Indonesia is the world's largest producer of palm oil, 36 million tons in 2016. However, most of <br /> <br /> utilization of crude palm oil is being low with economic value. This production increases continuously <br /> <br /> and it is estimated that it will reach 40 million tons in 2020. That is why it is important to derivatize palm <br /> <br /> oil products to increase its economic value. The main component which palm oil are oleic acid (40%) and <br /> <br /> palmitic acid (45%). Oleic acid or unsaturated fatty acids have the potential to be processed into <br /> <br /> derivative compounds that have a higher economic value by undergoing homometathesis or <br /> <br /> heterometathesis olefin reaction. Olefin metathesis reaction is a catalytic reaction that involves <br /> <br /> exchanging between alkene side groups. Oleic acid (1) was reacted by methanol in an acid condition to <br /> <br /> create methyl oleate in 90% yield. In this research, homometathesis reaction of the ester of oleic acid <br /> <br /> were carried out using Grubbs II catalyst. Homo olefin metathesis reaction produced 9-octadecene and <br /> <br /> dimethyl 9-octadecenoate with 50 % and 47 % of yield respectively. The products were analyzed using <br /> <br /> NMR spectroscopy. Homo reaction product was found in mixed form of its E/Z geometry with E:Z ratio <br /> <br /> at 4:1. <br /> <br /> <br /> (formula)
