ABSTRACT:
Oligomers produced from lower olefins or alkenes by acidic zeolite catalyzed oligomerization can be converted to useful lubricant additives or lubricants by hydroxylation of olefinic bonds in the oligomers, whereby oligomers containing 1,2-glycol groups are produced. It has also been discovered that these glycols can be esterified to provide oligomers that also exhibit useful properties as lube additives or lubricants. The discovery is particularly applicable to the hydroxylation and esterification of oligomers produced from lower olefins such as propylene by oligomerization using ZSM-5 catalyst which has been surface deactivated.
