Reaction Steps
The procedure of Example 1 was followed except that about 267 grams of DMEA, 300 grams of de-ionized water, and 125 grams of ethylene oxide were used. However, at the end of the nitrogen purge, about 4.5 grams of ethylenediamine were added. The product is a clear and colorless solution, and no color change was observed after one month of standing at room temperature.
