Abstract: Reactive S (e.g. H.sub.2 S and mercaptans) in petroleum liquid are scavenged by the use of oil soluble trialkyl hexahydro triazines wherein at least one alkyl group, and preferably all three, contain from 7 to 20 carbon atoms.

Abstract translation: 通过使用油溶性三烷基六氢三嗪来清除石油液体中的活性S（例如H 2 S和硫醇），其中至少一个烷基，优选全部三个含有7至20个碳原子。
