摘要
以抚顺石油一厂减五线馏分油溶剂精制后的抽出油为原料,采用发烟硫酸为磺化剂进行磺化反应制取石油磺酸,进而制取石油磺酸钠。在磺化反应过程中主要考察了反应温度、反应时间和酸油比对石油磺酸收率的影响。在酸油体积比为0.12∶1,反应温度60℃,反应时间45 min的条件下,磺化物质量收率为64.14%。与10%氢氧化钠中和反应,用乙醇水溶液在60℃条件下萃取出石油磺酸钠,并测定出萃取液中活性物质量含量为42.1%,可作为采油驱油剂使用。
Petroleum sulfonate is obtained through sulfonate reaction using extract oil from refining VGO. no. 5 in the No. 1 refinery of Fushun as raw materials and oleum as sulfonation agent in this paper. And the effect of reaction conditions such as acid/oil ratio, temperature and reaction time on product yield is studied. The yield of petroleum sulfonate is 64. 14% when acid/oil ratio is 0.12：1, temperature is 60℃ and reaction time is 45 min. After petroleum sulfonic acid is reacted with 10% sodium hydroxide, petroleum sulfonate is obtained by extraction with ethanol and its active substance content is 42.1%, which can he used as surface active reagent.
