Post-treatment of nitration reaction liquid is an important link in chemical production, and is of great significance for improving product quality, reducing costs and protecting the environment. However, traditional post-treatment methods have problems such as low efficiency and high cost. In order to solve these problems, we proposed a continuous extraction technology for post-treatment of nitration reaction liquid.
The continuous extraction technology for post-treatment of nitration reaction liquid refers to the continuousization of multiple post-treatment processes to achieve continuous production. Efficient and low-cost post-treatment can be achieved by optimizing process flow, improving equipment efficiency, and reducing energy consumption. At the same time, continuous technology can also improve product quality, reduce waste emissions, and achieve sustainable development.
Nitration reaction post-treatment continuous extraction and separation process
The nitration reaction is realized by using a microchannel reactor to realize the continuous reaction stage. The product after the reaction needs to be separated, washed with water, washed with alkali, washed with water, etc. The centrifugal extractor can realize the continuous separation of the reaction liquid (oil phase, acid phase) produced from the microchannel reactor. The separated oil phase enters the next stage of centrifugal extractor for continuous water washing. After water washing and separation, the oil phase enters the next stage of centrifugal extractor for continuous alkali washing. Finally, it is washed with water once more to complete the separation, washing, alkali washing, and washing process.
The use of centrifugal extractor can achieve continuous extraction, which has the advantages of thorough separation, low power consumption, and fully automated operation.
Advantages of continuous post-treatment of nitration reaction

- Reduce costs: By optimizing equipment selection and process flow, production costs and energy consumption are reduced.
- Improve product quality: Continuous extraction technology can reduce the impact of manual operation on product quality and improve product quality stability.
- Protect the environment: Continuous extraction technology can reduce waste emissions and energy consumption, reducing the impact on the environment.
The continuous extraction technology of post-treatment of nitration reaction liquid is an important development direction in chemical production. By adopting advanced extraction equipment and technical means to achieve continuous production, we can improve efficiency, reduce costs, improve product quality and protect the environment. We believe that with the continuous advancement and innovation of technology, the continuous extraction technology of post-treatment of nitration reaction liquid will be more widely used and promoted.
