acetic anhydride- a compound that is needed in order to refine opium into heroin anhydride- a compound formed from one or more other compounds in a reaction resulting in removal of water Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Farlex Inc. ...
(acetic acid andacetic anhydride). The addition of catalysts (such as NBS, DMAP, pyridine, etc.) could accelerate the reaction and improve the DS of acetylation, which usually occurred on hydroxyl oxygen and amino nitrogen (Yuan et al., 2005). Many studies have shown that the acetylation ...
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 ...
When heated with water, acetic anhydride forms acetic acid. In industry, acetic anhydride is obtained by such methods as the catalytic oxidation of acetaldehyde in the presence of the acetates cobalt and copper and the reaction of acetic acid with ketene. The compound is mainly used in ...
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 ...
