摘　　要：用二甲基亚砜精制催化裂化柴油 ,是提高柴油氧化安定性的一项新技术。精制后柴油中携带二甲基亚砜的多少 ,是生产过程控制产品质量的关键。本文依据生产工艺原理和溶剂的物化性质 ,建立了用蒸馏水萃取柴油中二甲基亚砜 ,电量法测定萃取液中的硫含量 ,根据溶剂分子结构 。refining diesel by dimethylsulphoxide is a new technique that increase the stability of diesel. Controlling the quantity of dimethylsulphoxide in refined diesel is a key to production process. According to the principle of production technique and the character of solvent, we establish an analysis method to measure the quantity of dimethylsulphoxide in refined diesel. The method include extracting the dimethylsulphoxide in refined diesel with distilled water, measuring the sulphur in extraction liquid by electrical method and calculating the quantity of dimethylsulphoxide by solvent molecular structure.
