Total Claims: 4
Claim 1
Independent Claim
81 words
AN ORGAN-METALLIC CYCLIC TITANIUM COMPOUND CONTAINING AT LEAST TWO HETEROCYCLIC RINGS AND HAVING FROM ONE TO FIVE TITANIUM ATOMS IN THE MOLECULE, EACH TITANIUM ATOM FORMING A PART OF TWO ADJACENT RINGS, EACH RING CONSISTING, IN ADDITION TO TITANIUM, OF -O-R-O- GROUPS IN WHICH EACH OXYGEN ATOM IS BONDED DIRECTLY TO TITANIUM BY A PRIMARY VALENCE BOND AND R IS A GROUP CONTAINING ONLY FROM TWO TO THREE ALIPHATIC CARBON ATOMS IN THE CHAIN CONNECTING THE OXYGEN ATOMS, THE NUMBER OF

Claim 3
Independent Claim
113 words
THE METHOD OF MAKING CYCLIC ORGANO-METALLIC TITANIUM COMPOUNDS WHICH COMPRISES REACTING UNDER ANHYDROUS CONDITIONS A LOWER TETRAALKYL TITANATE WITH TWO MOLECULAR PROPORTIONS OF AN ORGANIC COMPOUND CONTAINING ONLY TWO REACTIVE GROUPS CONNECTED TO AN ALIPHATIC CARBON CHAIN IN WHICH SAID GROUPS ARE SPACED APART BY TWO TO THREE CHAIN CARBON ATOMS, THE CARBON ATOMS OF SAID CHAIN BEING BONDED DIRECTLY TO EACH OTHER, SAID REACTIVE GROUPS BEING SELECTED FROM THE CLASS CONSISTING OF HYDROXY GROUPS AND ESTERS OF SUCH GROUPS WITH LOWER ALIPHATIC CARBOXYLIC ACIDS, AND SEPARATING FROM THE REACTION MIXTURE SUBSTANTIALLY FOUR MOLECULAR PROPORTIONS OF A BY-PRODUCT SELECTED FROM THE CLASS CONSISTING OF ALKANOL AND AN ALKYL ESTER OF SAID CARBOXYLIC ACID.
