Reaction Steps
The reaction is carried out substantially as described in Example 5, initially giving 1165 g (100% of theory) of the desired hemiester as a pale yellow solid with an acid value of 5.27 equivalents/kg from the reaction of 888.7 g (6 mol) of phthalic anhydride and 276.3 g (3 mol) of glycerol in 960 g of methyl isobutyl ketone. Then 450 g (2.37 equivalents) of this hemiester are reacted using 2193 g (23.7 mol) of epichlorohydrin, 208.6 g of a 50% aqueous solution of sodium hydroxide and two times 21 g of a 50% aqueous solution of tetramethylammonium chloride, to give 509.4 g (86% of theory) of the desired yellow viscous product having an epoxy value of 3.38 equivalents/kg (85% of theory) and a chlorine content of 1.4%.
