WebChemical Structure of Organic Ester Lubricant Base-Fluids. The chemical structure of the carboxylic ester group is illustrated in Fig. 1, which shows the esterification reaction normally used for production of ester lubricant base-fluids, in which carboxylic acid and organic alcohol raw materials are reacted together with removal of water to form an … WebSaponification is catalyzed by a BASE. The overall reaction mechanism is similar, I think the main difference is the esterification has a proton added to remove the ester and produce an alkene while Saponification has a …

WebMECHANISM OF THE BASE HYDROLYSIS OF ESTERS. Step 1: The hydroxide nucleophiles attacks at the electrophilic C ofthe ester C=O, breaking the π bond and creating the tetrahedral intermediate. Step 2: The intermediate collapses, reforming the C=O. results in the loss of the leaving group the alkoxide, RO-, leading to the carboxylic …
WebClaisen condensation. The Claisen condensation is a carbon–carbon bond forming reaction that occurs between two esters or one ester and another carbonyl compound in the presence of a strong base, resulting in a β-keto ester or a β- diketone.
