Stabilization of methanol-containing gasolines
In other countries, methanol is used quite extensively as a component of automotive gasolines. The possibility of using methanol-containing gasolines in this country is currently under investigation. One of the basic problems in using such gasolines is their separation into phases at low temperatures when even traces of water are present. The temperature at which layer separation occurs can be lowered by the use of stabilizers such as isopropanol, isobutanol, 2-ethylhexanol, and other lower alcohols. The considerable difference between gasoline and methanol in physicochemical properties makes it necessary to use stabilizers in large amounts, up to 50% of the methanol content. The cost of stabilizers (C{sub 3}-C{sub 8} alcohols) is more than an order of magnitude higher than the cost of gasoline, and the availability of such alcohols in this country is quite limited. Because of this situation, it is of definite interest to develop new, effective stabilizers. The curtailment of oil production in this country has created a need for alternative fuels, including automotive gasolines. One possibility is the use of stabilized hydrocarbon-methanol blends (HMBs) based on waste materials from certain large-scale petrochemical production operations.
