Abstract: A sulfopolyester comprising repeat residue units from the reaction product dimethyl-5-sodiosulfoisophthalate, isophthalic acid, 1,4-cyclohexanedimethanol and diethylene glycol, has at least one property selected from: a) an acidity of greater than 0.030 measured as milliequivalents H+/gram of sulfopolyester; b) a titanium concentration, measured as metal, of less than about 27 ppm, based on the amount of sulfopolyester; or c) an acidity of greater than 0.010 measured as milliequivalents H+/gram of sulfopolyester, a pH of less than 6.0 and a concentration of a base compound of less than 0.0335 moles/kg of sulfopolyester. A method for making the water-dispersible or water-dissipative sulfopolyester of the present invention is disclosed. Aqueous dispersion having from 0.001 to about 35 weight % of the sulfopolyester of the present invention is also disclosed. The sulfopolyester is useful in making hair spray formulations suitable for pump or aerosol spray applicators.

Abstract: A process for recovering a desired organic acid from a solution includes the steps of: providing an aqueous solution including at least one desired organic acid or its acid anion; adjusting the proton concentration in the aqueous solution to a desired level, with the desired proton concentration being selected, at least in part, by the amount of available protons needed to associate with the acid anions of the desired organic acid(s) to be recovered and/or acid anions that are weaker than the desired organic acids; and recovering at least a portion of the at least one desired organic acid from the aqueous phase. The desired proton concentration can be based on the amount of available protons being greater than, less than or substantially equal, to the amount of protons needed to associate with the anion of the desired organic acid(s) and acid anions that are weaker than the desired organic acid(s).
