| Abstract: | In this study, effect and correlation of alkyl chain length (C8, C10, C12, C14, and C16) and concentration of n-alkyl sulfate acid used as representative Br?nsted acid-combined-surfactant catalysts on dehydration esterification of oleic acid with 1-octanol as typical substrates are researched. CMC of the series surfactant are measured by surface tension method. The results indicate that alkyl chain length as well as concentration of catalyst plays an important role in determining conversion of esterifications. Appropriate chain length surfactant and concentration should be chosen for the combined-surfactant catalyzed reaction. |
