【Abstract】 Octadecyl naphthenate was synthesized from naphthenic acid and octadecyl alcohol with phosphotungstic acid catalyst . The influence of synthesis conditions such as the structure and quantity of catalyst ,the mole ratio of naphthenic acid to octadecyl alcohol ,the quantity of watercarrying agent, reaction temperature and time on esterification and the influence of conditions such as alkali washing,decolor on the quality of production were studied.更多还原
