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.
本文合成了 2,3-二羟基丁二酸酯(酒石酸酯),并将其用作甲醇-汽油的相稳定剂和饱和蒸汽压抑制剂。结果表明,甲醇-汽油的稳定性取决于酒石酸酯烷氧基的长度。研究发现,几种酒石酸酯在各种汽油-甲醇混合物中均有效,而且酒石酸酯具有很强的降低甲醇-汽油饱和蒸汽压的能力。根据这些结果可以得出结论,酒石酸酯具有成为汽油-甲醇双功能添加剂的巨大潜力。
