ABSTRACT:
Oligomers produced from lower alkenes by acidic zeolite catalyzed oligomerization can be converted to useful lubricant additives or lubricants by amidation and sulfonation of olefinic bonds in the oligomers by reaction with nitriles in the presence of strong acid catalyst whereby oligomer derivatives containing amide groups and sulfonic acid groups are produced. The products so produced from C.sub.20 + olefins exhibit favorable qualities as lubricants. The discovery is particularly applicable to the amidation and sulfonation of oligomers produced from lower olefins such as propylene by oligomerization using a ZSM-5 catalyst which has been surface deactivated.
