Synthesis and Multiple-Effect of Bis-Benzimidazole as Lubricant Additive
摘要
Abstract
A new lubricant additive 1,3-bis( 1-tertiary buty1-2-benzimidazy1)-2-thiopropane (tBu-BIMS) was synthesized from o-phenylenediamine, tert-buty1 bromine and 2,2'-thiodiacetic acid. The structure of the product was characterized by means of MS, FTIR and 'H NMR. The corrosion inhibition effect for Q235 steel and the antiwear and antifriction properties of the lubricant additive were evaluated by corrosion test and four-ball test in rapeseed oil. The results showed that tBu-BIMS had good corrosion inhibition effect for Q235 steel in petroleum ether with sulfur of 0. 2 mg/g. When the concentration of the tBu-BIMS was 5 × 10 -5 mol/L, the corrosion inhibition efficiency could reach more than 90%. The lubricant additive could evidently reduce the friction coefficient of rapeseed oil and the wear scar diameters of steel ball. When the mass fraction of tBu-BIMS was 0. 75% , the wear scar diameters could be reduced by 30. 88% .关键词
