Abstract
The invention comprises the zinc salts of a mixture of phosphorodithioic acids of formula: <FORM:0852365/IV(b)/1> in which R1 and R2 are the same or different primary aliphatic hydrocarbon radicals selected from C1-4 radicals and C5+ radicals, the mole ratio of C1-4 radicals to C5+ radicals in the zinc salt mixture being within the range 1:1 to 3:1. They may be prepared by the separate preparation of individual zinc phosphorodithioates and subsequent mixing of these, or by the reaction of zinc oxide with a mixture of different phosphorodithioic acids. Such mixture may be obtained by reacting phosphorus pentasulphide with a mixture of alcohols. The salts may be prepared in a mineral oil suspension. Specifications 716,343 and 723,133 are referred to.ALSO:Lubricating oil compositions comprise as oxidation inhibitors the zinc salts of a mixture of phosphorodithioic acids of formula: <FORM:0852365/III/1> where R1 and R2 are the same or different primary aliphatic hydrocarbon radicals selected from C1-C4 radicals and C5+ radicals, the mole ratio of C1-C4 radicals to C5+ radicals in the zinc salt mixture being within the range 1:1 to 3:1. The compositions may be prepared by blending of components or by neutralising a suitable mixture of phosphorodithioic acids with zinc oxide in a mineral oil medium. Specifications 716,343 and 723,133 are referred to.
