Vr. Choudhary et al., Highly selective Si-MCM-41 supported InCl3, GaCl3, FeCl3 and ZnCl2 catalysts for low temperature esterification of tert-butanol by acetic anhydride, MICROP M M, 47(2-3), 2001, pp. 179-183
Si-MCM-41 supported InCl3, GaCl3, FeCl3 and ZnCl2 catalysts (metal chloride
loading = 1.1 mmol g(-1)) have very small activity for the dehydration of
tert-butanol and hence show very high selectivity (> 99%) for the esterific
ation of tert-butanol by acetic anhydride, producing acetic acid as a by-pr
oduct, at less than or equal to 50 degreesC. The esterification activity of
the supported metal chloride catalysts is in the following order: InCl3 >
GaCl3 > ZnCl2 > FeCl3. (C) 2001 Elsevier Science B.V. All rights reserved.
