Description

technical field [0001] The invention relates to the technical field of fluidized bed reactors, in particular to a chlorination fluidized bed reactor for chlorothalonil production. Background technique [0002] Chlorothalonil, also known as 2,4,5,6-tetrachloro-1,3-phthalonitrile, has a molecular formula of C8Cl4N2 and is a broad-spectrum protective fungicide. Chlorothalonil can interact with glyceraldehyde triphosphate dehydrogenase in fungal cells, combine with the cysteine-containing protein in the enzyme, thereby destroying the enzyme activity, destroying the metabolism of fungal cells and losing their vitality. Chlorothalonil has no systemic conduction effect, but after sprayed on the plant body, it can have good adhesion on the body surface and is not easily washed off by rain, so the drug effect period is longer, and chlorothalonil is usually used in the production of chlorothalonil. Fluidized bed reactor, fluidized bed reactor refers to the equipment in which gas unde...
