Paragraph 7; 11, (2017/07/07)
The invention provides a triazine quaternary ammonium salt halamine antibacterial agent. The triazine quaternary ammonium salt halamine antibacterial agent is a compound with a structure as shown in a formula (I) in the specification. The preparation method comprises the following steps: (1) dropwise adding an organic solution of 2,2,6,6-tetramethyl-4-piperidylamine into an aqueous or organic solution of cyanuric chloride or cyanuric fluoride, and carrying out a reaction for 1 to 4 h; (2) pouring an aqueous solution of chlorinated N-(2-ethylamino)-pyridine into the reaction solution, carrying out a reaction for 2 to 6 h, dropwise adding an acid-binding agent in the whole process of the reaction, and allowing the pH value of the reaction solution to be 5.0 to 8.0; (3) after the reaction is completed, carrying out filtering, purifying and drying so as to obtain a triazine quaternary ammonium salt halamine antibacterial precursor; and (4) placing the triazine quaternary ammonium salt halamine antibacterial precursor into a halogenated solution, carrying out standing at room temperature for 0.5 to 1.5 h, and after completion of standing, carrying out filtering and drying so as to obtain a quaternary ammonium salt halamine antibacterial agent product. The triazine quaternary ammonium salt halamine antibacterial agent provided by the invention is a salt-free reaction-type halamine antibacterial agent with excellent antibacterial properties and good precursor water-solubility.
