Problems solved by technology

At present, foreign cationic active disinfectants have been developed to the fifth generation, that is, didodecyl diquaternary ammonium salt (Gemini). After research, it is found that this type of compound has better performance than the corresponding monoquaternary ammonium salt compound. It has a good surface activity and high bactericidal activity, and has a good response in the animal husbandry industry, but it is also found that its bactericidal rate is slow, its ability to kill viruses, spores and mixed viruses is poor, and its anti-interference ability to organic matter is poor. , the cost is also higher

Abstract

A single-double strand mixed quaternary ammonium salt composite triclocarban disinfectant and a preparation method thereof are disclosed. The mass ratio of a mixed quaternary ammonium salt to triclocarban in raw materials is 2:1 to 4:1. The preparation method comprises the following steps: (1) putting the mixed quaternary ammonium salt in a reaction kettle for stirring evenly; (2) adding triclocarban to the reaction kettle, and stirring for 4-6 h at the temperature of 40-50 DEG C: and (3) adding water to dilute the solution, and mixing evenly to obtain the finished product.

Description

technical field [0001] The invention belongs to the field of veterinary drug disinfectants, in particular to a single- and double-chain mixed quaternary ammonium salt compound triclocarban disinfectant and a preparation method thereof. Background technique [0002] Quaternary ammonium salt is a kind of cationic surfactant. Chemically, they have four carbon atoms covalently bonded to a nitrogen atom. Quaternary ammonium disinfectants are widely used for deodorizing, cleaning and surface disinfection. It has antibacterial effect at low concentrations, and can kill most types of bacterial propagules and some viruses at high concentrations. At present, foreign cationic active disinfectants have been developed to the fifth generation, that is, didodecyl diquaternary ammonium salt (Gemini). After research, it is found that this type of compound has better performance than the corresponding monoquaternary ammonium salt compound. It has a good surface activity and high bactericid...
