| Abstract: | Isopropyl palmitate was synthesized from palmitic acid and isopropyl alcohol under microwave irradiation with Ce(SO_4)_2/SiO_2 as catalyst and 3A molecular sieve for dehydration.The optimal reaction conditions were found as flows:molar ratio of isopropyl alcohol to palmitic acid 6:1,weigh ratio of catalyst to palmitic acid 1:5,microwave power 300 W and irradiation time 30 min.Under these conditions,the yield of the ester was above 90.4%.The product was characterized by refractive index and FT-IR. |
