Sustainable production of acrylic acid: Rb+- and Cs+-exchanged Beta zeolite catalysts for catalytic gas-phase dehydration of lactic acid

- Gas-phase dehydration of lactic acid over Rb+- and Cs+-exchanged β zeolites is presented.
- Effects of the exchange degrees for Rb+ and Cs+ on the catalyst behavior are uncovered.
- Correlation between the catalyst performance and its acid-base property is given.
