Abstract: Off-color N-(C₄-C₁₀)alkyl di(C₂-C₃) alkanolamines purified and decolorized by vacuum distillation at a pressure within the range of 1 to 50 mm.Hg (1-50 torr) in the presence of water and or water-soluble metal borohydride whereby the distilled alkanolamine has a reduced APHA color rating which is maintained on storage.

Abstract: A method is disclosed to prepare a uniform, stable dispersion of an additive amount of a water-insoluble, high viscosity liquid polyalkylene glycol derivative in a substantially nonaqueous, water-soluble alkanolamine by combining under pressure a proportionate amount of the total polyglycol derivative to be added to the alkanolamine component, or mixture of alkanolamine and polyglycol derivative, subjecting the mixture to shear stress, and repeating the procedure until a uniform, colloidal dispersion is obtained of the alkanolamine containing the desired additive amount of polyglycol derivative.
