Abstract

The invention relates to the technical field of sterilization and disinfection materials, in particular to a compound containing an α-substituted phenyl structure, a preparation method thereof and a disinfectant. The compound containing α-substituted phenyl structure provided by the present invention produces bactericidal effect by promoting protein coagulation and denaturation of pathogenic microorganisms, especially for pathogenic bacteria such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis var. Good killing effect, no corrosion to metal, no irritating smell, good water solubility, green and environmental protection, can be widely used in various industries as an active ingredient of disinfectant.

Description

technical field [0001] The invention relates to the technical field of sterilization and disinfection materials, in particular to a compound containing an α-substituted phenyl structure, a preparation method thereof and a disinfectant. Background technique [0002] Disinfectants are widely used in the fields of medical treatment, animal husbandry, forestry and aquaculture. As people's requirements for sanitation are increasing, the demand for disinfectants is also increasing. At present, the disinfectants sold and used in the market can be roughly divided into nine categories: chlorine-containing disinfectants, peroxide disinfectants, ethylene oxide disinfectants, aldehyde disinfectants and phenolic disinfectants, etc. However, there are generally disadvantages such as strong taste and poor sterilization effect. Contents of the invention [0003] The object of the present invention is to provide a compound containing α-substituted phenyl structure and its preparation meth...
