Disclosed herein is a method for producing a 1-[4-(biphenyl-4-carbonyl)]phenylaminoanthraquinone colorant composition where the method comprises: reacting 4-halobenzoic acid with about 1 mole to about 4 moles of a halogenating agent per mole of said 4-halobenzoic acid to form a 4-halobenzoyl halide composition; reacting in the presence of a first catalyst composition, said 4-halobenzoyl halide composition with biphenyl, in a solvent, to form a 1-[4-(biphenyl-4-carbonyl)]halobenzene composition; and reacting in the presence of a second catalyst composition and an acid scavenger, said 1-[4-(4-phenylbenzoyl)]halobenzene composition with a 1-aminoanthraquinone, in a reaction medium comprising a dipolar aprotic solvent, to form said 1-[4-(biphenyl-4-carbonyl)]phenylaminoanthraquinone colorant composition.
本文公开了一种生产1-[4-(联苯基-4-羰基)]苯胺蒽醌染料组合物的方法,其中该方法包括:将4-卤代苯甲酸与每摩尔4-卤代苯甲酸约1摩尔至约4摩尔的卤代试剂反应,形成4-卤代苯甲酰卤组合物;在第一催化剂组合物的存在下,在溶剂中将4-卤代苯甲酰卤组合物与联苯反应,形成1-[4-(联苯基-4-羰基)]卤代苯组合物;在第二催化剂组合物和酸清除剂的存在下,在包含双极无机溶剂的反应介质中,将1-[4-(4-苯基苯甲酰基)]卤代苯组合物与1-氨基蒽醌反应,形成所述1-[4-(联苯基-4-羰基)]苯胺蒽醌染料组合物。
