For the production of an aromatic compound by hydrolyzing and decarboxylating a corresponding aromatic cyano compound in the presence of an acidic substance, this invention provides a method for the production of the aromaic compound, characterized by carrying out the reactions of hydrolysis and decarboxylaion in multiple steps. Particularly when the aromatic cyano compound contains a halogen, this method effectively prevents the reaction vessels from being corroded by the by-produced hydrogen halogenide and enables the target compound to be produced in a high yield.
本发明提供了一种制备芳香族化合物的方法,其通过在存在酸性物质的情况下水解和脱羧相应的芳香族腈化合物来实现,其特征在于在多个步骤中进行水解和脱羧反应。特别是当芳香族腈化合物含有卤素时,该方法有效地防止了生成的氢卤酸对反应容器的腐蚀,并使目标化合物能够高产。
