石油磺酸盐早在三十年代就被选作缓蚀剂使用,直至今天仍是首选的主要油溶性防锈添加剂之一。特别在国内几乎所有的防锈油脂都使用它,一般添加量在10%以下(见附表1几种国内主要的防锈油脂配方)。石油磺酸盐,可在石油加工白油时作副产品获得。即在从石油加工成白油过程中用发烟硫酸磺化除去白油中的芳香烃,芳香烃的磺化生成就是石油磺酸,然后用不同的氢氧化物中和,制成相应的盐类——石油磺酸盐。由于所选用的中和剂(例如氢氧化钡、氢氧化钠。氢氧化钙)不同,就能得到三种 Petroleum sulfonate was chosen as a corrosion inhibitor as early as the 1930s and remains one of the major oil-soluble anti-rust additives of choice until today. Especially in the domestic use of almost all anti-rust grease, the general addition of less than 10% (see Schedule 1, several major domestic anti-rust grease formula). Petroleum sulfonate, available as a by-product when processing white oil from petroleum. That is, in the processing of white oil from oil to oleum with sulfonated sulfonated white oil to remove aromatic hydrocarbons, sulfonation of aromatic hydrocarbons generated is the oil sulfonic acid, and then with different hydroxides to make the corresponding salt Class - petroleum sulfonate. Due to the choice of neutralizing agents (eg barium hydroxide, sodium hydroxide, calcium hydroxide), three types of
