Procedure

To a 500 ml three neck flask fitted with a reflux condenser and dropping funnel is added 131.2 grams (1.12 moles) 70% phosphorous acid and 207.2 grams (2.1 moles) 37% hydrochloric acid. Aminoethyl ethanolamine, 42.1 grams (0.40 mole) is then added dropwise while stirring. The mixture is then heated to reflux and 97.3 grams (1.2 moles) 37% aqueous formaldehyde is added dropwise during 1 hour. Reflux is continued for 2 hours after completion of the formaldehyde addition. The mixture is then cooled and bottled.
