Description

Fenoxaprop-p-ethyl etherification synthesis reaction kettle Technical Field The utility model relates to the technical field of chemical engineering, in particular to an etherification synthesis reaction kettle for fenoxaprop-p-ethyl. Background Fenoxaprop-p-ethyl is used as an efficient, low-toxicity and widely applied herbicide, and plays a key role in modern agricultural production. The etherification synthetic product has unique advantages in structure and performance, and has great significance for improving weeding effect and optimizing action mechanism. The fenoxaprop-p-ethyl is deeply explored, from chemical structure and synthesis process to practical application, the continuous innovation of weed control technology in the agricultural field is facilitated, and the requirements of the current green agricultural development on efficient and safe pesticides are met. Etherification reactions often involve liquid-liquid or liquid-solid (e.g., phenolic solid feedstock and catalyst) multiphase systems, where conventional anchor or propeller type stirring paddles can only provide axial macroscopic flow, lack sufficient shear to break up the droplet agglomerates or suspended solid particles, resulting in significant delamination of the organic phase from the aqueous phase and deposition of solids on the kettle bottom. For example, in the Williamsen ether synthesis path, when the phenolic compound reacts with the haloalkane in a two-phase system, conventional stirring takes a long time to reach a basic mixing state, and the tannin extraction rate is low due to low mass transfer efficiency, so that the byproduct yield is increased.
