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.

in one homologous series. These parameters were taken as constant for each series of esters of the corresponding acids. The dynamic viscosity–temperature dependence of esters was better described by the VFT model than the Arrhenius-like equation. The capabilities of some group-additivity methods for predicting density have been reviewed and compared with experimental results.
