进入21世纪，随着经济的快速发展，我国的能源消费也不断增长，能源日趋紧张，寻找汽车替代清洁能源已成为我国的一项基本国策，甲醇汽油可作为一种清洁、安全、经济的替代能源加以推广。甲醇是一种高极性化合物，它不能在所有情况下都溶于烃类，低温或遇水就可能引起相分离，形成两层。为了解决这个问题，必须寻找合适的添加剂。在我国北方地区，冬季气温低，若使用普通甲醇汽油，就会导致其分层。要解决这个问题，就必须研究甲醇和汽油的互溶性和抗水性，选择出合适的助溶剂及抗水剂。
本实验中，针对甲醇汽油存在的低温相对稳定性较差及遇水分层问题，选择助溶剂，确定选取助溶剂及其添加量对甲醇汽油分层温度的影响，筛选最佳的助溶剂及添加量。在选取的最佳的助溶剂下，确定所选取抗水剂对甲醇汽油抗水性的影响，并确定最佳的抗水剂及理想添加量。经过实验得出了甲醇汽油的理想助溶剂为MTBE，SW1，SW2的复合助溶剂，调整此助溶剂的配比和添加量，可以使甲醇汽油混合物在较低温度下（<-45℃）作为车用燃料。其最佳配比是：汽油85%，甲醇10%，MTBE 5%，SW1 0.4%，SW2 0.4%（均为体积含量），理想抗水剂为MTBE，其抗水性能为？

Enter 21st century, with the fast development of economy, the energy-consuming of our country is increasing constantly too, have more nervous energies becoming, look for car substitute clean energy become a fundamental state policy of our country already, the petrol of methanol can be popularized as a kind of cleanness, safe, economic alternative energy source. Methanol is a high polar compound, it can't dissolve in all the situations in the hydrocarbons, low temperature or meet water might cause, separate, take shape two layers. In order to solve this problem, must look for the additive suitable. In the northern area of our country, the temperature is low in winter, if use the petrol of ordinary methanol, will cause its each. Solve this problem, necessary research methanol and the dissolving and water-resistance each other of the petrol, choose suitable helping solvents and resisting water pharmaceutical.
In this experiment, the relative stability of low temperature existi
