Acetic anhydride reacts violently on contact with water, steam, methanol, ethanol, glycerol and boric acid. Reaction with water is particularly dangerous in presence with mineral acids (e.g., nitric, perchloric, chromic, sulfuric acid) [Chem. Eng. News 25, 3458]. Potentially explosive reactions...
water17O-enriched acetic acid (2.5% in 17O) was synthesized by hydrolysis of acetic anhydride with 17O-enriched water. The reaction was monitored by 17O and 1H NMR spectroscopy. Acetic anhydride, 17O-enriched in both the ether and the carbonyl oxygens, was observed as an intermediate. ...
Thereaction mixture is mixed with water or ice. This may result in theprecipitation of the product that can be separated by filtration. If noprecipitation occurs, the product can be extracted with an organic solvent,such as CH2Cl2, CHCl3, Et2O orEtOAc. The organic phase is washed with an aq...
acooking,and she cooks for us everyday.And my mother sings well. 烹调和她为我们烹调每天。并且我的母亲很好唱歌。[translate] aWe shall use the ARSST to study the reaction between acetic anhydride and water to form acetic acid. 我们将使用ARSST学习反应在乙酸酐和水之间形成乙酸。[translate]...
Cyclodehydration was accomplished by adding acetic anhydride and fused sodium acetate (22.1 ml and 0.02 g, respectively, per mol of water condensed to the reaction solution and heating at 90 [degrees] C for 0.5h). Synthesis and properties of new polymaleimides containing allyl groups Specialists...
In II the velocity constant is lower than in I and decreases linearly with increasing concentration of MEK, but, again, the reaction is pseudomonomolecular for any given initial concentration of acetic anhydride. An equation and a nomogram that relate the velocity constant to the initial ...
