Abstract: PROBLEM TO BE SOLVED: To provide a method for producing triethanolamine having more improved color quality compared with the well-known technical level.
SOLUTION: The method for producing triethanolamine includes adding phosphorous and/or hypophosphorous acid and a basic compound before and/or in distillation of triethanolamine, wherein the basic compound is a [R
1 R
2 R
3 (2-hydroxyethyl)ammonium]hydroxide, provided that R
1 , R
2 and R
3 independently represents C
1 -
30 alkyl or C
2 -
10 hydroxyalkyl. The additional addition of ammonium hydroxide to phosphorous acid brings increase of yield by distillation of triethanolamine without disadvantageous influence over color number but with partially-advantageous influence on the color number (in a sense of reduction of the color numbers).
