In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.
The utility model provides an acid halide post-treatment device, which is shown in figure 1 and comprises a reactor 1, a water washing device 2, a distillation tower 3, a neutralization reactor 6, a filter and a crystallization device 9, wherein the reactor 1 is used for containing a reaction mixture containing acid halide, the reaction mixture is sequentially treated by the water washing device 2, the distillation tower 3, the neutralization reactor 6, the filter and the crystallization device 9, the water washing device 2 is used for carrying out water washing treatment on the reaction mixture, the distillation tower 3 is used for carrying out distillation separation on the acid halide after water washing and moisture, the neutralization reactor 6 is used for carrying out reaction neutralization on the distilled acid halide and alkaline substances, the filter is used for further filtering impurities in a reaction product, and the crystallization device 9 is used for promoting crystallization of the acid halide in the crystallizer.
The filter is an activated carbon filter 7, and other types of filters may be used in other embodiments.
The reaction mixture obtained after the reaction in the reactor 1 is passed to a water washing apparatus 2 for water washing for the purpose of removing acidic residues in the reaction mixture. When the acid halide is contacted with water, the acid groups in the acidic residue react with hydroxide ions (OH-) in the water to form a water soluble salt or acidic species. These water-soluble substances will dissolve from the mixture into the aqueous phase, thereby effecting the removal of the acidic residue, and the eluted mixture of the acid halide and the residual moisture is distilled off by the distillation column 3. Since the acid halide and water have different boiling points, the acid halide and water can be separated by heating the mixture and fractionating it in the distillation column 3. The purified acid halide is obtained after distillation, and the distilled acid halide is further subjected to neutralization reaction with an alkaline substance in a neutralization reactor 6, wherein the neutralization reaction aims at removing excessive acidic components in a distillation product, and in the neutralization reaction, the alkaline substance (such as sodium hydroxide or potassium hydroxide) reacts with acid groups in the acid halide to generate corresponding salt and water. Thus, the excess acidic component is neutralized to obtain a purer acid halide, and after the neutralization reaction, the product is further purified by the activated carbon filter 7. Activated carbon is a highly adsorptive material that adsorbs organics, including impurities of some acid halides. Residual organic impurities can be further removed by passing the product through an activated carbon filter 7, increasing the purity of the product- > finally, the product is purified by a crystallization device 9. By controlling the temperature and solvent conditions, the acid halide can be promoted to crystallize in a crystallizer, so that a purified product is separated, and crystallization is an effective purification method, and the purity and quality of the product can be further improved.
The acid halide post-treatment device provided by the utility model effectively removes acid residues and organic impurities through multi-step treatment processes including water washing, distillation, neutralization reaction, filtration, crystallization purification and the like, and greatly improves the purity of the product. The system is reasonable in design, and the safety and stability of operation are ensured through measures such as distillation, neutralization and filtration. The operation flow is simple and easy, and the method is suitable for acid halide treatment with different scales and types, and is economical and practical. Therefore, the device provides an efficient, safe and economical solution for the acid halide post-treatment process, and ensures the high purity and high-quality chemical quality of the product.
In some embodiments, in order to improve distillation efficiency and stability of materials, the embodiment further includes a vacuum pump 4, where the vacuum pump 4 is used to pump out gas in the distillation tower 3, and is used to provide vacuum conditions during distillation, reduce reaction temperature, and avoid decomposition of products. When the acid halide is distilled and separated from the water, the water is first converted into steam and then distilled, and the acid halide distillation product is introduced into the neutralization reactor 6.
In some embodiments, in order to uniformly collect and post-treat the wastewater, the embodiment further comprises a wastewater storage tank 5, and the wastewater generated by the reactor 1, the distillation tower 3, the filter and the neutralization reactor 6 is discharged to the wastewater storage tank 5 for storage.
