Claims
- 1. A lubricant composition comprising a mixture of phenyltrialkylsilanes having the formula RSi(R').sub.n (R").sub.3-n wherein R is a phenyl group and R' and R" are each independently selected from normal alkyl groups having from about four to about sixteen carbon atoms and n is one, two or three, and wherein the number of carbon atoms in R' and R" differ by at least about two.
- 2. The composition in claim 1 wherein the number of carbon atoms in R' and R" differ by about two.
- 3. The composition in claim 1 comprising aRSi(R').sub.3, bRSi(R').sub.2 (R").sub.1, cRSi(R').sub.1 (R").sub.2 and dRSi(R").sub.3, wherein a, b, c and d represent the ratio of the phenyltrialkylsilanes in the mixture.
- 4. The composition in claim 3 wherein a and d are approximately equal and b and c are approximately equal and greater than a or d.
- 5. The composition in claim 4 wherein the ratio a:b:c:d is about 1:05 to 15:0.5 to 15:0.5 to 2.
- 6. The composition in claim 5 wherein the ratio a:b:c:d is about 1:3:3:1.
- 7. The composition in claim 1 wherein the phenyltrialkylsilanes comprise the reaction product of olefin mixtures comprising approximately equal portions of normal olefins having six and eight carbon atoms respectively, eight or ten carbon atoms respectively, or ten or twelve carbon atoms respectively; sodium aluminum hydride; and tetrahalosilane or organo-trihalosilane.
