Acetic acid, also known as acetic acid, acetic acid, chemical formula CH? COOH, is an organic monobasic acid as a source of inner sour and pungent odor of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid with a freezing point of 16.7 ℃ (62 ℉), solidified as colorless crystals. Although based on the solution of acetic acid in aqueous solution from its ability to be a weak acid, but acid is corrosive, its steam eye and nose irritation effect. [English name] Acetic Acid [other names] acetic acid, acetic acid Indications different concentrations of the product for the treatment of various skin superficial fungal infection, lavage wounds and corns, warts treatment. Acetic acid can be used as etchant. [Drug classification] antiseptic disinfectant - acetic acid ethylene oxidation of ethylene in the catalyst (palladium chloride catalyst is used: PdCl2, copper chloride: CuCl2 and manganese acetate: (CH3COO) 2Mn) in the presence of, and oxygen react generation. This reaction can be considered as the first ethylene oxide into acetaldehyde, acetaldehyde oxidation through the legal system. Butane oxidation of butane oxidation, also known as direct oxidation of acetic acid manufacturer, which is the main raw material used butane acetic acid production, a method prepared by air oxidation of acetic acid is the main acid synthesis. 2CH3CH2CH2CH3 + 5O2 = 4CH3COOH + 2H2O Topsoe method (synthesis gas method) Low Pressure Methanol carbonylation of methanol, co is obtained from natural gas or water gas, methanol is an important chemical raw material supply and its price fluctuations. Topsoe law to a single natural gas or coal as raw materials. The first step: synthesis gas catalyst to generate methanol and dimethyl ether; the second part: methanol and dimethyl ether (both without purification) and co carbonylation to acetic acid. Also called two-step process. Acetic procurement, Zhengzhou Longda Chemical, Ring Road glacial acetic acid provided by the Zhengzhou Longda Chemical Products Co., Ltd.
