The oxidation and degradation of hydrocarbons at high temperature and pressure in the presence of oxygen is one of the common oil product problems. There are many antioxidants to prevent or inhibit oxidation processes; molybdenum and zinc dithiocarbamates are known as powerful antioxidants. In this paper, the oxidation inhibition time of cumene has been investigated using zinc and molybdenum di...

Abstract Molybdenum dialkyl dithiocarbamate (MoDTC) is a friction reducing additive commonly used in lubricants. MoDTC works by forming low-friction molybdenum disulphide (MoS 2 ) film (tribofilm) on rubbed surfaces. MoDTC-induced MoS tribofilms have been studied extensively ex-situ ; however, there no consensus the chemical mechanism of its formation process. By combining Raman spectroscopy wi...

Abstract Organic molybdenum lubricant additive like dialkyl dithiocarbamate (MoDTC) can cause wear acceleration of diamond-like carbon (DLC) coating coupled with steel under boundary lubrication, which hinders its industrial application. Therefore, polyisobutylene succinimide (PIBS), an organo amide, was adopted to modify oxide affording succinimide-molybdenum nanoparticles (MPIBS-MONPs) potent...

Abstract Lubricants have played important roles in friction and wear reduction increasing efficiency of mechanical systems. To optimize tribological performance, chemical reactions between a lubricant substrate must be designed strategically. Tribochemical are enabled or accelerated by stimuli. Tribochemically activated additives play these reactions. In this review, current understanding mecha...

Nano dithiocarbamate (DTC) complex have been prepared by reaction between dithiocarbamate and metal salt under ultrasound irradiation. Reaction conditions such as the ligand DTC and phennantroline concentration, aging time and the ultrasonic device power show important roles in the size, morphology and growth process of the final products. The dithiocarbamate complex nanoparticles have been pre...
