摘　　要：通过在超高碱值烷基水杨酸钙的合成过程中引入助表面活性剂和助促进剂,研究了反应助剂对产品收率和产品性能的影响。结果表明:随着助表面活性剂用量的增加,产品收率逐渐升高后达到平衡,加入硬脂酸、烷基苯磺酸及十二烷基酚等助表面活性剂后均可显著提高产品收率;助促进剂中,乙酸对反应的促进作用最明显,且其用量(w)为1.5%时产品收率最高;不同助表面活性剂与乙酸共同使用时的产品收率高于两者单独使用时的产品收率,且以硬脂酸与乙酸配合使用时的反应效果最好,产品收率可提高至98%以上,所制备出的超高碱值烷基水杨酸钙黏度低、与磺酸盐的配伍性好,其综合性能优异。The preparation method of super overbased calcium salicylate was introduced.The effect of additives on the product yield was studied by using co-surfactants and co-promoters.The results showed that with the increase of the amount of co-surfactant,the yield of the product increased gradually and reached a balance;the addition of co-surfactants such as stearic acid,alkyl benzenesulfonic acid and dodecylphenol significantly improved the yield of the product.In the co-promoters,acetic acid was the most effective co-promoter and the yield was the highest when the dosage(w)was 1.5%.Result showed that when co-surfactant used together with the acetic acid the product yield was higher than both the yields when used alone.Among them,the effects of stearic acid and acetic acid combination was the best,with the product yield as high as 98%.The prepared super overbased calcium salicylate has low viscosity,good compatibility with sulfonate and excellent comprehensive performance.
