Synthesis of Octadecanol Oleic Catalyzed by Metal Powder C-1

Octadecanol oleic was prepared with oleic and octadecanol as raw materials and metal powder C-1 as catalyst.The influential factors such as type and amount of catalyst,reaction time,raw material ratio and reaction temperature were investigated.And the octadecanol oleic structure was characterized by IR.The tribology performance was investigated by four-ball machine.It showed that the optimum reaction conditions were as follows:the reaction temperature was 180~190℃;the molar ratio of oleic to octadecanol was 0.9∶1;the amount of catalyst was 0.50% of the whole raw materials;the reaction time was 3 h.Under above optimum conditions,the esterification rate was more than 95%.Octadecanol oleic had good tribological performance.
