Abstract

The present disclosure provides, in part, a solvent compound for use as a substitute for a glycol ether, an alkyl ether of diethylene glycol, ethylene glycol or propylene glycol.

Claims (21)

1. A method of reducing an amount of volatile organic components in a composition, the method comprising:

replacing at least a portion of a glycol ether, or an alkyl ether of diethylene glycol, ethylene glycol or propylene glycol in the composition with a compound of Formula (I):

wherein R is C 1-12 alkyl, optionally substituted from one up to the maximum number of substituents with oxygen.

2. The method of claim 1 , wherein the replacing comprises replacing a glycol ether with the compound of Formula (I).

3. The method of claim 1 , wherein the replacing comprises replacing a propylene glycol with the compound of Formula (I).

4. The method of claim 1 , wherein the compound of Formula (I) is:

5. The method of claim 1 , wherein the compound of Formula (I) is:

6. The method of claim 1 , wherein the composition comprises a paint, coating or oil dispersant.

7. The method of claim 1 , wherein the composition comprises a pharmaceutical, nutritional, dietary or cosmetic product, and the compound of Formula (I) is an excipient.

8. The method of claim 1 , wherein the compound of Formula (I) is a carrier of an active ingredient in the composition.

9. The method of claim 1 , wherein the composition is a cleaning solvent, a reactive solvent, co-solvent, dispersant, wetting agent, coupling agent, stabilizer, chemical intermediate, coalescent, or viscosity reduction solvent.

10. The method of claim 1 , wherein the compound of Formula (I) is a coupling agent in the composition.

11. The method of claim 1 , wherein the compound of Formula (I) is a solvent, co-solvent or coalescent, and the composition is a water borne alkyd, conventional lacquer, dye, stain, latex, acrylic, alkyd, architectural paint and/or coatings formulation.

12. The method of claim 1 , wherein the composition is a cleaning and/or degreasing formulation, and the composition further comprises a surfactant.

13. The method of claim 1 , wherein the compound of Formula (I) is an intermediate in a chemical reaction.

14. The method of claim 2 , wherein the compound of Formula (I) is:

15. The method of claim 2 , wherein the compound of Formula (I) is:

16. The method of claim 3 , wherein the compound of Formula (I) is:

17. The method of claim 3 , wherein the compound of Formula (I) is:

18. The method of claim 9 , wherein the compound of Formula (I) is:

19. The method of claim 9 , wherein the compound of Formula (I) is:
