<p>PURPOSE:To raise concentration of catalyst, to prevent deactivation of catalytic activity and to produce acetic acid or methyl acetate by one-stage reaction from methanol. CONSTITUTION:Methanol is reacted in the presence of a solid catalyst in a vapor phase to produce acetic acid or methyl acetate. The solid catalyst includes an anion of anion exchanger and a heterocyclic polynuclear compound of Ru-Sn. The heterocyclic polynuclear compound of Ru-Sn includes a complex of the formula [Ru(SnX3)6].Z, [Ru(SnX3)5(PR<a>3].Z and [RuSnX3)6(R<b>CN)].Z [in the formula, X is halogen atom, R<a> is phenyl group, R<b> is methyl group, etc., and Z is counter cation].</p> |
