Thermomyces lanuginosus Lipase-Catalyzed Esterification of 9,10-Dihydroxystearic Acid and Monohydric Alcohol

Thermomyces lanuginosus Lipase-Catalyzed Esterification of 9,10-Dihydroxystearic Acid and Monohydric Alcohol

An enzymatic method has been developed for the preparation of dihydroxystearic acid ester in high conversion (∼90%) by esterification of 9,10-dihydroxystearic acid and 1-octanol at moderate temperature (50 °C) using immobilized lipase from Thermomyces lanuginosus (Lipozyme TL IM) as biocatalyst. The...

Zusammenfassung:An enzymatic method has been developed for the preparation of dihydroxystearic acid ester in high conversion (∼90%) by esterification of 9,10-dihydroxystearic acid and 1-octanol at moderate temperature (50 °C) using immobilized lipase from Thermomyces lanuginosus (Lipozyme TL IM) as biocatalyst. The effects of enzyme dosage, reaction temperature, reaction time and reusability of the enzyme in esterification were studied.
