Procedure

The procedure of Example 1 was followed except that about 356 grams of DMEA, 400 grams of de-ionized water, and 170 grams of ethylene oxide were used. At the end of the nitrogen purge, about 9 grams of aminoethylethanolamine (AEEA) was added. The product is a clear and colorless solution, and no color change was observed after one month of standing at room temperature.
