Phase stabilizer and methanol gasoline added with phase stabilizer

The invention belongs to the technical field of chemical industry and particularly discloses a phase stabilizer and methanol gasoline added with the phase stabilizer. The phase stabilizer is alkyleneoxide compounds. The methanol gasoline added with the phase stabilizer consists of 30 to 70 mass percent of gasoline, 20 to 60 mass percent of methanol, 5 to 15 mass percent of phase stabilizer, 0.5 to 5 mass percent of preservative and 0.5 to 5 mass percent of cleaning agent. According to the methanol gasoline, the adding amount of the methanol is 20 to 60 percent; and the problems that the methanol gasoline is easy to demix after absorbing water and the methanol and the gasoline are separated at low temperature are effectively solved while the proportion of the methanol is improved as far as possible.
