ResumoThe use of methanol-gasoline blends as automotive fuel is limited, in part, by phase separation at low temperatures. The separation temperature of these mixtures can be adjusted by varying the percentage of blending agent present. Two blending agents were considered in this study, tertiary butyl alcohol and isopropyl alcohol. Both were found to significantly lower the separation temperature, although, isopropyl alcohol is more effective, possibly due to its greater ability to form hydrogen bonds. Correlation equations were derived relating the percentage compositions and the separation temperature.
