Conditions

Temperature: 80 °C

Procedure

A 5-liter flask, standardly equipped, was charged with 1596 grams of pentachlorophenol containing about 750 ppm of aluminum and iron compounds, 680 grams of pentaerythritol and a mixture of 195 grams of triethylphosphite and 260 grams of triphenylphosphite that had been heated overnight at 80° C. Then propylene oxide was added until the acid number was less than 1. The mixture was stripped for 2 hours at 90°-104° C./2-4 mm. Hg. The 3562 grams of oxypropylated polyol product contained a finely divided solid. Upon filtering and washing thoroughly with acetone, approximately 75 grams of the dried solid material was obtained. A sample of the oxypropylated polyol product analyzed as follows:
