In this paper, 2,3-dihydroxybutanedioic acid esters (tartaric esters) were synthesized and used as phase stabilizer and saturation vapour pressure depressor of methanol-gasoline. The results show that the stabilities of the methanol-gasoline depend on the length of the tartaric esters’ alkoxy group. Several tartaric esters were found to be effective in various gasoline-methanol blends and the tartaric esters display high capacity to depress the saturation vapour pressure of methanol-gasoline. According to the results, it can be concluded that the tartaric esters have the great potential to be bifunctional gasoline-methanol additives.
