Abstract

The needs of having a substitute for petroleum based lubricant are being studied by researchers since the last decades. Vegetable oil which is known to be biodegradable, renewable and have the similar properties of lubrication as petroleum based oil is seen to be a candidate for the substitution. However, the high content of unsaturated fatty acids in vegetable oils causes the oil to be less cooperative in stabilizing oxidation. The purpose of this paper is to discuss the effect of zinc dialkyldithiophosphate (ZDDP) addition as antioxidation agent in commercialized corn oil process as a barrier to commercialized corn oil. The introduction of ZDDP into the corn oil could resolve the oxidation problem since ZDDP is an effective antioxidant. The capability of ZDDP exhibits both primary and secondary antioxidant is desirable in biolubricant oil in order to suppress the oxidation process.
