Abstract

The invention provides a dication quaternary ammonium complex iodine disinfectant. The dication quaternary ammonium complex iodine disinfectant comprises the following ingredients in parts by weight: 10-200 parts of organic amine, 5-100 parts of trimethylamine hydrochloride, 5-150 parts of epoxy chloropropane, 1-50 parts of catalyst, 1-10 parts of buffering agent, 10-100 parts of leveling agent, 10-100 parts of iodine and 10-200 parts of de-ionized water. The preparation process of the disinfectant provided by the invention is simple and convenient; and the prepared disinfectant has the advantages of high efficiency, low toxicity, broad spectrum and less residue. The disinfectant provided by the invention can be widely applied to water disinfection of aquaculture and disease prevention of aquatic animals.

Description

technical field [0001] The invention relates to a novel dication quaternary ammonium salt complexed iodine disinfectant, its preparation method and application. Background technique [0002] Since Domagk discovered the bactericidal effect of cationic surfactants in 1935, the research work on quaternary ammonium salt disinfectants has made significant progress, and has been increasingly widely used in fields such as medical and health care, oil field exploitation, civil and aquaculture disinfection. So far, four generations of quaternary ammonium salt disinfectants have been developed internationally. The first-generation product is alkyl dimethyl benzyl ammonium chloride, in which the product with an alkyl chain length of 12 to 16 carbons has the best bactericidal effect, and the second-generation disinfectant is a derivative of the first-generation product, which is produced through The third generation product is dialkyl dimethyl ammonium chloride. Compared with the previ...
