Reaction Steps

A 1-liter flask, standardly equipped, was charged with 90 grams of dextrose and 85.2 grams of triphenylphosphite and heated to 140° C. 266 grams of pentachlorophenol containing about 750 ppm aluminum and iron compounds was added. Then propylene oxide was added dropwise with stirring at up to 150° C. After cooling, 4.5 grams of triethylamine was added and oxypropylation continued until the acid number was 0.3. The mixture was then stripped for 3 hours at 84°-88° C./1 mm. Hg. The 689 grams of oxypropylated product had the following properties.
