About Molybdenum Dithiophosphate liquid MoDTP:
Friction and wear properties of molybdenum dithiophosphate (MoDTP) additive under reciprocating sliding conditions. The additive consisting of pure MODTP is not effective for paraffin-based oils but is effective for engine oils containing P-S compounds such as zinc dialkyl dithiophosphate. The addition of P-O, P-S compounds and MODTP was effective for base oil and engine oil.
The surface film of molybdenum dithiophosphate is mainly composed of molybdenum sulfide and iron phosphate on the surface and molybdenum trioxide and iron phosphate on the surface.
The friction and wear properties of molybdenum dithiocarbamate (MODTC) and molybdenum dithiocarbamate (MODTP) were studied under reciprocating sliding conditions. Both MODTC and MODTP reduce friction and wear.MoS2 – the based surface film is formed by MODTC.MoDTP is mainly composed of MoS{SUB 2} and FePO{SUB 4} at 120 ° C, and MoS{SUB 2}, MoO{SUB 3} and FePO{SUB 4} at 200 ° C.MoS{Sub 2} films on the surface can effectively reduce the friction.The friction coefficient decreases with the increase of MOS {Sub 2} concentration in the surface film.Compared with MODTP, MODTC has higher capability of MOS {SUB 2} formation.Therefore, MODTC is superior to MODTP in reducing friction.

How is Molybdenum Dithiophosphate liquid MoDTP Produced?
The MODTP synthesis process includes:
Thiophosphating reaction (preparation of dialkyl orthophosphoric acid);
Molybdenum acidification (making molybdenum trioxide dissolve in an insufficient amount of sodium hydroxide and sulfuric acid);
Preparation of thiomolybdate (sodium molybdate and sodium hydride sulfur reaction);
Saponification reaction (reaction of orthophosphoric acid with molybdate or thiomolybdate) and extractive vacuum distillation (extraction of the Emperor reaction product by petroleum ether or hexane with an appropriate boiling point, and then decompression evaporation of hexane).
Applications of Molybdenum Dithiophosphate liquid MoDTP:
As lubricant additives, thiophosphate complexes of various metals endow lubricating oil with anti-wear, anti-friction, anti-oxidation and extreme pressure properties. Four molybdenum dialkyl thiophosphate (MOTP) complexes with alkyl chain lengths ranging from C5 to C10 have been synthesized. They have anti-friction, anti-wear and anti-oxidation properties in mineral oil, base oil and finished oil. The synthesized product has significant resistance to friction, wear and oxidation and is comparable to commercial MODTP.
Molybdenum dithiophosphate (MODTP) is used in internal combustion engine oils, industrial oils, gear oils and greases.
Recommended dosage 0.2-1.0%
