摘　　要：介绍了一种分析、测定液体石油产品中羰基硫含量的新方法。该方法利用乙酸汞标准溶液滴定到乙二胺溶液吸收羰基硫,并根据所消耗的乙酸汞标准溶液的体积计算羰基硫含量。实验结果表明,该方法的收率为96.40%,标准偏差为1.54,变异系数为3.60%,这些分析数据具有较好的准确度和可信度;同时,该分析方法也不失为一种实用、有效测定羰基硫的方法。In this paper, an analysis method to analyze the carbonyl sulfide content in the petroleum products have been realized. This method was used to titrate the carbonyl sulfide adsorbed in the ethylene dimine liquid with mercury acetate standard liquid. So that we can calculate the carbonyl sulfide content according to the consumed volume of the mercury acetate standard liquid. The analysis results showed the recovery is 96.40%, the standard deviation is 1.54 and coefficient of variation is 3.60%. The analysis data is sufficient and the method is reliable with good accuracy.
