Claim 1
Independent Claim
115 words
A TITANIUM CHELATE COMPRISING THE REACTION PRODUCT OF A TITANIUM ORTHOESTER HAVING THE FORMULA TI(OR)4 IN WHICH R REPRESENTS AN ALKYL GROUP CONTAINING FROM 2 TO 10 CARBON ATOMS, AN ALKYLENE GLYCOL CONTAINING 2 OH GROUPS IN WHICH EACH ALKYLENE GROUP CONTAINS UP TO 6 CARBON ATOMS, AND AN ALKANOLAMINE SELECTED FROM THE GROUP CONSISTING OF DIETHANOLAMINE,TRIETHANOLAMINE, DIISORPOPANOLAMINE AND TRIISPROPANOLAMINE AND IN WHICH THE RATIO OF THE NUMBER OF MOLES OF SAID GLYCOL PLUS SAID ALKANOLAMINE TO THE NUMBER OF MOLES OF TI IN SAID CHELATE IS FROM 4:1 TO 1:1 AND THE RATIO OF THE NUMBER OF MOLES OF SAID ALKANOLAMINE TO THE NUMBER OF MOLES OF SAID GLYCOL IS FROM 1:5 TO 10:1.
