Abstract

The effect of the OH groups of the zeolites HY, HZSM-5 and HZSM-11 on the selective behavior of the supported active component P−V−O (P/V=1) in the oxidation of butadiene is characterized in detail and discussed. It was shown that the change in the selectivity was caused by the interaction of the pure component with the protondonor centres of zeolite: on this type of catalysts with the supported active component only furan and not maleic anhydride is formed as a product.

Abstract

Подробно изучено и обсуждено влияние OH-групп в цеолитах HY, HZSM-5 и HZSM-11 на селективные свойства нанесенного активного компонента P−V−O (P/V=1) в реакции окисления бутадиена. Показано, что изменения в селективности обусловлены взаимодействием чистого компонента с протоно-донорными центрами цеолита: на этом типе катализатора с нанесенным активным компонентом в качестве продукта реакции образуется фуран, а не малеиновый ангидрид.
