WebSep 3, 2024 · The computational results show that the esterification occurs in the two main steps: the first step is the dehydration reaction of CA to form anhydrides of 5-membered ring and 6-membered ring and the second step is the ring opening reaction with the hydroxyl –OH groups to form the ester products. WebThe phenol is first converted into the ionic compound sodium phenoxide (sodium phenate) by dissolving it in sodium hydroxide solution. The phenoxide ion reacts more rapidly with benzoyl chloride than the original phenol does, but even so you have to shake it with benzoyl chloride for about 15 minutes. Solid phenyl benzoate is formed.
WebThus, acetic anhydride is formed by the reaction of acetic acid and DCC (10). Recently (11) it was reported that DCC reacts also with formic acid to form anhydride, although the anhydride was not isolated. This communication deals with the study of the reaction between Iong-chain fatty acids and DCC and its applica- WebHowever, for dicarboxylic acid anhydrides, such as succinic anhydride, upon reaction with a nucleophile the ring structure of the anhydride opens, forming the acylated product modified to contain a newly formed carboxylate group (Reaction 3.14). Thus, anhydride reagents may be used to both block functional groups and to convert an existing ...
