Camille Dreyfus (chemist)
Camille Edouard Dreyfus (November 11, 1878 – September 27, 1956) was a Swiss chemist. He and his brother Henri Dreyfus invented Celanese, an acetate yarn. He founded The Camille and Henry Dreyfus Foundation in honour of his brother. Early years Camille Dreyfus was born into a Jewish family from Basel, Switzerland in 1878. His parents were Abraham and Henrietta (née Wahl) Dreyfus. His brother Henri Dreyfus was born four years later, in 1882. The brothers both went to school in Basel and then studied at the University of Paris, Sorbonne, Paris. Their father was involved with a chemical factory. In 1901 Dreyfus earned a PhD from the University of Basel with the highest honors. The brothers began experimenting in a small laboratory in a corner of the garden of their father's house in Basel. Their first achievement was to develop synthetic indigo dyes. In 1908 the two brothers turned to developing cellulose acetate, including scientific investigation of the properties of the co ...

1211 Avenue Of The Americas
1211 Avenue of the Americas, also known as the News Corp. Building, is an International Style skyscraper on Sixth Avenue in the Midtown Manhattan neighborhood of New York City. Formerly called the Celanese Building, it was completed in 1973 as part of the later Rockefeller Center expansion (1960s–1970s) dubbed the Construction of Rockefeller Center#1960s and 1970s, "XYZ Buildings". Celanese, its primary tenant, later moved to Dallas, Texas. The building is owned by Ivanhoé Cambridge . The structure has a simple slab-like shape devoid of any decoration, its prosaic façade consisting of vertical alternating limestone and glass stripes. The façade stone piers are supernumerary; there are twice as many of them as structurally necessary. The glass bands are contiguous and offer no indication of floor levels. These features ably create the visual lack of scale, so the tower does not look overly bulky. Background The building was part of the later Rockefeller Center expansio ...

Cellulose Acetate
In biochemistry, cellulose acetate refers to any acetate ester of cellulose, usually cellulose diacetate. It was first prepared in 1865. A bioplastic, cellulose acetate is used as a film base in photography, as a component in some coatings, and as a frame material for eyeglasses; it is also used as a synthetic fiber in the manufacture of Cigarette filter, cigarette filters and Playing card, playing cards. In cellulose acetate film, photographic film, cellulose acetate film replaced nitrate film in the 1950s, being far less flammable and cheaper to produce. Water-soluble cellulose acetate (WSCA) has been used as a Prebiotic (nutrition), dietary fiber (prebiotic), in relation with weight loss and Akkermansia muciniphila. History In 1865, French chemist Paul Schützenberger discovered that cellulose reacts with acetic anhydride to form cellulose acetate. The German chemists Arthur Eichengrün and Theodore Becker invented the first soluble forms of cellulose acetate in 1903. In 190 ...

Ocotlán, Jalisco
Ocotlán is a city and municipality in Jalisco, Mexico. Its industry includes furniture production. Is the seat of the Región Ciénega. Etymology ''Ocotlán'' means "near the pines" or "place of the ocote (pines)". Ocote is from Nahuatl ''ocōtl'', ''Pinus montezumae'', a species of pine. History Ocotlán was founded in 1530. Two main cathedrals line the plaza. One is the church named La Purisima ("The Most Pure"), which is one of the oldest buildings in Jalisco. The altar is dipped in gold. The other cathedral, more recent than La Purisima, was built in the late 1800s and dedicated to Nuestro Señor de Misericordia (Our Merciful Lord), which honors a vision of Christ seen after an extremely destructive earthquake. The current municipal president is Lic. Josué Avila, from the MORENA party in Mexico. Appearance of Christ On October 2, 1847 at approximately 0730, a large and powerful earthquake destroyed most of the city, including the original church. The following day, a S ...

Acetic Acid
Acetic acid , systematically named ethanoic acid , is an acidic, colourless liquid and organic compound with the chemical formula (also written as , , or ). Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. Historically, vinegar was produced from the third century BC and was likely the first acid to be produced in large quantities. Acetic acid is the second simplest carboxylic acid (after formic acid). It is an important Reagent, chemical reagent and industrial chemical across various fields, used primarily in the production of cellulose acetate for photographic film, polyvinyl acetate for wood Adhesive, glue, and synthetic fibres and fabrics. In households, diluted acetic acid is often used in descaling agents. In the food industry, acetic acid is controlled by the E number, food additive code E260 as an acidity regulator and as a condiment. In biochemistry, the acetyl group, derived from acetic acid, is funda ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vinyl Acetate Monomer
Vinyl acetate is an organic compound with the formula CH3CO2CH=CH2. This colorless liquid is the precursor to polyvinyl acetate, ethylene-vinyl acetate copolymers, polyvinyl alcohol, and other important industrial polymers. Production The worldwide production capacity of vinyl acetate was estimated at 6,969,000 tonnes/year in 2007, with most capacity concentrated in the United States (1,585,000 all in Texas), China (1,261,000), Japan (725,000) and Taiwan (650,000). The average list price for 2008 was US$1600/tonne. Celanese is the largest producer (ca 25% of the worldwide capacity), while other significant producers include China Petrochemical Corporation (7%), Chang Chun Group (6%), and LyondellBasell (5%). Vinyl acetate is mainly (80%) polymerized, and the resulting polymer is hydrolyzed to give polyvinvyl alcohol. Preparation Vinyl acetate is the acetate ester of vinyl alcohol. Since vinyl alcohol is highly unstable (with respect to acetaldehyde), the preparation of vinyl a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurong Island
Jurong Island is an island located to the southwest of the main island of Singapore. It was formed from the amalgamation of seven offshore islands, the islands of Pulau Ayer Chawan, Pulau Ayer Merbau, Pulau Merlimau, Pulau Pesek, Pulau Pesek Kechil (also called Terumbu Pesek), Pulau Sakra (which was a previous merger of Pulau Sakra and Pulau Bakau), Pulau Seraya, Pulau Meskol, Pulau Mesemut Laut, Pulau Mesemut Darat and Anak Pulau. This was done through Land reclamation in Singapore, Singapore's land reclamation efforts. Land reclamation on Jurong Island was completed on 25 September 2009, 20 years earlier than scheduled. Pulau Buaya was joined to Jurong Island via reclamation in 2010. Jurong Island forms a land area of about from an initial area of less than , and is the largest of Singapore's outlying islands. History The island was previously a stop on a maritime trade route. Jurong Island used to be a maze of island hideouts frequented by raiding pirates. Later in the ...

Silk
Silk is a natural fiber, natural protein fiber, some forms of which can be weaving, woven into textiles. The protein fiber of silk is composed mainly of fibroin and is most commonly produced by certain insect larvae to form cocoon (silk), cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular Prism (optics), prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Harvested silk is produced by several insects; but, generally, only the silk of various moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing holometabolism, complete metamorphosis, but some insects, such as webspinners and Gr ...
