| titleOfInvention | Dicyanobenzene production method and production apparatus |
| abstract | In producing a dicyanobenzene by ammoxidation of xylene, an object is to prevent the deterioration and loss of the dicyanobenzene and to produce the dicyanobenzene industrially and economically advantageously. In the method for producing dicyanobenzene of the present invention, an ammoxidation reaction gas of xylene is brought into contact with an organic solvent to obtain a dicyanobenzene absorbing solution, and the dicyanobenzene absorbing solution is brought into contact with a basic aqueous solution containing a salt such as ammonium carbonate. The water-soluble salt produced by the neutralization reaction between the carboxylic acid in the dicyanobenzene absorbing solution and the base in the basic aqueous solution is extracted into the aqueous phase, and the mixture of the dicyanobenzene absorbing solution and the basic aqueous solution is extracted into the organic phase. And the aqueous phase, decompose the salt of the ammonium carbonate tower contained in the organic phase, separate the salt from the organic phase, distill the organic phase, and separate the low boiling point compounds contained in the organic phase from the organic phase Thus, dicyanobenzene is obtained. |
