Reaction Steps

Into a 500 ml 3-neck flask was weighed 22.8 grams (0.100 mole) of para bisphenol A, 8.0 grams (0.200 mole) of sodium hydroxide and 208 grams (11.56 moles) of water. The mixture was agitated under a nitrogen purge until complete solution had occurred. Into this mixture was charged a solution of varying amounts of 1,3-di-chloro-2-propanol in 185 grams (2 moles) of epichlorohydrin. The mixture was then agitated for exactly one hour (3600 s) at a controlled temperature of 30° C. After this time, samples were withdrawn for analysis. The amount of bisphenol A which had been converted (phenolic OH conversion) was determined by ultraviolet spectrophotometer. The amount of diglycidyl ether and glycidol which had been formed in the reaction was determined by gas chromatography analysis. The amount of glycerine which had been formed in the reaction was determined by liquid chromatography analysis. The yield of product based on the amount of epichlorohydrin converted was determined from the phenolic OH conversion and the amounts of the above by-products which were formed from the epichlorohydrin. Ths is reported as the % yield based on epichlorohydrin. The results of these experiments are shown in the following Table.
