Claims
- 1. A process for the preparation of a high-temperature stable lubricant fluid or lubricant additive comprising reacting in the presence of a zeolite catalyst (1) an olefinic alkylating agent containing from 12 to about 500 carbons and optionally containing S, N, O, P, F, or mixtures thereof, and (2) a diphenyl ether wherein the reaction temperature varies from ambient to about 350.degree. C., the molar ratio of said alkylating agent to diphenyl ether varies from 0.5:1.0 to about 10.0:1.0, the amount of catalyst varies from 5 to about 100 grams of catalyst to about 1 mole of diphenyl ether, and the reaction product comprising a substantially monosubstituted adduct.
- 2. The process of claim 1 wherein the alkylating agent is a C.sub.8 to C.sub.18 alpha-olefin.
- 3. The process of claim 1 wherein the catalyst is selected from zeolites X, Y, UHP-Y, ZSM-20, zeolite beta and MCM-22.
- 4. The process of claim 1 wherein the catalyst is an ultrastable Y zeolite catalyst.
- 5. The process of claim 1 wherein the alkylating agent is 1-tetradecene and the catalyst is an ultrastable Y zeolite catalyst.
- 6. The process of claim 1 wherein the alkylating agent is 1-dodecene and the catalyst is an ultrastable Y zeolite catalyst.
