Abstract (English):
The low- temperature properties of solutions of acetone and traditional oxygenates in hydrocarbons was investigated. Found that the solutions of hydrocarbons at a concentration of oxygenates to 3%., in the presence of 2.5% water, are stable at temperature - 50 ° C. Introduction of aqueous ethanol in the investigated concentrations revealed that acetone and MTBE more effectively reduce the turbidity temperature of the fuel with the share of ethanol in gasoline 2% and C 3-C 4 alcohols are more effective at higher proportions of ethanol. In the study of hydrocarbon – acetone mixtures in the presence of SAS is shown that some of them have a satisfactory solubility at low temperatures.
