HCID 14401594HCID 14401594, compound

Procedure

66.8 g (0.2 mol) of 2,2-bis-(3-aminophenyl)hexafluoropropane are dissolved in 250 ml of glacial acetic acid and 130 ml of ice water are added. 48.1 g (1.3 mol) of acetic anhydride are added at 5° C. and the mixture is stirred for 30 minutes. The deposited precipitate is filtered off with suction, washed intensively with 500 ml of water and dried at 80° C. Yield 83 g (0.198 mol); white solid; m.p. 309°-311° C.

Workup

  1. filtrationThe deposited precipitate is filtered off with suction
