摘　　要：以油酸、顺丁烯二酸酐、二乙醇胺为原料 ,经加成与酰胺化两步反应 ,合成了油酸酰胺基非离子表面活性剂 OMA。在催化剂 PB和 KOH存在下 ,控制两步反应温度分别为 1 70～ 1 80℃和 1 50～ 1 65℃ ,w ( PB) =0 .3 % ,n (油酸 )∶ n (顺丁烯二酸酐 )∶ n (二乙醇胺 ) =1∶ 1 .1∶ 3 .3 ,总反应时间 5～ 6h,产物收率达 82 %。OMA水溶性好 ,抗硬水、耐水解能力强 ,在 p H值 5～ 1 0水溶液均能稳定存在 ,具有很好的稳泡性和较好的润湿、乳化能力 ;在水中对黑色金属有优良的防锈性能 ,对铜也有一定的防腐蚀效果 ,适用于水基金属切削液等水基型体系。An oleoyl amido nonionic surfactant OMA was prepared in the first step by addition of oleic acid with maleic anhydride at 170～180 ℃ using PB as catalyst, w(PB)=0.3%, and then in the second step by amidation of the intermediate with diethanolamine at 150～165 ℃ using KOH as catalyst. The total reaction time was 5～6 h, n(oleic acid)∶n(maleic anhydride)∶n(diethanolamine)=1∶1.1∶3.3, the yield of OMA was about 82%. The results of experiments showed that OMA has good watersolubility and hydrolysis resistance, its water solution could exist stably in the range of pH 5～ 10, it has good foam stability, wetting ability emulsibility and rust inhibition of steel and cast iron than that of copper in water medium. So it is be applicable in waterbase cutting fluids.
