Description

Technical Field

[0001] This utility model relates to the field of quinclorac processing technology, and in particular to a quinclorac processing feeding device. Background Technology

[0002] Quincloprid, a highly effective and broad-spectrum pesticide, has been widely used in agricultural production in recent years. Its unique chemical structure endows it with excellent insecticidal and fungicidal activity, demonstrating significant control effects against various crop diseases and pests. With the acceleration of agricultural modernization and the increasing resistance of pests and diseases, the demand for quincloprid is constantly increasing, while also placing higher demands on its purity, stability, and environmental friendliness. Therefore, in-depth research into the synthesis process of quincloprid to improve product quality and yield is of great significance for ensuring agricultural production safety and promoting sustainable agricultural development.

[0003] In the preparation of quinclorac, the optimization and innovation of key steps are crucial for improving production efficiency and reducing costs. Traditional preparation methods often involve multiple chemical reactions, including complex processes such as acylation, esterification, and rearrangement. The control of reaction conditions, raw material selection, and catalyst use at each step directly affect the quality and yield of the final product. In particular, the purity of raw materials and the control of byproducts during the reaction process are significant challenges in the preparation of high-quality quinclorac. Therefore, developing efficient and environmentally friendly preparation processes to achieve large-scale and green production of quinclorac is currently one of the research hotspots in the field of pesticide synthesis.

[0004] In the preparation of quinclorac, precise control of the reaction requires the addition of specific amounts of acylating agents, depolymerizing agents, 1,3-cyclohexanedione, and acid-binding agents to the reactor in batches. To facilitate feeding, the preparation process tends to use solid raw materials, which must be pulverized before addition. Simultaneously, to ensure the smooth progress of the reaction and minimize environmental impact, the reactor must be kept as closed as possible during raw material addition to prevent waste gas leakage or heat loss from interfering with external processes and potentially disrupting the preparation process. However, current feeding methods primarily use feeding pipes, which cannot achieve completely closed feeding. Therefore, a fully enclosed feeding device is urgently needed to meet the feeding requirements in the preparation of quinclorac. Utility Model Content
