We have developed the synthesis pathways of molybdenum trisulfide nanoparticles that are soluble in hydrocarbon media and demonstrate their activity as antifrictional and antiwear additives to lubricants. Bis(tetraalkylammonium)tetrathiomolybdates as precursors of molybdenum trisulfide nanoparticles are synthesised by the interaction of ammonium thiomolybdate with tetraalkylammonium halides, including alkyl groups of the various types. The properties of synthesised molybdenum compounds were determined by UV- and IR-spectroscopy and by thermogravimetric analysis. The molybdenum trisulfide nanoparticles were formed by thermolysis of these compounds, and their sizes and size distribution were determined by small angle X-ray spectroscopy. The antifrictional and antiwear activity of molybdenum compounds and MoS3 nanoparticles were evaluated using various types of tribometers.
