Abstract: There is provided a method for selectivating a zeolite, such as ZSM-5 which may result in functionalization of the zeolite with at least one organosiliceous group of the formula, SiR.sub.n (OX).sub.4-n, where R is at least one hydrocarbyl group, n is 1 or 2 and X is Si or H. This selectivation method involves vapor phase treatment of a zeolite with an organosilicon compound having at least 2 silicon atoms. This organosilicon compound may be a silicone compound, such as hexamethyldisiloxane, or a silane compound such as hexamethyldisilane. This contacting may take place in the presence of hydrogen and an organic carrier. The functionalized zeolites may provide a catalyst which is both highly active and highly selective for converting aromatic hydrocarbons, especially alkylbenzene compounds, to products comprising the para-isomer of dialkylbenzenes. The disproportionation of toluene is an example of such a reaction.

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.
