1, 2-EPİTİO-3-XLORPROPANIN DİETİLDİTİOKARBAMATLA REAKSİYA MƏHSULLARININ SÜRTKÜ YAĞLARINA YEYİLMƏ VƏ SİYRİLMƏ ƏLEYHİNƏ AŞKAR KİMİ TƏDQİQİ. (Azerbaijani)

This article is dedicated to the investigation of the synthesis of S-substituted thiiranes and thietanes-some derivatives of three- and four-membered heterocyclic sulfur compounds, respectively, specifically, S-(1,2-epithiopropyl) -N,N-dialkyldithiocarbamates and 3-N,N dialkyldithiocarbamatethiethanes, as anti-corrosion and anti-stripping additives to their lubricating oils, in order to find more effective new types of lubricant additives. The article also studied the correlation between the structure of the synthesized substances and their effectiveness as an additive for lubricating oils. As a result of the conducted scientific research, it was found that if the reaction of ETXP with, for example, sodium-diethyldithiocarbamate is carried out in dry benzene (in anhydrous conditions) at a temperature of 60- 70°C for 3 hours, the reaction product consists only of the corresponding thiirane derivative. If this reaction is carried out under the indicated conditions in an aqueous medium, thiirane-thietane regrouping occurs and the corresponding thiirane-thietane mixture is obtained as a result. The effect of the synthesized diethyldithiocarbamate-substituted thiirane and thietane MS-20 transmission oil on the corrosion and stripping properties was tested. It has been found that diethyldithiocarbamate-substituted thiirane and thietane derivatives have a substantial effect on the corrosion and stripping properties of lubricating oils. In thiirane compounds, the fragment bearing lubricating properties is a three-membered thiirane ring, in thietane compounds is a-four-membered thietane heterocyclic. [ABSTRACT FROM AUTHOR]
