| | 4,4'-Diaminobenzanilide Usage And Synthesis |
| Chemical Properties | off-white to grey-beige powder | | Uses | 4,4'-Diaminobenzanilide (DABA) is an organic compound that is used as an
intermediate in the synthesis of various dyes, pigments, and other
organic compounds used in the textile and printing industries. It is
also used as a intermediate in the synthesis of certain types of
pharmaceuticals and agrochemicals. | | Synthesis | 1. 30 g of 4,4'-dinitrobenzanilide obtained in step 1, 150 mL of N,N'-dimethylformamide and 0.8 g of 3 wt% palladium-carbon catalyst were added to an autoclave. The hydrogenation reaction was carried out at a hydrogen pressure of 0.8±0.1 MPa and a temperature of 100±1 °C until the reaction was complete. Upon completion of the reaction, the reaction mixture was filtered and the solvent was evaporated under vacuum to obtain the crude 4,4'-diaminobenzanilide. 2. The crude 4,4'-diaminobenzanilide obtained in step 2 was added to an autoclave with 100 g of n-butanol and 0.96 g of activated carbon, and nitrogen was passed through for three times to ensure that a positive pressure was maintained in the autoclave. Subsequently, the temperature was raised to 135±1 °C and stirred for 20 min. The filtrate was filtered under nitrogen protection, the filtrate was cooled to 25±1 °C, filtered again and dried. Finally, 22.8 g of electronic grade 4,4'-diaminobenzanilide in the form of white crystalline powder was obtained in 96.1% yield and 99.7% purity (HPLC). | | References | [1] Patent: CN108329224, 2018, A.
