说明

一般描述

乙酸是一种脂肪族有机酸。[1]这是一种易吸湿的腐蚀性液体,有一种类似醋的气味。[1][2]它可以在锰或钴盐存在下氧化乙醛合成。[2]用于乙酸酐、醋酸纤维素和乙酸酯的合成。[2]已有关于它对纸张老化的影响的研究。[3]

应用

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.
