Disclosed is a method for producing a titanium containing catalyst, wherein the catalyst includes one or more titanium alpha-hydroxy carboxylate species, e.g., titanium citrate, and one or more titanium oxide species, e.g., TiO, wherein x is greater than 0 and less than or equal to 2, wherein the sum of all of the above titanium oxide species relative to the sum of all titanium alpha-hydroxy carboxylate species in the titanium containing catalyst is greater than 0 but less than 1.00 mol.-%. The method of production involves, for example, reacting tetraisopropyl orthotitanate with an aqueous solution of citric acid, and removing the byproduct of 2-propanol by distillation. Also disclosed is a method for the production of polyesters by the use of the catalyst.

Method for the production of a titanium containing catalyst, titanium containing catalyst, method for the production of polyester and polyester

A method of manufacturing a polyurethane compound comprises mixing together a polyol, a polyisocyanate compound and a catalyst and allowing the mixture to cure to form a polyurethane, and is characterized in that the catalyst is a neutral complex of a metal selected from Ti, Zr, Hf, Al, Fe, Bi or Sn and a multidentate organic ligand having: a) a number of anionic donor sites=x; b) a number of neutral donor sites, capable of forming a co-ordinate bond with the metal, =y; c) where x+y=from 5 to 8; d) x is from 2 to 4; e) the ligand molecule is of a size and conformation to enable each of the anionic donor sites and neutral donor sites to form a bond with the same metal atom.
