Abstract: Sodium di-n-butyl naphthalene sulfonate was prepared from n-butyl al-cohol, naphthalene and fuming sulfuric acid. Di-isoamyl naphthalene sul-fonate was prepared similarly. Their wetting properties were tested by the modified Draves method. Dibutyl naphthalene sulfonate was found to be avaluable wetting agent and could be made from cheap raw materials.

摘要： 本文提供二正丁基萘磺酸钠及二异戊基萘磺酸钠之制备方法.前者可从正丁醇、萘、及发烟硫酸制得,后者可用异戊醇代替正丁醇.此两种萘磺酸钠之浸湿作用会用与Draves法相似之方法加以测定,并与土耳其红油之浸湿作用相比较.根据实验之结果,知二正丁基萘磺酸钠之浸湿力较土耳其红油为高,乃良好之浸湿剂;但二异戊基萘磺酸钠之浸湿力并不较土耳其红油为高.
