Green Synthesis of Isopropyl Ricinoleate

Journal of Oleo Science, 2013
Increased environmental awareness is slowly driving the industry to develop alternatives to chemical routes for synthesis. Lipase catalysed synthesis is one such alternative route that is environmentally more acceptable. In this study, immobilized Candida antarctica lipase (Lipozyme 435) was used for the esterification of ricinoleic acid and isopropyl ...
