Result shows that the sulfur compounds in the diesel can react with iodomethane easily at room temperature, the most of sulfur compound derived into methylsulfonium salts; the homologue of benzothiophene get the higher conversion ratio and react selectivity than the homologue of dibenzothiophene. It is found that primarily sterically hindered alkylated DBT, for example, 4-or 4-, 6-DBT, is recalcitrant to be methylated.

结果表明：柴油中硫化物在室温条件下容易与碘甲烷发生甲基化反应，大部分硫化物转化为锍盐，总转化率超过80%，苯并噻吩类比二苯并噻吩类更易发生甲基衍生化反应，转化率也相应较高。
