In this paper, hydroxyacetic acid esters (glycolic esters) were synthesized and used as phase stabilizer and saturation vapour pressure depressor of methanol-gasoline. The results show that the stabilities of the blends depend on the length of the glycolic esters’ alkoxy group. Among these glycolic esters, hexyl glycolic ester and octyl glycolic ester were found to be the most effective in various gasoline-methanol blends. Besides, the glycolic esters display high capacity to depress the saturation vapour pressure of methanol-gasoline and decyl glycolic ester is the most effective one. According to the results, it can be concluded that the glycolic esters have the great potential to be used as bifunctional gasoline-methanol additives.
本文中,羟基乙酸酯(甘醇酸酯)被合成并作为甲醇-汽油的相稳定剂和饱和蒸汽压降低剂。结果显示,混合物的稳定性取决于甘醇酸酯的烷氧基链长度。在这些甘醇酸酯中,己基甘醇酸酯和辛基甘醇酸酯在各种甲醇-汽油混合物中效果最为显著。此外,甘醇酸酯展现了降低甲醇-汽油饱和蒸汽压的高能力,其中癸基甘醇酸酯效果最为有效。根据这些结果,可以得出结论,甘醇酸酯具有作为双功能甲醇-汽油添加剂的巨大潜力。
