چکیده
In this research we used Heavy Propylene Tetramer (HPT) and A1C13 —BF3 (Lewis acids) as catalyst and ethanol, n-propanol and n-butanol as co-catalyst. Using Lewis acids as catalyst, the HPTs form molecules with higher molecular weight. Since the raw materials of the reaction are by products of other reactions, are not pure and contain various compounds with different M.W and also different chemical and physical properties. This fact affects catalyst weight ratio which must be applied for a better result. The effect of different catalysts and co-catalysts on yielded lubricant and reaction yield is investigated. The results show that using alcohol with higher M.W as co- catalyst, increases reaction yield and iodine number, and also a better lubricant can be obtained. Also, A1C13 seems to be a better catalyst in laboratory scale research comparing to BF3.
