Complex antimony sulfides as lubricant additives: Complex antimony sulfides as lubricant additives. Soulen, John R. (Pennwalt Corp., USA). U.S. US 3965016 22 Jun 1976, 3 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C10M001-10. NCL: 252025000. APPLICATION: US 75-580859 27 May 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 49 The extreme-pressure and antiwear properties of lubricants were promoted by addn. of amorphous SbxSy (x = 1.7-2.3, y = 3.6-4.4) m. .apprx.510.degree.. Thus, a soln. of Sb2O3 in excess 50% KOH was added to Na3SbS4 [13776-84-6] and dild. with HCl and H2O. After neutralization with HCl, the slurry was stirred 1 h at 95.degree., washed to remove Cl-, and dried at 75.degree. to yield Sb2S4 [12359-48-7] complex. In the Shell 4-ball test, the weld points of samples of a Li diester grease contg. 5% amorphous Sb2S4, cryst. Sb2S3, or MoS2 were 600, 355, and 140 kg loads, resp. When placed on the abraded skin of rabbits, the Sb2S4 complex produced erythema and edema with complete recovery in 2 weeks, compared with the arsenic thioantimonate, which produced erythema, edema, and ecchymosis from which there was very little recovery in 2 weeks.

Coloring of 18-8 stainless steel: Coloring of 18-8 stainless steel. Murakami, Tadamitsu (Sakai Anticorrosion Chemical Industries Co., Ltd., Japan). Japan. Kokai JP 53037151 6 Apr 1978 Showa, 2 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C23F007-04. APPLICATION: JP 76-112241 17 Sep 1976. DOCUMENT TYPE: Patent CA Section: 55 (Ferrous Metals and Alloys) The 18-8 stainless steel [12671-80-6] is treated with a soln. (140-45°) contg. Na thioantimonate [13776-84-6], NaOH, and NaNO3 (oxidant) to blacken the steel.
