Abstract
Cinnamic acid was synthesized from cinnamaldehyde by oxidation with air and oxygen respectively using transition metal salt such as cobalt acetate,copper acetate,nickel acetate and self-made Ag/C as catalyst.Effects of catalyst,catalyst volume,catalytic ability after regeneration,reaction time and temperature on yield of the product were investigated.The yield of cinnamic acid could reach 93 5% using Ag/C as catalyst,oxygen as oxidant,at a temperature of 40～45 ℃,and with reaction time of 1 5 h.
