PROCESS FOR THE PREPARATION OF 1,4-BIS(4-FLUOROBENZOYL)-BENZENE

摘要

Process for producing 1,4-bis-(4-fluorbenzoyl)-benzol by reacting terephthaloyl chloride with fluorbenzol in the presence of aluminium chloride or aluminium bromide characterized in that aluminium chloride or aluminium bromide is added in metered quantities to a mixture of terephthaloyl chloride and fluorbenzol at temperalures of approximately 25.degree.C to approximately 68.degree.C and the mixture is allowed to react at said temperatures.
