Abstract

A biocatalytic cascade transforming castor oil into (R,Z)-octadec-9-en-7-ol is presented by combining a lipase catalysed hydrolysis of castor oil into ricinoleic acid followed by a photoenzymatic decarboxylation into (R,Z)-octadec-9-en-7-ol.

All these methods share the intrinsic disadvantage of being reversible reactions thereby necessitating large molar surpluses of the alcohol to attain signi cant conversion into the desired biodiesel fatty acid methyl ester (FAME) (Scheme 1)

Summary

Introduction

Yunjian Ma,a Xizhen Zhang,b Yongru Li,a Peilin Li, a Frank Hollmann *c and Yonghua Wang *a. Conversion of up to 41.7% and overall product concentrations of up to 60 mM, this new bienzymatic and photocatalytic cascade exhibits significant potential for the valorisation of non-edible castor oil. CvFAP opens up an irreversible alternative to the established reversible (trans)esteri cation methods and yields products exhibition an overall higher degree of reduced carbon atoms and therewith a higher speci c caloric value.
