Utilization of fatty acid from papaya seed waste oil (carica papaya l) as a raw material in the making of epoxy compound

Abstract

Epoxy is a compound that is produced from the reaction between double bond inside the fatty acid and active oxygen. This compound could be applied as a stabilizer, plasticizer on PVC (Polyvinyl Chloride) and could be used an antioxidant in processing natural rubber, surfactant, anti-corrosive-additive agent on lubricant, and as raw material for pesticide. The raw material in this study was papaya seed oil. The aim of this research to get the effect of catalyst concentration, amount of H2O2 (ml) and stirring rate (rpm) on the characteristics of epoxy compounds. In this study, fatty acid, which was contained in raw material, was reacted to hexane, glacial acetic acid, H2O2 with the variation of 40ml, 50ml, 60ml, and 70ml, sulfuric acid as a catalyst with variation, stirring velocity with variation of 400 rpm, 500 rpm and 600 rpm for 180 minutes. The result of this study showed that the best epoxy compound result was acquired at 2.5% of catalyst concentration, 70ml H2O2 and 600 rpm of stirring speed, where the oxirane oxygen value was reached 3.52, iodine number was 10,4058 and oxygen conversion was 73, 76471%.
