참여 물질

반응 단계

With stirring, 100.2 g (1 mol) of butyl oxirane, 114 g (0.5 mol) of bisphenol A and 2.14 g of benzyltrimethylammonium bromide are heated to 110° C. When the exothermic reaction has subsided (rise in temperature to 115° C.), the reaction is further stirred at 110° C. until the epoxy value is less than 0.1 eq/kg (16 h). 85.52 g (0.2 mol) of the resultant reaction product are reacted with 296 g (3.2 mol) of epichlorohydrin and 1.32 g of tetramethylammonium bromide according to the method described in EP-A 22 073. After addition of 33.6 g (0.42 mol) of 50% aqueous sodium hydroxide and removal of the water under vacuum, the product is isolated and dried.
