Short chain citronellyl esters were synthesized using a new microbial lipase from Rhizopus sp. Direct esterification and transesterification reactions were performed to produce the citronellyl acetate and butyrate in a free-solvent system and with n-hexane in the reaction medium. Direct esterification and transesterification were carried out at 45 degrees C in equimolar concentrations of substrates: acid or ester and alcohol. Citronellyl butyrate was synthesized by direct esterification, with yields of 95-100% after 24 h of reaction time, with or without n-hexane.
