Abstract
It has conducted research on the use of chitosan, and N-alkyl chitosan (N-methyl chitosan, N-isopropyl chitosan) as a heterogeneous base catalyst in the transesterification reaction of used cooking oil. Chitosan, N-methyl chitosan, and N-isopropyl chitosan synthesized by reacting chitosan with formaldehyde and acetone successively forming Schiff bases were then reduced using NaBH4. Then chitosan, N-methyl chitosan, N-isopropyl chitosan are used as heterogeneous catalysts in the transesterification reaction of used cooking oil. The results showed that inclusion of alkyl groups to the chitosan structure leads to increase in the level of alkalinity in which chitosan, N-methyl chitosan, and N-isopropyl chitosan respectively are 0.066 mol/g, 0.0068 mol/g, 0.0070 mol/g . It is also evident from the increase in the area of methyl palmitate and methyl oleate. The use of Nisopropyl chitosan gave the greatest methyl ester yield results is about 8.6%.
