Abstract:
Year by year, the used of plasticizer in the world has been improving, where the raw material that is mostly used comes from petroleum. However, the continuing degradation of petroleum reserve demands the plasticizer industry to find alternative sources. One of alternative sources that can be used is the waste of “Patin” fish oil. The process of making plasticizer from this alternative material is conducted by transesterificating the fish oil with isoprophanol and H-Zeolit catalyst. This experiment is made by using the agitated reactor. The agitation speed is around 175rpm and the temperature is 79-80C. The reaction time is around (4, 5, and 6 hours) with catalyst composition is around (5; 10; 15% of the total weight). The highest conversion resulted is 76, 87%, the reaction time is 6 hours, and the composition of catalyst is 15%. This result of transesterization is tested by using GCMS method. The result show that there is no main ester product found as expected, but it results isopropyl stearat 0,52%.
