... of the products was analyzed by means of Fourier transformation infrared spectrometry, elemental analysis, and so on. The thermal stability of the products was evaluated by thermogravimetric analysis. The tribological properties of the synthesized borate esters as lubricating oil additives in liquid paraffin were...

...-butylpolysulfides (DIBPS). The copper corrosion-inhibiting performance and thermal stabilities of the additives were explored as well. The results showed that the synthetic heterocyclic polysulfides had better corrosion-inhibiting properties and thermal stability than the DIBPS. Moreover, the heterocyclic...
