摘　　要：使用自动电位滴定仪测定轻质石油产品中的溴值,分析速度快,克服了容量法分析石油产品过程中分析时间长,人为影响因素多的原因,分析结果重复性好。对于深色石油产品也可以很好地进行分析,消除了分析深色石油产品的溴值时无法准确判断其终点的缺陷。Determination of light petroleum products in bromine value using automatic potentiometric titrator , with fast analysis speed , to overcome the capacity analysis of petroleum products in the long analysis time , and many reasons of human influenced factors , the analysis results were good and repeatability.For petroleum products , it can also be well analyzed to eliminate the defect analysis of dark petroleum products of bromine value which can not accurately determine the endpoint.
