Other esters to take into consideration are those formed from acetic acid and higher alcohols (chains containing more than two carbon atoms). These include isoamyl acetate and 2-phenylethyl acetate, both of which have very pleasant aromas (banana and rose). As with ethyl esters, their concentrati...
A liquid phase containing the carboxylic acid component, e.g. a fatty acid mixture, flows down the column reactor from one esterification tray to the next downward one against an upflowing alcohol vapour stream, e.g. methanol vapour. Relatively dry alcohol vapour is injected (21) into the ...

Hydrazine and its mono- and di-substituted derivatives all undergo addition to acetylene mono- and di-carboxylic acid esters. Hydrazine hydrate and diethyl acetylenedicarboxylate formed ethyl 5-oxopyrazoline-3-carboxylate (344) 〈1893CB1719〉. Phenylhydrazine and DMAD formed a 1 :...
The meaning of ORTHO ESTER is an ester of an ortho acid; especially : an ester RC(OR')3 (as orthoformic ester) of an ortho-carboxylic acid.
Aromatic and aliphatic aldoximes could be efficiently converted into the corresponding carboxylic acid esters by treatment aldoximes with an alcoholic solution of 30% hydrogen peroxide in the presence of catalytic amounts of polystyrene-bound phenylseleninic acid. 在30%双氧水和醇组成体系中,聚合物负载的...
