Abstract
The invention provides a green production technology for bromothalonil. The technology has the advantages that operation is easy, the production process is green and free of pollutant discharge, used solvent can be recycled and reused, the product yield is high, the production cost is effectively reduced, energy is saved, consumption is reduced, and the obtained bromothalonil is high in content, good in crystal form and low in color number and can be combined with multiple bactericides to form a sterilization composition, and effectively inhibit and eradicate growth of bacteria, fungi and algae.
Description
technical field [0001] The invention relates to a green production process of bromothalonil. Background technique [0002] Bromothalonil (bromothalonil), chemical name: 1,2-dibromo-2,4-dicyanobutane, is a compound with low toxicity and broad-spectrum bactericidal, anti-mildew and algicidal properties, which can inhibit and Eliminates bacterial, fungal and algal growth. It is a broad-spectrum, high-efficiency, and low-toxic fungicide, which can inhibit and eradicate the growth of fungi, bacteria, and algae. It has a good control effect on crop diseases and has special effects on anthracnose. Widely applicable to fruit trees, grapes, vegetables, cotton, peanuts, watermelon, tobacco, tea trees, flowers and other crops, to prevent and control anthracnose, scab, scab, powdery mildew, rust, blight, damping-off, rhizome Rot, canker, bacterial wilt, angular spot and other fungal and bacterial diseases. The application method is flexible, and foliar spray, seed treatment and soil ...
