Abstract (en)
[origin: CA2083715A1] 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.
Abstract (fr)
Selon un procédé de production de 1,4-bis-(4-fluorobenzoyl)-benzol par réaction de chlorure de téréphtaloyle avec du fluorobenzol en présence de chlorure ou de bromure d'aluminium, on ajoute du chlorure ou du bromure d'aluminium à un mélange de chlorure de téréphtaloyle et de fluorobenzol à des températures comprises entre 25 °C et 68 °C environ et on fait réagir le mélange à ces températures.
