| Abstract: | Octadecyl naphthenate was synthesized from naphthenic acid and octadecyl alcohol with phosphotungstic acid as 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 were studied.The experiment results indicated that the product yield can arrive at more than 90 percent under the suitable conditions.Compared with sulphuric acid as catalyst,ester yield can increase more than 10 percent. |
