Abstract

The molecular composition of oil-based lubricoolant SP-4 was researched with the chromatography-mass spectrometric method. There was discovered 5 alkens, 2 sulfur-, 8 oxygen-, 6 halogen-containing and other compounds. The quantity of them is 0,3...10 mkg/g and to represent danger to man and environment. There were detected the series of the specific requirements to the lubricoolants which are using in machining processes. There was suggested to introduce instead of a term “eco-friendly (safety)” lubricoolant a term “ecological”. In turn understood by the ecological lubricoolant you should such a lubricoolant, which makes a minimal loss for environmental and man during the preparative, operation and recycling.

Keywords

lubricoolant; alkens; sulfur-containing, oxygen-containing and halogen-containing components; environmental protection; ecological.
