession. However, the achievements of the writers of the Hippocratic Corpus, the practitioners ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parsley
Parsley, or garden parsley (''Petroselinum crispum''), is a species of flowering plant in the family Apiaceae that is native to Greece, Morocco and the former Yugoslavia. It has been introduced and naturalisation (biology), naturalized in Europe and elsewhere in the world with suitable climates, and is widely cultivated as an herb and a vegetable. It is believed to have been originally grown in Sardinia, and was cultivated in around the 3rd century BC. Linnaeus stated its wild habitat to be Sardinia, whence it was brought to England and apparently first cultivated in Britain in 1548, though literary evidence suggests parsley was used in England in the Middle Ages as early as the Anglo-Saxon period. Parsley is widely used in European cuisine, European, Middle Eastern cuisine, Middle Eastern, and American cuisine. Curly-leaf parsley is often used as a garnish (food), garnish.

Phenylpropanoid
The phenylpropanoids are a diverse family of organic compounds that are biosynthesized by plants from the amino acids phenylalanine and tyrosine in the shikimic acid pathway. Their name is derived from the six-carbon, aromatic phenyl group and the three-carbon propene tail of coumaric acid, which is the central intermediate in phenylpropanoid biosynthesis. From 4-Coumaroyl-CoA, 4-coumaroyl-CoA emanates the biosynthesis of myriad natural products including Monolignol, lignols (precursors to lignin and lignocellulose), flavonoids, isoflavonoids, coumarins, aurones, stilbenes, catechin, and phenylpropanoids. The coumaroyl component is produced from cinnamic acid. Phenylpropanoids are found throughout the plant kingdom, where they serve as essential components of a number of structural polymers, provide protection from ultraviolet light, defend against herbivores and pathogens, and also mediate plant-pollinator interactions as floral pigments and scent compounds. Hydroxycinnamic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apiol
Apiol, also known as liquid apiol or green oil of parsley is the extracted oleoresin of parsley, rather than the distilled oil. Due to its similarity to the term apiole, care should be taken to avoid confusion. Apiol is an irritant and, in high doses, it can cause liver and kidney damage. Cases of death due to attempted abortion using apiol have been reported. Hippocrates wrote about parsley as a herb to cause an abortion. Plants containing apiole were used by women in the Middle Ages to terminate pregnancies. Its use was widespread in the US, often as ergoapiol or apergol, until a highly toxic adulterated product containing apiol and tri-ortho-cresyl phosphate (also famous as the adulterant added to Jamaica ginger) was introduced on the American market. Now that safer methods of abortion are available, apiol is almost forgotten. References Further reading * * Resins Abortifacients {{Medicinal-plant-stub ...

Eighteenth Amendment To The United States Constitution
The Eighteenth Amendment (Amendment XVIII) to the United States Constitution established the prohibition of alcohol in the United States. The amendment was proposed by Congress on December 18, 1917, and ratified by the requisite number of states on January 16, 1919. The Eighteenth Amendment was repealed by the Twenty-first Amendment on December 5, 1933, making it the only constitutional amendment in American history to be repealed. The Eighteenth Amendment was the product of decades of efforts by the temperance movement, which held that a ban on the sale of alcohol would ameliorate poverty and other societal problems. The Eighteenth Amendment declared the production, transport and sale of intoxicating liquors illegal, although it did not outlaw the actual consumption of alcohol. Shortly after the amendment was ratified, Congress passed the Volstead Act to provide for the federal enforcement of Prohibition. The Volstead Act declared that liquor, wine and beer qualified as in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jamaica Ginger
Jamaica ginger extract, known in the United States by the slang name Jake, was a late 19th-century patent medicine that provided a convenient way to obtain alcohol during the era of Prohibition in the United States, Prohibition, since it contained approximately 70% to 80% ethanol by weight. In the 1930s, a large number of users of Jamaica ginger were afflicted with a paralysis of the hands and feet that quickly became known as Jamaica ginger paralysis or jake paralysis. Composition While Jamaica ginger was essentially an infusion of ginger, the US government required solids to be added with the intention of making it less palatable as a way to obtain alcohol legally. The solids expected to be added were particles of ginger root, which made the "medicine" unpalatable. Manufacturers sought solids which impaired the taste less; Tricresyl phosphate#Health calamities from TCP, tricresyl phosphate was used, which the producers later found to be a potent neurotoxin; adulterated Jake ...
