Procedure

16 g of a strongly acidic ion exchanger (cross-linked polystyrene containing sulfo groups) were suspended in a solution of 160 g of monomethyl adipate prepared according to (c), in 270 g of water. The reaction mixture was heated in a 1 l three-necked flask with an attached spinning band column until no further methanol passed over. The ion exchanger was filtered off; 144.5 g (99% yield) of adipic acid of melting point 153° C. were obtained from the filtrate after crystallization and partial evaporation of the mother liquor.
