Abstract
Lubricants used in technology should have sufficient protective properties to effectively protect metal parts from rust during operation, as well as during short and long-term idle stops. One of the effective ways to solve this problem is to add effective preservative (conservation) additives to lubricants, which do not adversely affect the operating properties of lubricants and improve their preservation properties. For the purpose of synthesis and research of effective protective additives for lubricating oils, 3-chloro-2- hydroxypropylisobutyl ether was obtained by treating isobutyl alcohol with epichlorohydrin. By adding NaOH to 3-chloro-2-hydroxypropylisobutyl ether, synthetic substance – 3,2-epoxypropylisobutyl ether was synthesized. 3-piperidine-2-hydroxypropylisobutyl ether was synthesized by treating 3,2-epoxypropylisobutyl ether with piperidine. The structure of substancу was confirmed by IH , 13C NMR spectroscopy. The corrosion efficiency of the compound was studied. It became clear that these compounds are more effective than the industrial additive – alkenylsuccinimide urea.
