For the esterification of methanol and acetic acid to methyl
acetate, the heterogeneous microporous H-Ferrierite which
possessing a stable Brønsted acid sites after phospho-
rous modification was found to be one of the candidates
for obtaining a higher catalytic activity and stability. The
improved methanol conversion and selectivity to methyl
acetate at steady-state after P-modification of H-Ferrierite
is mainly attributed to the proper suppression of the strong
Brønsted acid sites on the H-Ferrierite with the simulta-
neously increased stability of Brønsted acid sites at higher
temperature. From the good correlation of catalytic activity
at steady-state with the results of adsorbed pyridine FT-IR
(ratio of Brønsted acid sites to total acid sites) on the as-
prepared catalysts, the measurement of Brønsted acid site
stability through FT-IR analysis of adsorbed pyridine at
different desorption temperatures seems to be a proper and
simple method to explain the steady-state activity by just
using the acidic properties of the as-prepared H-Ferrierite
catalysts for esterification of methanol.
