| Abstract: | The object of the invention is a catalytic composition comprising titanium and phosphorus and resulting from the contacting of at least one titanate with at least one quaternary "onium" salt of an acid selected from the group consisting of phosphoric acid and the phosphonic acids of formula R.sup.7 H.sub.2 PO.sub.3 in which R.sup.7 is a hydrocarbon group having 1 to 38 atoms of carbon and the "onium" remainder is a remainder of formula (R.sup.8 R.sup.9 R.sup.10 R.sup.11 M).sup.+ in which M is an element from the group VA of the periodic table of elements, preferably nitrogen or phosphorous, and R.sup.8, R.sup.9, R.sup.10 and R.sup.11, identical or different, represent each an atom of hydrogen or a hydrocarbon group having 1 to 38 atoms of carbon. This catalytic composition is utilizable for producing asters and polyesters from epoxides and carboxylic acid anhydrides. |

| Claim: | We claim |
| Claim: | 1. A catalytic composition comprising titanium and phosphorus, prepared by a process comprising contacting at least one titanate of formula (I): [equation included] |
| Claim: | in which each one of the R groups independently represents a hydrocarbon group having 1 to 10 atoms of carbon, with at least one quaternary "onium" salt of an acid selected from the group consisting of phosphoric acid of formula H.sub.3 PO.sub.4 and the phosphoric acids of general formula (II): [equation included] |
| Claim: | in which R.sup.7 is a hydrocarbon group having 1 to 38 atoms of carbon, and whose quaternary "onium" remainder is a remainder of formula (III): [equation included] |
| Claim: | in which M is an element from group VA of the periodic table of elements and R.sup.8, R.sup.9, R.sup.10 and R.sup.11, are each independently an atom of hydrogen or a hydrocarbon group, optionally substituted by a hydroxyl group, having 1 to 38 atoms of carbon. |
| Claim: | 2. A composition according to claim 1 wherein the quaternary "onium" remainder is a remainder of general formula (III) in which M represents an atom of nitrogen or of phosphorus. |
| Claim: | 3. A composition according to claim 1 wherein the quaternary "onium" salt is a phosphoric acid salt having per in its molecule 2,3 or 4 atoms from group VA of the periodic table of elements. |
| Claim: | 4. A composition according to claim 1 wherein the quaternary "onium" salt is a phosphonic acid salt of general formula (II) having in its molecule 2 or 3 atoms from group VA of the periodic table of elements. |
| Claim: | 5. A composition according to claim 1, wherein the titanate is a titanate of formula (I) in which each one of the R groups independently represents a linear or branched alkyl group. |
| Claim: | 6. A composition according to claim 1 wherein the titanate is contacted with the quaternary "onium" salt in a liquid medium, for a duration ranging from about 1 to about 60 minutes, at a temperature ranging from about 0.degree. to about 100.degree. C. and with a molar ratio titanate/"onium" salt ranging from about 0.5:1 to about 2:1. |
| Claim: | 7. A composition according to claim 1, wherein the "onium" remainder is tetramethylonium, tetraethylonium, tetrapropylonium, tetrabutylonium, tetraphenylonium, tetrabenzylonium, methyltributylonium, methyltriethylonium, methyltriphenylonium, butyltriphenylonium, ethyltriphenylonium, benzyltrimethylonium, benzyltributylonium, benzyltriphenylonium, phenyltrimethylonium, octadecyltrimethylonium, naphtyltrimethylonium, tolyltrimethylonium, dimethyldioctadecylonium, dimethyldihexadecylonium, dioctadecylhydroxyethylmethylonium, decylhydroxypropylmethylonium or tricaprylylmethylonium. |
| Claim: | 8. A composition according to claim 1, wherein the R groups are independently methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tertiobutyl, and 1-methyl propyl. |
