Dehydration of methyl {alpha}-hydroxyisobutyrate catalyzed by zeolites
- Univ. of Texas, Richardson, TX (United States)
The catalytic dehydration of methyl {alpha}-hyroxyisobutyrate over various zeolites in a flow reactor is described. Both NaY and NaX are effective catalysts for the selective conversion of MOB to methyl methacrylate. Modification with K{sup +} and Cs{sup +} enhances the activity and selectivity of NaY but renders NaX a less effective catalyst. Acidic zeolites (HY, Beta, GdNaX, SmNaY, fluorinated SmNaY) were shown to be quite active but poorly selective with catalyst deactivation resulting from coke formation. 26 refs., 7 figs., 2 tabs.
