Abstract: The production of motor fuels from renewable sources is one of the most important areas of development of the world fuel industry. Primary butyl alcohols produced from plant raw materials are currently being used as motor fuels or additives thereto. Modern biochemical methods make it possible to obtain 2-butanol from renewable raw materials in addition to natural butyl alcohols. At the same time, higher characteristics of 2-butanlol than those of primary alcohols determine prospects for its use as motor fuels. Using of 2-butanol as high-octane additives to fuels for spark ignition engines allows to reduce emissions of carbon oxides, but at the same time formation mono - and multifunctional oxygen-containing products as a result of incomplete combustion of fuel is possible. The pathway and composition of the products which are formed during oxidizing transformations of alcohol in internal combustion engines are determined by a ratio of activation energies of reactions the peroxyl radicals with CH-bonds of 2-butanol. Activation energies of reactions of the hydroperoxyl radical with CH-bonds of 2-butanol are estimated with application of calculation methods and primary ways of transformation of 2-butanol are determined. The ways of reactions of oxidation of 2-butanol are necessary for development of kinetic models of such reactionsc.
