Abstract

A solution of a divalent metal alkyl phenate or thiophenate in an inert solvent is reacted with elemental sulphur to give a complex reaction product as a concentrate in the inert solvent, and a proportion of a metal, ammonium or organic base salt of a petroleum mahogany acid is added to the concentrate. The final concentrate is useful as a detergent additive for lubricating oils and, as a result of the presence of the mahogany sulphonate, shows no tendency to deposit crystals on standing; in the absence of the mahogany sulphonate there is a tendency for the deposition of crystals of alkyl phenol or thiophenol, which is probably partially regenerated during the sulphurization reaction. The inert solvent may be lubricating oil and may contain a C8-C20 saturated aliphatic alcohol such as cetyl or stearyl alcohol to reduce foaming during the sulphurization reaction and to act as solubilizer of the sulphurized product. The divalent metal alkyl phenate or thiophenate may be an alkaline earth metal salt which may be a basic salt; similarly, the mahogany sulphonate may be an alkaline earth metal salt which may be a basic salt. The magnesium salts of both the alkyl phenol or thiophenol and the mahogany acid are also mentioned. The sulphurized product may be blown with carbon dioxide before or after the addition of the mahogany sulphonate. In an example, barium p-tert. octyl phenate, in mineral lubricating oil solution containing a mixture of cetyl and stearyl alcohols, is sulphurized and calcium mahogany sulphonate is then added. Specifications 586,841, 599,729 and 600,825 are referred to.
