Abstract
Technology was developed for production of TsD-7 dithiophosphate additive and its industrial production from a mixture of primary and secondary short-chain alcohols was organized. The lubricating, antioxidant, and scavenger properties of this additive in mineral oil were determined both combined with ash detergents and with no other additives in comparison to the properties of existing dithiophosphates. The results of bench engine tests of the new additive in group D motor oil are reported. The expediency of using the additive in oils for heavy-duty engines is demonstrated.
