Abstract

The present disclosure provides a compound and methods of preparing the compound. The compound has anti-microbial and anti-mite properties and can be bonded to materials such as fiber and synthetic polymer. The compound may also be used in a finishing agent for textiles, fibers, or yarns to protect these materials against microorganisms and mites. Additionally, when these materials are treated with a relatively low dosage of the compound, long-lasting and effective anti-mold and anti-mite effects may be achieved at a relatively low cost.

First claim

We claim:

1. A compound, having a structure represented by a general formula (I):

wherein R 1 is halogen;
R 2 is H, halogen, —NO 2 or C 1-8 hydrocarbyl that is unsubstituted or substituted with one or more heteroatoms;
X is O or S; and
R 3 is

wherein:
a=0-17;
b=0-17; and
Y is halogen.

2. A method of preparing the compound (I) of claim 1 , comprising:
reacting HX—R 3 with a compound having a structure represented by the general formula (III) to obtain the compound (I).

3. The method of claim 2 , wherein the reacting HX—R 3 with a compound having a structure represented by the general formula (III) to obtain the compound (I) includes:
reacting HX—R 3 with the compound having the structure represented by the general formula (III) under the presence of a Lewis base, wherein the Lewis base is preferably selected from the group consisting of alkali metal, inorganic base of alkaline earth metal, and an organic tertiary amine.

4. The method of claim 3 , wherein
the inorganic base is selected from the group consisting of sodium hydroxide, potassium hydroxide, magnesium hydroxide, calcium hydroxide, potassium carbonate, potassium hydrogencarbonate, sodium carbonate, sodium hydrogencarbonate, and combinations thereof; and
the organic tertiary amine is selected from the group consisting of N, N-diisopropyl-ethylamine, trimethylamine, triethylamine, N, N-dimethyl-n-octylamine, N, N-dimethylaniline, N, N-dimethyl-dodecylamine, N, N-dimethyl-dodecylamine, N, N-dimethyl-hexadecylamine, N, N-dimethyl-octadecylamine, N, N-dimethyl-decylamine, dimethylaminoethyl methacrylate, diethylaminoethyl methacrylate, and combinations thereof.

5. An anti-microbial or anti-mite product, comprising the compound of claim 1 .

6. The product of claim 5 , wherein the content of the compound is 0.05%-10% of the product by weight.

7. The product of claim 5 , wherein the content of the compound is 0.1-5% of the product by weight.

8. The product of claim 5 , wherein the pH of the product is between 8-11.

9. The product of claim 5 , wherein the product is used to kill microorganisms or mites, the microorganisms including at least one of Escherichia Coli, Staphylococcus Aureus, Candida Albicans , or Aspergillus Niger.

10. The product of claim 5 , wherein the product is a finishing agent for treating textiles, fibers, or yarns.
