一般描述
醋酸酐是一种有机溶剂溶于水后，其可经过溶剂分解得到乙酸。它被广泛用于各种醇的乙酰化。Wacher法（起始试剂＝烯酮）和Knapsack法（起始试剂＝乙醛）已报到可用于工业上制备乙酸酐。
应用
醋酸酐已作为反应组分之一，用于制备：
- 2-乙酰氨基-5-氨基苯磺酸
- 3,3′-双(磺酸根基)-4,4′-双(氯乙酰氨基)偶氮苯(BSBCA)
- 10-乙酸基-9-硝基硬脂酸，烯丙酯
- 9-硝基油酸

This protocol describes a procedure for the synthesis of 3,3'-bis(sulfonato)-4,4'-bis(chloroacetamido)azobenzene (BSBCA), a water-soluble, thiol-reactive, photo-switchable cross-linker. In addition, a protocol is outlined for installing the cross-linker in an intramolecular fashion onto proteins bearing two surface-exposed Cys residues. BSBCA is designed

Nitrated fatty acids are the product of nitrogen dioxide reaction with unsaturated fatty acids. The discovery of peroxynitrite and peroxidase-induced nitration of biomolecules led to the initial reports of endogenous nitrated fatty acids. These species increase during ischemia/reperfusion, but concentrations

In this study acetyloxypropylene dimethacrylate was synthesized and proposed as an alternative monomer for triethyleneglycol dimethacrylate (TEGDMA) in dental mixtures. The monomer was prepared by the reaction of glycerol dimethacrylate with acetic anhydride. The exchange reaction was carried out in
