文章介绍了一种测定石油馏分中腐蚀性硫的方法。该方法基于石油馏分中腐蚀性硫能与铜粉反应，将铜粉及腐蚀产物过滤后测定硫含量，并与铜粉反应前的硫含量比较，两者之差即为腐蚀性硫的量。文中讨论了反应温度、时间、铜粉加入量等对标样及石油馏分中腐蚀性硫测定结果的影响，给出了测定石油馏分中腐蚀性硫的实验条件。
This article describes a method for determining corrosive sulfur in petroleum fractions. The method is based on the reaction of corrosive sulfur energy with copper powder in petroleum fractions, the determination of sulfur content after filtration of copper powder and corrosion products, and the comparison with the sulfur content before copper reaction, the difference between the two is the amount of corrosive sulfur. The effects of reaction temperature, time, the amount of copper powder on the determination results of corrosive sulfur in petroleum samples and petroleum fractions were discussed in this paper. The experimental conditions for determination of corrosive sulfur in petroleum fractions were given.
