Claims
- 1. A method for the treatment of waste-water, which comprises: reacting a polyetheramine and a multifunctional epoxide in waste-water composition that initially is in the form of an emulsion to form a reaction product that causes the emulsion to break into a water phase and an oil phase.
- 2. The method of claim 1 wherein the method includes separating the water phase from the oil phase after the emulsion has been broken.
- 3. The method of claim 1 wherein the multifunctional epoxide has a functionality of from 2to 12.
- 4. The method of claim 1 wherein the multifunctional epoxide has a functionality of from 2 to 6.
- 5. The method of claim 1 wherein the emulsion is maintained at a of temperature from about 20 degrees Centigrade to about 100 degrees Centigrade as the emulsion is being broken.
- 6. The method of claim 1, wherein the multifunctional epoxide is of formula: wherein n is from 1 to 4.
- 7. A method for the treatment of waste-water, which comprises: adding a multifunctional epoxide to a waste-water composition initially in the form of an emulsion and that contains a polyetheramine such that the multifunctional epoxide and the polyetheramine react to form a reaction product, wherein the amounts of epoxide and polyetheramine are used in a quantity sufficient to form an amount of reaction product effective to cause the emulsion to separate into a water phase and an oil phase.
- 8. The method of claim 7 wherein the method includes separating the water phase from the oil phase.
- 9. The method of claim 7 wherein the multifunctional epoxide has a functionality of from 2 to 12.
- 10. The method of claim 7 wherein the multifunctional epoxide has a functionality of from 2to6.
- 11. The method of claim 7 wherein the emulsion is maintained at a of temperature from about 20 degrees Centigrade to about 100 degrees Centigrade as the emulsion is being broken.
- 12. The method of claim 7 further comprising physically separating the oil phase from the water phase.
- 13. The method of claim 7, wherein the multifunctional epoxide is of formula: wherein n is from 1 to 4.
