說明
一般描述
乙酸是一種脂肪族有機酸。[1]這是一種易吸濕的腐蝕性液體，有一種類似醋的氣味。[1][2]它可以在錳或鈷鹽存在下氧化乙醛合成。[2]用于乙酸酐、醋酸纖維素和乙酸酯的合成。[2]已有關于它對紙張老化的影響的研究。[3]
應用
Acetic acid (AcOH) can be used as:
A reaction solvent in many organic reactions such as bromination, hydrolysis, solvolysis, reductions, and hydrogenations.
A reagent in the protonolysis of organometallic compounds.
An acetylating agent for the acetylation of electron-rich aromatic compounds.
A catalyst to synthesize di(indolyl)methanes by the condensation reaction of indole and aromatic aldehydes.
A solvent system to prepare 3,4-dihydropyrimidin-2(1H)-one derivative via Biginelli reaction of aromatic aldehydes, 1,3-dicarbonyl compounds, and urea in the presence of a boric acid catalyst.
Acetic acid can also be used in the following:
Manganese(III) acetate/AcOH catalytic system is used in the conversion of alkenes to lactones.
Iron salts/AcOH is used to oxidize 2-methylnaphthalene to 2-methyl-1-naphthol in the presence of H2O2.
