Increasing the Quality of Lubricating Grease by Application of Compositions of Certain Additives Containing Sulfur and Phosphorus

Abstract

Additives were prepared from mixtures of diaryl dithiophosphates and triaryl dithiophosphates, obtained by reaction of P2S5 with alkylphenols (I) or methylenebis(alkylphenols) (II). Each of the di- and triester mixtures obtained from I and II was reacted with vinyl acetate and with CH2CMeCO2Me to give a total of 12 additives with surface-active properties. The inhibiting effect of 3% of each additive in greases on corrosion in neutral electrolytes was determined by the inhibition of the cathodic or anodic processes on metal. None of the additives had a significant thickening effect on the grease (Petrolatum), but increased the continuity of the grease film. The additives were efficient inhibitors of cathodic corrosion for the grease in sea water. Some of the additives also had an important inhibiting effect on the anode process.
