Procedure
In a preferred embodiment, diethanol amine is charged to the reaction vessel in a substantially equal molar quantity to a 54 percent aqueous solution the sodium salt of isethionic acid. The reactants then are heated to a temperature of about 200° F. at ambient temperature for a sufficient period of time to separate about 38 percent by weight of the reactants as water in the cold finger trap. The bis-hydroxyethylaminoethane sulfonic acid which is produced in about a 100 percent yield is diluted to about a 50 percent solution by the addition of water.
Workup
