Additives in an oil with a viscosity of 20.8 centistokes at 50° were tested in a modified 4-ball machine for reduction of wear and load-carrying capacity. Chlorinated compounds, such as methyl dichlorostearate, tetrachloronaphthalene, and chlorinated wax fractions increase the critical load and lower frictional wear by chem. reaction at high temperature Optimum results were obtained with >7% of chlorinated fractions containing >40% Cl. Tests on organic S-P compounds indicated that the activity of organic phosphites depends on the structure of the hydrocarbon radical; e.g., the critical load for an oil containing tripropyl trithiophosphite is 110 kg., almost twice that of the base oil or of the oil containing tri-noctadecyl trithiophosphite. Only lower trialkyl trithiophosphites with C3-C5 alkyls, are potential additives for increasing the lubricating properties of oils; trialkylthiophosphates are less active. Butyl esters of phosphorous, phosphoric, thiophosphorous, and thiophosphoric acids are active additives. Increasing the S content of phosphites, and particularly of phosphates, resulted in a reduction of the critical load but reduced wear above the critical load by formation of a sulfide film on the frictional surfaces under heavy load and at high temperature P in the mol. increased the critical load and S improved frictional behavior. Cl reduced wear even more than S. Phosphonic compounds were more active than compounds containing alkoxy groups, e.g., trichloromethyl phosphonates (I) and dichloroethyl chloroethylphosphonate increased the critical load from 68 to 140-50 kg. and reduced wear at loads higher than the critical load. Tetrachloroalkanes increased the critical load and reduced wear above the critical load but compounds containing the CCl3 group and P, such as I, are markedly more active owing to action of the trichloromethyl group and of P from additive decomposition Increasing the number of CCl3 groups in the mol. of organic P compounds enabled an oil containing such an additive to carry enormous loads without seizure, e.g., tri(trichloroethyl)phosphite and tri(trichloro-tert-butyl)phosphite reduced wear to lower than 0.8 mm. at 300 kg. loads. 21 references.
