Hydraulic fluid compositions. Perilstein, Warren L. (Ethyl Corp., USA). U.S. US 3975279 17 Aug 1976, 6 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C09K050-00. NCL: 252078500. APPLICATION: US 75-634869 24 Nov 1975. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) The prepn. of a hydraulic fluid contg. .beta.-halopropyl thionophosphates and styrene oxide (I) [96-09-3] as additives is described. Thus, an additive conc. was formulated by blending I 39 parts by wt. tris(.beta.-chloropropyl) thionophosphate (II) [33712-72-0] 39, 2,6-di-tert-butylphenol [128-39-2], and neutral barium dionylnaphthalenesulfonate [25619-56-1], 20 parts by wt. Additives are blended with base stock fluids as follows: to 100 parts by wt. mineral oil is added 0.2 parts by wt. I stabilized II. 33712-72-0 and 128-39-2 are just another two chemicals used in this study. The mixt. is a stable mineral hydraulic oil. .

Adsorption of lubricating oil additives on solid surfaces (Part 3)

Adsorption of lubricating oil additives on solid surfaces (Part 3). Influence of polar compounds on the adsorption and desorption of additives. Tamura, Kunimitsu; Tse, James T.; Adamson, Arthur W. (Lubr. Pet. Prod. Lab., Nippon Min. Co., Ltd., Toda 335, Japan). Sekiyu Gakkaishi, 27(5), 385-91 (English) 1984. CODEN: SKGSAE. ISSN: 0582-4664. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) The influence of polar solvents on the adsorption phenomena of dinonylnaphthalenesulfonates and other additives on metal surfaces is examd. by ellipsometry. Ba dinonylnaphthalenesulfonate (I) [25619-56-1] adsorbed on a Au surface from hexane [110-54-3] soln. is not easily desorbed with hexane, whereas the film is desorbed with Me2CO [67-64-1]. The same result was obtained with Ca dinonylnaphthalenesulfonate [57855-77-3]. Succinimide dispersant is not easily desorbed by Me2CO. The same tendency was obsd. on Cr, and Fe alloy. When I is adsorbed from Me2CO soln. on Au, the adsorbed film consists of 2 layers, one of which is easily desorbed with Me2CO and the other not. The contact angles suggest that I adsorbed from hexane is different from that adsorbed from Me2CO in orientation. The adsorption behavior of I on Au from hexane-PrOH soln. is different from that on carbon black.
