The hexadecanol bischloroacetate was synthesized fastly with the technique of microwave irradiation with the anhydrous cupric sulfate as catalyst. The optimal reaction conditions are as follows: the mole ratio of hexadecanol and chloroacetic acid is 5∶1(mol/mol), the amount of catalyst 2.0g, the power microwave 729W, the ratiating time of microware 5 min. Under the conditions the yield is 83.6%. The molecular structures of the fatty alcohol chloracetates were characterized by IR.
