Abstract The lubricity of 4-acryloyloxyphenyl ester of 4'-n-octyloxybenzoic acid and the system composed of p-n-propyloxybenzoic acid and p-n-propyloxy-p'-cyanobiphenyl in the conditions of boundary friction was investigated. The studies were carried out both for pure substances and their solutions in the liquid paraffin base. It was established that the studied additives possess good tribological properties. The tribological activity is defined by chemical structure and concentration of the additive in solution. The presence of the triboactive additives in lubricant stabilizes tribological properties of the lubricant on heating.
