Versuchsvorschrift

To a suspension of 464 gm (1 mole) of tetrabromophthalic anhydride in 1.2 liters of xylene was added 61 gm (1 mole) of ethanolamine. The solution was heated and refluxed with a Dean-Stark water separator until the theoretical amount of water separated. The mixture was cooled, diluted with hexane, and filtered. The resulting 413 gm of an off-white solid was washed with hexane and dried at 100° C. This material is used as is for subsequent reactions without further purification.
