METHODS OF THE ANALYSIS OF FRACTIONAL COMPOSITION OF GASOLINES WITH OXYGEN-CONTAINING COMPONENTS
Problems of the analysis of fractional structure the azeotrope of mixes are considered. Relevance of work is that recently in the world production of biofuel and the biofuel of additives in the existing types of fuel, in particular ethanol in gasoline increases. As the rule, it is accompanied by emergence of a number of difficulties in the analysis of quality of fuel mixes as petrol fractions in connection with alcohols form azeotrope mix. Features of distillation the azeotrope of mixes of gasoline from an ethanol of a gepnan with ethanol are studied. The technique of definition of fractional composition of biofuel mixes is developed. Advantage is shown of the analysis the azeotrope of mixes on the device of a micro distillation (PMD-100). As gasoline represents complex hydrocarbonic mix, for a detailed research binary mix of a geptan with ethanol has been chosen. For definition of dependences of temperatures of boiling the hydrocarbonic mixes of mixes from concentration of ethanol was and binary mixes of a geptan with ethanol, with various initial concentration of ethanol are taken in mixes and their fractional distillation on devices of microdistillation and standard distillation is made (AD86 5G and Optidist).
