Reaction Steps
Under the conditions specified under (c) 50 parts of oxethylation product (b) are esterified with 10.6 parts of maleic anhydride, whereupon a solution of 13.7 parts of sodium sulfite (anhydrous) in 112 parts of water is added at 70° to 80° C. When the mixture has become clear, it is stirred for a further hour at the same temperature. The amount of water added can vary between 50 and 85% by weight of the final solution.
