Synthesis Biolubricant By Esterification Of Castor Oil (Jatropha Curcas L-Oil) With Chlorate Acid Catalyst

Biolubricant is made by reacting vegetable oil with alcohol with the help of strong acid or strong base catalyst in the esterification process. The goal of this research is to know the flash point of bio-lubricant, and know its characteristics. This research is done by reacting Jatropha oil and methanol reactant with perchloric acid with a variety of reactant mol and variety concentration of perchloric acid as a catalyst with esterification time of 7 hours, after that it will be purified by a various method to get the desired result. Results in this research have the highest flash point on 26 oC and lowest on 242 oC; highest viscosity on 217 cP and lowest on 130, 5 cP at 40 oC. At other temperature, the best viscosity is 184,5 cP at 40 oC and 27,45 cP at 100 oC. Average pour point from this bio-lubricant is -18,8 oC. Almost chemistry compound of Biolubricant contains fatty acid 9,12-Octadecadienoic acid (Z, Z) with methanol resulting monoester compound 9-Octadecenoic acid (Z)-, 2-hydroxy-1-(hydroxymethyl) ethyl ester.
