PCT No. PCT/AU93/00174 Sec. 371 Date Feb. 13, 1995 Sec. 102(e) Date Feb. 13, 1995 PCT Filed Apr. 23, 1993 PCT Pub. No. WO93/22266 PCT Pub. Date Nov. 11, 1993Active hydrogen containing organic compounds, for example alcohols, thiols, phenols, thiophenols, carboxylic acids, amides and amines, are alkoxylated, for example, ethoxylated, using catalysts comprising a salt of a Group IIa or Group Ia element and an oxyacid of at least one element chosen from Group IVb, Group Vb or Group VIb, for example, lanthanum titanate, barium titanium, barium strontium titanate, yttrium titanate, lanthanum zirconate, barium zirconate, lanthanum hafnate, barium strontium titanate zirconate and neodymium titanate. The catalyst provide narrow distribution of alkoxylation species and efficient reaction rates.
