Abstract
Dithiophosphoric acid esters containing various functional groups have been synthesized. On the basis of allyloxybenzyl- and allyloxymethylbenzylchlorides, as well as sodium diisopropyldithiophosphate, allyloxybenzyl- and allyloxymethylbenzyldialkyldithiophosphates were obtained, respectively. 5-methyl-2-hydroxyphenylcarbonylmethyldiisopropyldithiophosphate was synthesized by the interaction of 5-methyl-2-hydroxy-chloroacetophenone and sodium diisopropyldithiophosphate. The synthesized compounds were studied as anti-wear and anti-seize additives for lubricating oils. Were also investigated their thermo-oxidative and anticorrosive properties. It was found that all synthesized compounds provide an improvement in the anti-wear and anti-seize properties of petroleum oils, and the efficiency depends on the presence of certain functional groups in the molecules of additives.
