Abstract
A composition has an empirical formula M (glycerol) a (X) b, where M represents a metal atom selected from titanium, zirconium, hafnium or aluminium, X is a ligand derived from acetylacetone or a peroxo ion; a is a number between 1 and 2. 5; b is a number in the range from 1 to 2. An alternative composition results from the reaction of a compound of titanium, zirconium, hafnium or aluminium with (a) glycerol and (b) either: (i) acetylacetone or (ii) hydrogen peroxide, an inorganic base and water. The composition is useful in applications requiring water-stable metal chelates, particularly as a catalyst for esterification and polyurethane reactions.
