Zusammenfassung: | The invention provides a continuous production system for azo reactive dyes by applying hyper gravity, the continuous production system combines a spiral coil reactor and a hyper gravity technology, and treats diazotization reaction and coupling reaction differently, the diazotization reaction is carried out in the spiral coil reactor, and the conversion rate and product quality can be greatly improved by using a hyper gravity reactor for coupling reaction. However, the spiral coil reactor can accurately control the temperature and avoid decomposition of diazonium salt. In this way, due to accurate temperature control, the decomposition of the diazonium salt is extremely small and may not affect the subsequent coupling reaction, thus ensuring that the concentration of the diazonium salt ismaintained in a higher range during continuous production, thus ensuring that the performance of the azo reactive dyes in the same batch is close to or the same, and meeting the actual needs of industry. Furthermore, a distu |
