PP-I-56The experiments and simulation have shown, that main products of oxidativeconversion are hydroxyl and carbonyl compounds (RH:O 2 =1:2, table 1) and longchainHC of isomer structure for propane-butane mix. Respective end productconcentrations obtained in experiments are shown in the table 1.A leading role for oxygenated HC formation is played by the reaction ofdisproportionation of peroxide radicals:2ROO˙ → ROH + RC(-H)O + O 2 .In our conditions it represents chain termination process which results information of alcohols, aldehydes and ketones. Isomer HC formation occurred inoxygen deprived C 3 -C 4 mix predominantly via recombination of alkyl radicals.Table 1. Composition of oxygenated HC (experiment).ProductsConcentrations, % massaldehydes 31,1ketones 17,1alcohols 51,8The results obtained indicate that light hydrocarbons C 3 -C 4 could be efficientlytransformed to liquid oxygenated products via short-chain reaction mechanism.Compositions of the end products derived from numerical calculations have a goodagreement with experimental data.319
