摘要:Provided is a process for recycling waste residue from the synthesis of hexachlorocyclotriphosphazene. The process comprises: reacting waste residue separated out after a synthesis reaction of hexachlorocyclotriphosphazene is finished with an ammonia source, the ammonia source being liquid ammonia, ammonia gas, ammonia water, ammonium bicarbonate, ammonium carbonate or a combination thereof; adjusting the pH value at an end point to 6-10; subjecting the obtained reaction product to solid-liquid separation so as to obtain a filtrate and a filter cake; subjecting the filter cake to post-treatment so as to obtain a recovered metal chloride catalyst; extracting the filtrate by using chlorobenzene, i.e. an extracting agent, so as to obtain an extract phase and a raffinate phase; rectifying the extract phase to obtain chlorobenzene and recovered pyridine or pyridine derivatives; and dehydrating the raffinate phase to obtain recovered ammonium chloride. By means of the process, high-degree recycling and regeneration of waste residue from the synthesis of hexachlorocyclotriphosphazene are achieved, the recovery rate of pyridine or pyridine derivatives from the waste residue can reach 95-99% or higher, the recovery rate of ammonium chloride and the metal chloride catalyst can reach 98% or higher, and no new waste residue is generated throughout the whole process.

摘要:Disclosed in the present invention is a process for recovering pyridine or pyridine derivatives from waste residue produced during the synthesis of hexachlorocyclotriphosphazene. The process comprises: stirring and mixing waste residue separated after the completion of a hexachlorocyclotriphosphazene synthesis reaction with water at a mass ratio of 1:(0.5-2.5) to obtain a mixture, adding an alkali to the mixture to perform a neutralization reaction, controlling the reaction temperature to be 0-50ºC, and adjusting the pH value of an end point to 6-10, so as to obtain a neutralization solution; centrifuging or filtering the neutralization solution to separate out a filtrate, and extracting the filtrate by using chlorobenzene, so as to obtain an extract phase and a raffinate phase; and rectifying the extract phase, so as to obtain chlorobenzene and recovered pyridine or pyridine derivatives. In the present invention, sodium chloride generated by system neutralization can be fully utilized, introduction of an external salt is not needed, salting-out and extraction are successively achieved, and a salting-out water phase is directly returned and reused after extraction, thereby lowering the output of wastewater and energy consumption regarding reuse of wastewater, greatly reducing difficulties in extraction of pyridine or pyridine derivatives, decreasing the use amount of an extraction agent, and reducing the energy consumption of a rectification separation system.
