Antiwear additive mixture

Antiwear additive mixture. Pratt, Robert E.; Habzansky, John (Bray Oil Co., USA). U.S. US 3970570 20 Jul 1976, 4 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C10M001-10. NCL: 252049900. APPLICATION: US 75-638468 8 Dec 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) The antiwear properties of lubricating oils are improved by the addn. of a mixt. of 1-2 wt. % tricresyl phosphate (I) [1330-78-5] and 0.5-1 wt. % pentaerythritol monooleate (II) [10332-32-8]. This synergistic additive combination is ashless, has good oxidn. stability, and is noncorrosive to Cu at >300.degree.F. Thus, a prototype gas turbine lubricating oil (viscosity .apprx.6 cSt at 210.degree.F, flash point >450.degree.F, pour point <-65.degree.F) was prepd. using as base oil a hydrogenated linear .alpha.-olefin oligomer produced by the polymn. of 1-decene. An antioxidant, a seal-swell agent, and a metal deactivator were added, along with varying amts. of I and II. The antiwear properties of the blends were tested in the Falex lubricant tester and in the Shell 4-ball app. The blends contg. 10332-32-8 and 71-43-2 are just another two chemicals used in this study. I and II had better antiwear properties than the blends contg. I or II only. The additive combination was also effective when the base oil used was ridecyl adipate [16958-92-2], C10-15 dialkylbenzene, or methyl chlorophenyl silicone oil. .

Dialkyl adipate lubricants preparation using tantalum (V) halide/oxide-inorganic oxide catalysts

Dialkyl adipate lubricants preparation using tantalum (V) halide/oxide-inorganic oxide catalysts. Johnson, Thomas H. (Shell Oil Co. , USA). U.S. US 4623748 A 18 Nov 1986, 8 pp. (United States of America) CODEN: USXXAM. CLASS: ICM: C07C067-08.There are some reagents with their cas registry numbers 16958-92-2 and 151-32-6 are used in this study. NCL: 560204000. APPLICATION: US 85-704984 25 Feb 1985. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Synthetic lubricants are manufd. by reacting propylene oligomers or butylene oligomers from the Dimersol process in the presence of a Ta (V) halide (or oxide)-inorg. oxide catalyst, converting the resulting C8-12 olefins to C9-13 alcs., and reacting the alc. with adipic acid to produce dialkyl adipates with higher flash points. Thus, a synthetic lubricant was prepd. by reacting propylene oligomer with a TaCl5-SiO2 catalyst, converting C8-12 olefins to alcs., and reacting the alcs. with adipic acid to produce dinonyl adipate, which had a flash point (ASTM D-92)) of 455°F, vs. 390°F for the adipate prepd. from conventional oxo alcs. .
