REMILLION, BONG CARLO N. College of Arts and Sciences, University of the Philippines, Los Balms. April 2010. Synthesis of Anacardyl Acetate using Anacardic Acid from Cashew (Anacardium occidentale L.) Nut Shell Liquid.

Natural cashew nut shell liquid (CNSL) was extracted from cashew nut shells using mechanical expulsion. Using this process, a dark brown, viscous liquid was obtained. The thin layer chromatography (TLC) profile of natural CNSL showed three spots corresponding to cardanol, anacardic acid and cardol.

Anacardic acid was isolated from natural CNSL by precipitation and liquid-liquid extraction producing crude anacardic acid, a dark red orange, viscous liquid and purified using vacuum liquid chromatography. The structure of anacardic acid was verified using infrared and nuclear magnetic resonance (NMR) spectroscopy.

The ester anacardyl acetate was synthesized from crude anacardic acid and acetyl chloride. The product was purified by vacuum liquid chromatography. The conversion of anacardic acid to anacardyl acetate was verified by infrared and nuclear magnetic spectroscopy.
