3,5-Dicarboxyaniline Use and Manufacturing
In a 3 L four-necked flask equipped with a mechanical stirrer, a thermometer was charged 211.1 g (1.0 mol, 1.0 eq) of 5-nitroIsophthalic acid, 160.0 g (4.0 mol, 4.0 eq) of sodium hydroxide in 2 L of water, and the mixture was stirred for 1 hour to clarify the system. Then add 10g of Raney nickel, slowly raise the temperature between 30 ~ 35 , and then drop into the 80percent hydrazine hydrate 125.0g (2.0mol, 2.0eq), 30 minutes drop finished, continue stirring for 30 minutes to end the reaction. The pH of the filtrate was adjusted to 3.5 to 4.0 with acetic acid, and a large amount of white solid was precipitated by filtration and dried to obtain 172.0 g of 5-aminoisophthalic acid in a yield of 95percent and purity of 99.7percent ).
