ESTERIFICATION OF NYAMPLUNG (Calophyllum inophyllum) OIL WITH IONIC LIQUID CATALYST OF BMIMHSO4 AND MICROWAVES-ASSISTED

Nyamplung (Calophyllum inophyllum) oil contains high free fatty acid (FFA) that is 21.62%. Nyamplung oil can be utilized as raw material for biodiesel production. Microwave is a method of heating that is used intensively to speed up the production process. Ionic liquid has high catalytic activity, high selectivity, can be recycled and environmentally friendly. This study learned about the esterification of nyamplung oil with ionic liquid 1-Butyl-3-methylimidazolium hydrogen sulphate (BMIMHSO4) as catalyst and microwave-assisted. The purpose of this study is to obtain optimum condition of esterification process, with free fatty acid concentration (FFA)
