Abstract: A novel, salt-free monoamphopropionate amphoteric surfactant is prepared in yields of from 75% to 80%, from a reaction comprising an imidazoline and a mixture of acrylic acid and sodium acrylate in an aqueous medium. The acrylic acid/sodium acrylate mixture is comprised of the two components in a range of molar ratios of from about 1:6 to about 1:3, respectively, and by replacing methyl acrylate, the reaction does away with the production of methanol which is an unwanted, hazardous and toxic byproduct. The imidazoline reacts in amounts in excess of 90% resulting in the highly pure yields and any left over unreacted acrylic acid can be easily removed by treating it with sodium bisulfate.

Abstract: Contaminated aqueous systems can be cleaned using an ultra-filtration system that allows for high recovery yields of the surfactant employed therein for recycle and reuse. The system employs specific nonionic surfactants which remain polar and solvated at the higher operating temperatures of the system. The surfactant/contaminant containing aqueous system is ultra-filtered resulting in the surfactant passing through with the permeate at extremely high yields for recovery and reuse.

Abstract: Contaminated aqueous systems can be cleaned using an ultra-filtration process that allows for the recovery of high yields of the surfactant employed therein for recycle and reuse. The system employs a specific class of sugar-derived nonionic surfactants which remain polar and solvated at the higher operating temperatures of the system. Specifically, these are sugar-derived nonionic surfactants more definitively known as the alkyl polyglycosides and the alkyl glucomides. The surfactant/contaminant-containing aqueous system is ultra-filtered resulting in the surfactant passing through with the permeate at extremely high yields for recovery and reuse.

Abstract: A process of preparing a concentrate which is useful as a thickener for aqueous compositions is provided. The process comprises obtaining a solution of an associative thickener compound in an organic solvent capable of forming a low boiling azeotrope with water. The solution is essentially free of water at this point and is at a temperature above the boiling point of said low boiling azeotrope. Water is added to said solution and an azeotrope of water and said organic solvent is distilled. The rate of addition of water is sufficient to replace said azeotrope with water, but is insufficient to cause a second phase to form in the resulting mixture of said solution and said water. The process yields a concentrate of an associative thickener in water, which concentrate is essentially free of volatile organic solvents.
