    Description / Table of Contents: Abstract Импульсным микрокаталитическим методом в установках проточного типа с неподвижным и вибровзвешенным слоем катализатора изучен механизм окисления н-бутана на α-VOPO4. Установлено равенство скоростей катализа и восстановления, свидетельствующее об окислтельно-восстаовительном механизме преврщения бутана и образования малеинового ангидрида. Показано, что в процессе катализа продкты реакции образуются, в основном, зт счет кислорда катализатора и происходит восстановление α-VOPO4 в (VO)2P2O7.
    Notes: Abstract Mechanism of n-butane oxidation of α-VOPO4 has been studied in pulse fixed and vibrofluidized catalyst bed reactors by the pulse microcatalytic method. It has been established that the rates of catalysis and reduction are similar, which indicates a reduction-oxidation mechanism for butane conversion and maleic anhydride formation. In the course of catalysis the reaction products are formed largely at the expense of catalyst oxygen and α-VOPO4 reduces to (VO)2P2O7.

    Description / Table of Contents: Abstract The specific activity and selectivity of (VO)2P2O7 in the oxidation of n-butane into maleic anhydride were found to be higher than those of α-VOPO4. The important role of the (VO)2P2O7 crystal structure in mild oxidation of hydrocarbons is discussed.
    Notes: Abstract При исследовании окисления н-бутана на α-VOPO4 и (VO)2P2O7 установлена большая удельная каталитическая активность пирофосфата ванадила по сравнению с ортофосфатом. Выдвинуто предположение об осовой роли кристаллической структуры пирофосфата ванадила для селективного окисления углеводородов.
