Electronic structure of metals and alloysMagnetic propertiesThe hydrolysis of acetic anhydride in the presence of water is an exothermic reaction that produces acetic acid. Most of the research has focused on low ratios of acetic anhydride to water. The major concern in the industry is the ...
The rate of hydrolysis of acetic anhydride at 25 掳C. in water (I), in solutions of methyl ethyl ketone (MEK) in water (II), and in solutions of water in MEK (III) have been studied. In I the observation of previous investigators that the velocity constant varies linearly with the ...

4.7.3.2 Preparation and Elaboration of α-Acyloxy Sulfides When acetic anhydride is employed in the Pummerer reaction, reflux temperatures are generally required. However, at elevated temperatures α-acetoxy sulfides are labile and if a β-hydrogen is present elimination of acetic acid and formation ...
