E-mail: ermolaeva_n_v@mail.ru <mailto:ermolaeva_n_v@mail.ru> Molecular composition of I-40A industrial oil as well as lubricating-cooling liquids (LCL) such as SP-4, MR-3, MR-3K is studied by chromatography-mass-spectrometry method. The results of the study witnessed absence of chlorine-containing components only in MR-3 and MR-3K of oil LCL. Impact of sulfur content of oil LCL on treatment quality is studied as well.
