Acetic acid Acetic acid Acetic acid , systematically named ethanoic acid , is a colourless liquid organic compound with the chemical formula CHCOOH (also written as CHCOH or CHO). When undiluted, it is sometimes called "glacial acetic acid". Vinegar is no less than 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water. Acetic acid has a distinctive sour taste and pungent smell. In addition to household vinegar, it is mainly produced as a precursor to polyvinyl acetate and cellulose acetate. It is classified as a weak acid since it only partially dissociates in solution, but
Benzilic acid is regulated by the Chemical Weapons Convention. It is also monitored by law enforcement agencies of many countries, because of its use in the manufacture in hallucinogenic drugs. Benzilic acid Benzilic acid is an organic compound with formula or ()(HO)C(COOH). It is a white crystalline aromatic acid, soluble in many primary alcohols. Benzilic acid can be prepared by heating mixture of benzil, ethanol and potassium hydroxide. Another preparation, performed by Liebig in 1838, is the dimerization of benzaldehyde, to benzil, which is transformed to the product by the benzilic acid rearrangement reaction. Benzilic acid is used in the manufacture of
