摘要
以冰醋酸、三氯甲烷、甲醇和1:5的硫酸(体积比为714:134:134:18)作为滴定溶剂,采用电位滴定法测定石油产品的溴值,并与指示剂滴定法进行对比。结果表明,该方法相对误差小,操作简单,结果准确可靠。尤其使用于深色石油产品。
The bromine value of petroleum products was determined by potential titration in mixed solvents of glacial acetic acid,trichloromethane,methanoland sulfuric acid,this method was compared with indicator titration,the experimental results show the method relative standard deviation is smaller.This method is handy,dependable and could be applied to various petroleum products.
