Abstract

1388247 Hydraulic fluids CHEVRON RESEARCH CO 31 July 1973 [31 July 1972] 36455/73 Heading C5F Hydraulic fluids contain 0À1 to 1À5 wt. per cent of zinc di-(primary iso-octyl) dithiophosphate, 0À03 to 0À2 parts by weight of a C 6 to C 24 alkenyl succinic acid per part of the zinc dithiophosphate, and, when the content of zinc dithiophosphate is equal to or above 1%, 0À01 to 0À1 part of a metal deactivator per part of the zinc dithiophosphate. Lists of suitable mineral or synthetic base oils and conventional additives are given. The base oils used in the examples are turbine oils. The metal deactivators used in the examples are tricresyl- and tributyl-phosphates, benzotriazole, and didecylphenyl phosphite otyer deactivators listed are alkylphenol sulphides, phosphorus pentasulphide-terpene addition products, phenothazin, bis octyl dithiathiadiazole and phenyl-1-naphthylamine. The hydraulic fluids produced in the examples also contain 0À05 wt. per cent zinc sulphonate as a demulsifier, and a polymethacrylate pour point depressant, and 0À002 wt. per cent of a silicone oil foam inhibitor.
