Abstract
Active 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.
Claims25
A process for alkoxylation of organic compounds containing at least one active hydrogen which process comprises reacting said organic compound with an alkylene oxide in the presence of a catalytically effective amount of a salt of a Group Ia or Group IIa element and an oxy acid of at least one element chosen from a Group IVb, Group Vb or Group VIb element or mixtures thereof.
A process for alkoxylation of organic compounds containing at least one active hydrogen which process comprises reacting said organic compound with an alkylene oxide in the presence of a catalytically effective amount of a salt of at least one element chosen from a Group Ia or Group IIa or rare earth element and an oxy acid of at least one element chosen from a Group IVb, Group Vb or Group VIb elements or mixtures thereof.
