Mass production method of phenylenediamine from high purity dinitrobenzene |
| abstract |
The present invention relates to a method for producing phenylenediamine using high-purity dinitrobenzene, and it is possible to produce dinitrobenzene in which aniline is not produced as a by-product, thereby producing meta-phenylenediamine having high yield. By using this process, meta-phenylenediamine is produced using inexpensive raw materials without additional purification process, and thus the manufacturing cost can be significantly reduced compared to the existing one, and it is possible to induce a stable reaction even in the synthesis process. -Phenylenediamine can be produced more safely and easily. |
