Procedure

The procedure of Example 1 for the reparation of bis-(2-hydroxyethyl) dimethyl ammonium hydroxide was followed, except that about 357 grams of methyl diethanolamine (MDEA) was used instead of DMEA, 489 grams of de-ionized water, and 115 grams of ethylene oxide were used. The product is a clear and colorless solution. However, after about four days of standing at room temperature, the product darkened somewhat.
