清净分散剂是现代各种内燃机润滑油所用的主要添加剂。目前国内外所用的清净剂一般为:磺酸盐、硫化烷基酚盐和水杨陵盐等。在金属类型上,除钙盐继续作为主要金属盐外,镁盐的应用日益广泛。特别是高碱度(总碱>300mgKOH/g)的镁盐,目前在国外已有工业产品或正在开发产品,如高碱度镁和水杨酸镁等。为了适应这种发展形势,我们在合成新型高碱度镁盐清净剂中,进行了清净剂中金属镁含量的分析研究。清净剂中镁的含量分析采取化学分析法和原子吸收法。前者是用络合滴定法测定试
Clean Dispersant is a modern variety of internal combustion engine lubricants used by the main additives. At present, the detergents used at home and abroad are generally: sulfonate, sulfurized alkyl phenate and water Yangling salt. In the metal type, in addition to calcium salts continue to be the main metal salts, magnesium salts are increasingly widely used. Especially the high alkalinity (total alkalinity> 300mgKOH / g) magnesium salt, at present there are industrial products abroad or are developing products, such as high basicity magnesium and magnesium salicylate. In order to adapt to this kind of development situation, we have carried on the analysis research of the metal magnesium content in the detergent in synthesizing the new high basicity magnesium salt detergent. Detergent magnesium content analysis to take chemical analysis and atomic absorption method. The former is measured by complexometric titration test
