Vanillin is mixed with acetic anhydride in the present of {eq}\rm NaOH {/eq} to form an ester. Draw out the mechanism of the reaction. Structure of Vanillin: Vanillin is an organic compound that contains a benzene ring with three substituents: m...
The experimental results are discussed in relation to the probable equilibria involved. Evidence for an increased acidity function is presented, and a reaction mechanism postulated. Certain amides cannot be titrated in acetic anhydride. These are discussed with regard to configuration. 展开 关键词:...
