The use of acetic acid in alchemy extends into the 3rd century BC, when the Greek philosopher Theophrastus described how vinegar acted on metals to produce pigments useful in art, including white lead (lead carbonate) and verdigris, a green mixture of copper salts including copper(II) acetate. Acidity regulators are indicated by their E number, such as E260 (acetic acid), or simply listed as "food acid". E304 Fatty acid esters of ascorbic acid (i) Ascorbyl palmitate (ii) E938 Argon [Packaging gas] Other processes are methyl formate isomerization, conversion of syngas to acetic acid, and gas phase oxidation of ethylene and ethanol. E290 Carbon dioxide [Acidity regulator] Acetic acid /əˈsiːtɪk/, systematically named ethanoic acid /ˌɛθəˈnoʊɪk/, is a colourless liquid organic compound with the chemical formula CH3COOH (also written as CH3CO2H, C2H4O2, or HC2H3O2). E codes are codes sometimes found on food labels in the European Union (GB, France, Germany, Spain, Italy, Portugal, etc.) The E indicates that it is a "European Union approved" food additive. 2.10.1—2 Definitions E518 Magnesium sulphate, Epsom salts [Acidity regulator] [Firming Agent] regulator] In more recent times, chemical company Showa Denko, which opened an ethylene oxidation plant in Ōita, Japan, in 1997, commercialised a cheaper single-stage conversion of ethylene to acetic acid.
