| Abstract：A method of catalytic synthesis of chloroacetic long-chain fatty alcohol esters was reported. The target compounds were synthesized in the yields of 90.1%~98.3% from chloroacetic acid and long-chain fatty alcohols as raw materials via reflux, dehydration and esterification in cyclohexane using stannous chloride as a catalyst within two hours. The effects of various factors on the reaction yields were studied. |
| Key words：chloroacetic long-chain fatty alcohol ester; chloroacetic acid; long-chain fatty alcohol; catalyst |
