Lipase‐catalyzed alcoholysis of crambe oil and camelina oil for the preparation of long‐chain esters
Abstract Crambe oil and camelina oil were transesterified with oleyl alcohol, the alcohols derived from crambe and camelina oils, n ‐octanol or isopropanol using Novozym 435 (immobilized lipase B from Candida antarctica ), Lipozyme IM (immobilized lipase from Rhizomucor miehei ), and papaya ( Carica...
