Reaction Steps

A 5-liter flask, standardly equipped, was charged with 1,064 grams of pentachlorophenol containing about 700 to 800 ppm of aluminum and ferric compounds and 436 grams of dibromopropanol. This mixture was heated to 121°C. and propylene oxide was added up to 138°C. After cooling the mixture to approximately 90°C., 32 grams of triethylamine was added followed by propylene oxide until the mixture gave an acid number of 0.13. The mixture was then stripped for 2 hours at 80° - 87°C./1-2 mm. Hg. The polyol product weighed 2566 grams and had a viscosity of 930 cps at 25.5°C.
