Claims
- 1. In a process for the formation of two terminal carboxylic acid groups from a mixture comprising an ozonide having from about 8 to about 30 carbon atoms by contacting a mixture comprising at least one of the ozonide or oxidizable ozonide scission products with oxygen at a temperature of from about 50.degree. C. to about 150.degree. C. with an oxygen-containing gas, the improvement which comprises: contacting an agitated liquid mixture comprising at least one of the ozonide or the oxidizable ozonide scission products with an oxygen containing gas in the form of bubbles with a diameter of from 25 to 100 microns.
- 2. In a process for the formation of two terminal carboxylic acid groups from a mixture comprising an ozonide having from about 8 to about 30 carbon atoms by contacting a mixture comprising at least one of the ozonide or oxidizable ozonide scission products with oxygen at a temperature of from about 50.degree. C. to about 150.degree. C. with an oxygen-containing gas, the improvement which comprises: contacting an agitated liquid mixture comprising at least one of the ozonide or the oxidizable ozonide scission products with an oxygen containing gas in the form of bubbles with a diameter of less than 25 microns.
- 3. The process of claim 1 wherein the bubbles have a diameter less than 10 microns.
- 4. The process of claim 1 wherein the mixture is heated while contacting the oxygen containing gas.
- 5. The process of claim 2 wherein the mixture is heated while contacting the oxygen containing gas.
- 6. The process of claim 3 wherein the mixture is heated while contacting the oxygen containing gas.
- 7. The process of claim 4 wherein the mixture comprises a catalyst effective for oxidation of the ozonide scission products.
- 8. The process of claim 7 wherein the catalyst comprises manganese.
- 9. The process of claim 5 wherein the mixture comprises a catalyst effective for oxidation of the ozonide scission products.
- 10. The process of claim 9 wherein the catalyst comprises manganese.
- 11. The process of claim 6 wherein the mixture comprises a catalyst effective for oxidation of the ozonide scission products.
- 12. The process of claim 11 wherein the catalyst comprises manganese.
- 13. The process of claim 1 wherein the bubbles are formed by a method selected from the group consisting of passing the gas through a porous substrate, dissolving the gas in the mixture under an elevated pressure then reducing the pressure and by mechanical means.
- 14. The process of claim 2 wherein the bubbles are formed by a method selected from the group consisting of passing the gas through a porous substrate, dissolving the gas in the mixture under an elevated pressure then reducing the pressure and by mechanical means.
- 15. The process of claim 3 wherein the bubbles are formed by a method selected from the group consisting of passing the gas through a porous substrate, dissolving the gas in the mixture under an elevated pressure then reducing the pressure and by mechanical means.
- 16. The process of claim 4 wherein the bubbles are formed by a method selected from the group consisting of passing the gas through a porous substrate, dissolving the gas in the mixture under an elevated pressure then reducing the pressure and by mechanical means.
- 17. The process of claim 5 wherein the bubbles are formed by a method selected from the group consisting of passing the gas through a porous substrate, dissolving the gas in the mixture under an elevated pressure then reducing the pressure and by mechanical means.
- 18. The process of claim 6 wherein the bubbles are formed by a method selected from the group consisting of passing the gas through a porous substrate, dissolving the gas in the mixture under an elevated pressure then reducing the pressure and by mechanical means.
- 19. The process of claim 8 wherein the bubbles are formed by a method selected from the group consisting of passing the gas through a porous substrate, dissolving the gas in the mixture under an elevated pressure then reducing the pressure and by mechanical means.
- 20. The process of claim 10 wherein the bubbles are formed by a method selected from the group consisting of passing the gas through a porous substrate, dissolving the gas in the mixture under an elevated pressure then reducing the pressure and by mechanical means.
