Neutral and Basic Dialkildithiophosphate Structure Investigation

Neutral and basic zinc diisobutyldithiophophate (ZDDP) were synthesized and their structure was investigated. Diisobutyldithiophosphoric acid, neutral and basic ZDDP chemical composition was confirmed by elemental analysis. Obtained neutral and basic ZDDP differed by physical-chemical properties. IR-spectra comparison of neutral and basic ZDDP shows absence of absorption band which corresponds to hydroxyl group. XRD investigation neutral and basic ZDDP results in definite formulas and structures. Basic ZDDP is tetranuclear zinc complex with six organic ligands, and oxygen atom in centre of tetrahedron formed by four zinc atoms. Such structure give extensionality to basic ZDDP molecule and give an explanation to differ physical-chemical and antiwear properties. Thus by complex of proposed methods structure of such substances can be discovered for purposeful synthesis.
