通过系统试验，研究了DMC-甲醇汽油互溶性影响因素。结果表明：甲醇汽油中加入DMC可以增强互溶性能，降低相分离温度，φ(DMC)每提高1个百分点，可以使相分离温度降低约3℃；水含量对甲醇汽油的相分离温度影响很大，当配制M15甲醇汽油所用的甲醇原料中的w(H2O)达到0.5%时，只有φ(DMC)不小于3.8%，才可保证其相分离温度低于-40℃。

The factors influencing the miscibility of DMC-methanol-gasoline blends were studied experimentally. The results showed that adding DMC (dimethyl carbonate) to a methanol-gasoline blend could improve the miscibility and reduce the phase separation temperature about 3℃ for every percentage point increase in DMC volume; water content seriously affected the phase separation temperature of the methanol-gasoline blend, when the M15 methanol gasoline was made from the methanol containing a mass fraction of water of 0.5%, it required that the volume fraction of DMC in it was not below 3.8% to ensure the phase separation temperature below-40℃.
