Bitter Melon
''Momordica charantia'' (commonly called bitter melon; Goya; bitter apple; bitter gourd; bitter squash; balsam-pear; with many more names listed below) is a tropical and subtropical vine of the family Cucurbitaceae, widely grown in Asia, Africa, and the Caribbean for its edible fruit. Its many varieties differ substantially in the shape and bitterness of the fruit. Bitter melon originated in Africa where it was a dry-season staple food of ǃKung hunter-gatherers. Wild or semi-domesticated variants spread across Asia in prehistory, and it was likely fully domesticated in Southeast Asia. It is widely used in the cuisines of East Asia, South Asia, and Southeast Asia. Alternative names Bitter melon has many names in other languages, which have sometimes entered English as loanwords. Following are a few: Description This herbaceous, tendril-bearing vine grows up to in length. It bears simple, alternate leaves across, with three to seven deeply separated lobes. Each ...

Butanol
Butanol (also called butyl alcohol) is a four-carbon alcohol with a formula of C4 H9 O H, which occurs in five isomeric structures (four structural isomers), from a straight-chain primary alcohol to a branched-chain tertiary alcohol; all are a butyl or isobutyl group linked to a hydroxyl group (sometimes represented as BuOH, ''n''-BuOH, ''i''-BuOH, and ''t''-BuOH). These are ''n''-butanol, 2 stereoisomers of sec-butanol, isobutanol and ''tert''-butanol. Butanol is primarily used as a solvent and as an intermediate in chemical synthesis, and may be used as a fuel. Biologically produced butanol is called biobutanol, which may be ''n''-butanol or isobutanol. Isomers The unmodified term ''butanol'' usually refers to the straight chain isomer with the alcohol functional group at the terminal carbon, which is also known as ''n''-butanol or 1-butanol. The straight chain isomer with the alcohol at an internal carbon is ''sec''-butanol or 2-butanol. The branched isomer with the a ...

Standard Chinese
Standard Chinese ()—in linguistics Standard Northern Mandarin or Standard Beijing Mandarin, in common speech simply Mandarin, better qualified as Standard Mandarin, Modern Standard Mandarin or Standard Mandarin Chinese—is a modern Standard language, standardized form of Mandarin Chinese that was first developed during the Republic of China (1912–1949), Republican Era (1912‒1949). It is designated as the official language of Languages of China, mainland China and a major language in the United Nations languages, United Nations, Languages of Singapore, Singapore, and Languages of Taiwan, Taiwan. It is largely based on the Beijing dialect. Standard Chinese is a pluricentric language with local standards in mainland China, Taiwan and Singapore that mainly differ in their lexicon. Hong Kong written Chinese, used for formal written communication in Hong Kong and Macau, is a form of Standard Chinese that is read aloud with the Cantonese reading of characters.

Ethyl Acetate
Ethyl acetate ( systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula , simplified to . This colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and in the decaffeination process of tea and coffee. Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent. Production and synthesis Ethyl acetate was first synthesized by the Count de Lauraguais in 1759 by distilling a mixture of ethanol and acetic acid. In 2004, an estimated 1.3 million tonnes were produced worldwide. The combined annual production in 1985 of Japan, North America, and Europe was about 400,000 tonnes. The global ethyl acetate market was valued at $3.3 billion in 2018. Ethyl acetate is synthesized in industry mainly via the classic Fischer esterification reaction of ethanol and acetic acid. This mixture converts to the ester in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Methanol
Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical and the simplest aliphatic alcohol, with the formula C H3 O H (a methyl group linked to a hydroxyl group, often abbreviated as MeOH). It is a light, volatile, colourless, flammable liquid with a distinctive alcoholic odour similar to that of ethanol (potable alcohol). A polar solvent, methanol acquired the name wood alcohol because it was once produced chiefly by the destructive distillation of wood. Today, methanol is mainly produced industrially by hydrogenation of carbon monoxide. Methanol consists of a methyl group linked to a polar hydroxyl group. With more than 20 million tons produced annually, it is used as a precursor to other commodity chemicals, including formaldehyde, acetic acid, methyl tert-butyl ether, methyl benzoate, anisole, peroxyacids, as well as a host of more specialised chemicals. Occurrence Small amounts of methanol are present in normal, healthy hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
