Abstract

The invention belongs to the technical field of disinfectants, and discloses a furyl double-long-chain quaternary ammonium salt compound as well as a preparation method and application thereof. The preparation method of the furyl double-long-chain quaternary ammonium salt compound comprises the following steps: carrying out a reaction I on a mixture containing a compound i and a compound ii in the presence of an alkaline substance or an acidic substance to obtain an imine compound P; mixing the imine compound P with a reducing reagent for reaction II to obtain a double-long-chain secondary amine intermediate product K; or the compound III reacts with the compound III in the presence of a halogenating reagent to obtain the chlorinated compound O; the chlorinated compound O and a compound i are mixed to react IV, and a double-long-chain secondary amine intermediate product K can be obtained; and reacting the double-long-chain secondary amine intermediate product K with a chloroethane reagent V to obtain the furyl double-long-chain quaternary ammonium salt compound. The furyl double-long-chain quaternary ammonium salt compound disclosed by the invention has a rapid killing effect on bacterial propagules as an organic disinfectant.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, and in particular relates to a furan-based double long-chain quaternary ammonium salt compound, a preparation method and its application as a disinfectant. Background technique [0002] In order to strengthen personal hygiene protection and reduce new coronavirus infection, the development of efficient, safe and green disinfectant products is a common concern of the society. [0003] Compared with traditional chlorine-containing disinfectants and peroxide disinfectants, quaternary ammonium salt type disinfectants have the advantages of low toxicity, less odor, convenient use, and easy storage. They are very suitable for use as household disinfection products. [0004] Through the above analysis, the existing problems and defects in the prior art are: [0005] (1) Traditional disinfectants are highly irritating, and long-term use is detrimental to human health; [0006] (2) Traditional dis...
