Abstract

The invention discloses a preparation method of a stable compound halogen organic disinfectant. The stable compound organic disinfectant provided by the invention comprises main effective components of 1,3-dibromo-5,5-dimethylhydantoin (or 1,3-dichloro-5,5-dimethylhydantoin or 1-bromo-3-chloro-5,5-dimethylhydantoin) and trichloroisocyanuric acid (or sodium dichloroisocyanurate); necessary auxiliary additives (anhydrous sodium sulfate, sodium chloride or sodium bromide, sodium carbonate or sodium bicarbonate and sodium alkyl benzene sulfonate) are added; and dosage forms include powder, granules and tablets.

Description

technical field [0001] The invention relates to the field of organic chemistry, in particular to a preparation method of a stable compound halogen organic disinfectant. Background technique [0002] The halogenated organic compounds dibromohydantoin and trichloroisocyanuric acid are internationally recognized and recommended broad-spectrum disinfectants, sterilizers, algicides and deodorants for external use. Widely used in drinking water disinfection, hotel, restaurant, hospital disinfection and sterilization. [0003] Dibromohydantoin can continuously release new ecological Br ions by dissolving in water, and generate hypobromous acid with strong oxidative properties. It can oxidize and decompose the biological enzymes in microorganisms to lose efficacy, and has a strong bactericidal effect. It is widely used in Disinfection treatment of industrial water treatment systems, indoor and outdoor swimming (bath) pools, sanitation systems and aquaculture water environments. It ...
