A process for the catalytic hydrolysis of alkylene oxide to alkylene glycol using a hydrothermally stable, mixed metal framework catalyst composition selected from(a) material having the formulaM.sub.x.sup.2+ Q.sub.y.sup.3+ (OH) 2x+3y-nz A.sub.z.sup.n-. a 1 H.sub.2 O (I) wherein M is at least one divalent metal cation; Q is at least one trivalent metal cation; and A is at least one anion providing a valence (n.sup.31), wherein n is at least 1, and wherein a is a positive number, M, Q, and A are provided in a proportion such that x/y is a number equal to or greater than 1, z has a value greater than zero and 2x+3y-nz is a positive number, and M, Q and A are selected to provide a layered structure, and(b) material prepared by calcining the material of formula (I) having the formulaM.sub.x.sup.2+ Q.sub.y.sup.3+ (O).sub.(2x+3y-nz)/2D.sub.z.sup.n-(II) wherein M, Q, x, y, z and n have the same meanings defined above in connection with formula (I) and D is at least one nonvolatile anion.
