Title: (EN) METHOD OF REDUCING COLOR IN ALKANOLAMINE COMPOSITIONS AND COMPOSITIONS PRODUCED THEREBY
Abstract:
(EN)

A method of reducing color in an alkanolamine is described. The method includes contacting the alkanolamine with a color-reducing amount of a borane complex effective to provide a color-reduced alkanolamine composition having a Platinum-Cobalt Color Value, according to Test Method ASTM D1209, of less than 50.
