Summary
Experimental work was done to relate selected physical properties of gasoline/methanol solutions, containing contaminant levels of water, to compositional and physical properties of the blending gasoline. Water tolerance, octane number, vapor pressure, and distillation data are presented for eight gasolines and for their methanol solutions at methanol levels up to 20 wt-pct. The water tolerances of these fuels were strongly dependent upon temperature, methanol concentration, and gasoline composition. To cover a wider range of compositional effects, water tolerance measurements were made at selected methanol levels on a variety of individual hydrocarbons, refinery stocks, and gasolines selected for specific compositional characteristics. These selections provided a sufficient range of property variation for the data to permit useful water-tolerance/gasoline composition correlations. The results presented in this report supplement and expand published data on water tolerances of gasoline/methanol mixtures. It is shown that an estimate can be made of the water tolerance of a gasoline/methanol mixture when the composition of the gasoline is known in sufficient detail. Portions of the D-86 distillation curves of gasoline/methanol mixtures can be estimated from a knowledge of the base gasoline distillation curves. In the region of 5 to 20 pct methanol content, vapor pressures can be estimated from those of the gasolines. The blending octane numbers resulting from the study agree well with previously published values. The referenced material and their associated bibliographies are intended to serve as a source of information regarding previous work on methanol and methanol/gasoline solutions for use as automotive fuel.
