perature range corresponding to the kinetic control
of methanol conversion, the activity of the phos-
phate NaZr2(PO4)3 is twice that of CsZr2(PO4)3.
This can be accounted for by the fact that cations of
alkali metals affect the electron density on oxygen
atoms bound to zirconium atoms, thereby chang-
ing their electropositive and, consequently, acid prop-
erties.

The catalysts under study can compete with in-
dustrial catalysts for methanol dehydration. For ex-
ample, the dehydration of methanol in a flow-through
reactor on synthetic aluminosilicates was studied in
[17]. The authors of that study used for comparison
a commercial catalyst DME-FCAT. Comparison of
the catalytic activities and methanol conversions at
the same temperature for the samples we studied,
aluminosilicates examined in [17], and commercial
catalysts DME-FCAT suggests that the phosphates
Zr3(PO4)4 and NaZr2(PO4)3 possess a higher output
capacity, because they can provide higher, nearly
equilibrium degrees of conversion at a 2 10 times
greater load on the catalyst.
