Sulfuric acid was sulphonation reagent, add the sulfuric acidquantity was 8%, reaction temperature was 60~65℃.The reaction occursbetween the feed oil and sulfuric acid,then add 30% of sodium hydroxidesolution conducted neutralization in the Pyrex standard react kettle,when the reactionfinished ,draw out the products by funnel,then the products react with 8%clay to refine received the sulphonation refining oil so as to review property andreceive rate of the shallow sulphonation refining oil .By the using the sulphonationrefining oil to blend lubricant,its quality is on-specification .

为验证其可行性，首先在实验室进行浅度磺化小试，原料油采用新疆原油经常压蒸馏、减压蒸馏、溶剂精制、溶剂脱蜡后的减压二、三线脱蜡油，发烟硫酸作为磺化剂，发烟硫酸加入量8%，反应温度60～65℃，用三口圆底耐热玻璃标准反应釜对原料进行发烟硫酸磺化，加入量30%氢氧化钠中和，分液漏斗抽提，在烧杯内加入量8%白土进行精制得到磺化抽余油，考察浅度磺化抽余油性质和收率，用磺化抽余油调合润滑油质量合格。
