PP-II-28to 31 % in catalyzate was observed at reduction of propane-butane in reaction mixture. Thedetermination of the product composition showed that the process follows a complexmechanism including oxidation, oxidative dehydrogenation, and cracking.Modification of carrier by zeolite ZSM-5 in the presence of aluminium oxinitratepromoted increase the content of acetone in catalyzate up to 70-80 %, but decreased thecontent of acetaldehyde, Fig.1. The content of acetone was higher the whole temperatureinterval.Content in catalyzate, %90807060504030201002413350 400 450 500T e m p e r a t u r e, o CFig.1 – Influence of the temperature on content of acetone in catalyzate at oxidation ofpropane-butane mixture.
