Abstract: Six kinds of alkylbenzene sulfonic acids are selected to produce sulfonate S1-S6, and sulfonate S3,S4,S6 could be transformed into grease with good performance in comparison with grease produced from commercial sulfonate T106-1 and T106-2. Optimized synthesis conditions of sulfonate S3,S4,S6 are explored by different dosage of methanol,water and type of copromoters, it has been found that good synthesis conditions of sulfonate S3 covers; dosage of methanol of 16%, dosage of water of 4% and dosage of copromoter A of 2%, good synthesis conditions of sulfonate S4 covers;dosage of methanol of 24%, dosage of water of 4% and dosage of copromoter B of 2%, the optimized synthesis conditions of sulfonate S6 covers; dosage of methanol of 8%, dosage of water of 4% and dosage of copromoter B of 2%. Sulfonate S3,S4,S6 produced by optimization conditions exhibit high TBN, good antiwaer property than previous products. Grease G9,G10,G11 produced by new sulfonate S3,S4,S6 exhibit good grease transformation property, low viscosity, improved water stability and high temperature performance.
