Embodiment 1

[0020] The preparation of 1-methyl-3-phenylpropylamine bis-methylene phosphoric acid: take by weighing 10 parts (current and following parts of the present invention are averaged in moles) H 3 P0 3 After adding water to dissolve, place it in a three-necked flask for reflux and stir, slowly add 12 parts of 1-methyl-3-phenylpropylamine dropwise at 50°C, slowly add 4mL HCl dropwise when the temperature rises to 75°C, and slowly add dropwise when the temperature rises to 90°C 13 parts of HCHO, finally heated up to 110°C, refluxed and stirred for 120 minutes, concentrated at 75°C to a viscous shape after the reaction stopped, after natural cooling, added 25 parts of absolute ethanol, and stood in a refrigerator at 4°C for 3-5 days. After the white solid was precipitated, it was filtered with suction and washed with absolute ethanol to obtain it.

Embodiment 2

[0022] Take 2 parts of water and 4 parts of ZrOCl 2 .8H 2 O is dissolved, slowly add a certain amount of organic phosphoric acid dropwise under stirring, the molar ratio of the two is 1.2:1, a gel solution is formed, the acidity of the system is adjusted to make the pH 0.8, and then the gel solution is transferred to a polytetrafluoroethylene After reacting in a stainless steel reaction kettle with a bottle at 140°C for 48 hours, cool it down to room temperature naturally, open the kettle, filter with suction, wash, and dry in vacuum at 55°C to obtain zirconium organophosphate.

Embodiment 3

[0024] Take 2 parts of water and 4 parts of ZrOCl 2 .8H 2 O dissolves, slowly add a certain amount of organic phosphoric acid dropwise under stirring, the molar ratio of the two is (0.8:1) ~ (1.5:1), to form a gel solution, adjust the acidity of the system to make the pH 0.5 ~ 1.5, and then add the Transfer the gel liquid into a stainless steel reaction kettle with a polytetrafluoroethylene bottle, react at 140°C for 48 hours, cool to room temperature naturally, open the kettle, filter with suction, wash, and dry in vacuum at 50-60°C to obtain organic phosphoric acid zirconium.

Abstract

The invention discloses an organic zirconium phosphate antibacterial agent. The antibacterial agent is prepared by taking as a metal ion carrier. The antibacterial agent disclosed by the invention has excellent antibacterial effect and stability and makes a great contribution to health of human beings and animals.

Description

technical field [0001] The invention relates to the field of antibacterial agents, in particular to an organophosphate zirconium antibacterial agent. Background technique [0002] With the large-scale and non-standard use of antibiotics, insecticides and fungicides, microbial resistance has increased, and the health and living environment of humans and animals have been greatly threatened. Therefore, it is urgent to develop and apply new antibacterial materials. . Existing inorganic metal ions such as Ag + 、zn 2+ It has the advantages of low toxicity, high antibacterial activity and wide antibacterial spectrum, and has become one of the most widely used antibacterial materials. However, its action time in vitro is short, and the chemical properties of inorganic metal ions are active, which are prone to change under ultraviolet light irradiation, which seriously affects its application. The layered organic zirconium phosphate of the present invention has large specific su...
