Abstract: |
The stability of methanol gasoline of different proportion in the presence of water and under low temperature were studied by using cat gasoline as starting material. In addition, the mechanism of separation of methanol from gasoline was discussed. The results showed that the stability of methanol gasoline increased with the increasing of methanol content. The more the content of latent solvent was, the lower the temperature of phase disengagement was. The adding volume of straight chain alcohol decreased with the increasing of carbon numbers and reduction of HLB value, in which, the adding volume of n-octyl alcohol was the least. When the water content of M30 and M50 were 1%, the needing content of n-octyl alcohol was 5% and 2%, respectively. When the content of n-octyl alcohol was 3%, the temperature of phase disengagement were lower than -20 ℃.
