Abstract:
It was shown for the example of ZSM-23 zeolite with Si/Al = 50 that medium-porous zeolites with
MTT structure are effective catalysts for gas-phase isomerization of ethylene into acetaldehyde. At 300–400°C,
a nearly 100% conversion of ethylene oxide is observed, and the selectivity of its conversion to acetaldehyde
exceeds 90%. The main by-products of the reaction are crotonic aldehyde and dioxane. ZSM-23 zeolite exhibits a
higher selectivity and stability as compared with ZSM-5 zeolite having a 3D MFI structure. This zeolite provides
an output of more than 28 g of acetaldehyde per gram of the catalyst per hour.
