摘要: Abstract The esterification of oleic acid in subcritical methanol catalyzed by zinc acetate was investigated a batch-type autoclave. effect reaction conditions such as temperature, pressure, time and molar ratio to on the examined. conversion reached 95.0% under 220 °C 6.0 MPa with being 4 1.0 wt% catalyst. A kinetic model for established. By fitting experimental results, order n = 2.2 activation energy Ea = 32.62 KJ/mol were obtained.
