preparation example Construction

[0141] The preparation process of the following examples 1 to 16 is carried out in two steps, and the reaction scheme is as follows:

[0142] A+B→Intermediate I

[0143] Intermediate I+D→E.

[0144] The structural formulas of reactants A, B, intermediate I, reactant D and product E in the examples are shown in Tables 1 and 2, respectively.

[0153] The specific reaction conditions for each example are as follows.

Embodiment 1

[0155] Add 1.35g (15mmol) of N,N-dimethylethanolamine (DMEA, compound A) and 4.35g (22.5mmol) of bromooctane (compound B) into a round bottom flask, and place it in an oil bath at 45°C React in medium for 2 hours, measure 12 mL of acetone as a solvent and add it to a round-bottomed flask, and then reflux for 12 hours; after the reaction, dry the solvent under reduced pressure at 60°C to obtain a white solid, which is washed several times with anhydrous petroleum ether, and placed in a vacuum oven Dry to obtain intermediate I, which is stored in a bottle for later use. The yield of this intermediate is 92%, and the nuclear magnetic resonance data is: 1H NMR (600MHz, D 2 O)δ3.92(tt, J=4.9,2.2Hz,2H),3.41–3.33(m,2H),3.29–3.22(m,2H),3.01(s,6H),1.66(ddd,J=15.0 ,9.4,5.6Hz,2H), 1.32–1.10(m,10H),0.75(t,J=6.8Hz,3H).

Embodiment 2

[0158] Add 1.35g (15mmol) of N,N-dimethylethanolamine (DMEA, compound A) and 9.13g (22.5mmol) of compound B (bromooctadecane) into a round bottom flask, and place in an oil bath at 35°C React in the pot for 5 hours, measure 20 mL of ethanol as a solvent and add it to the round bottom flask, and then reflux for 8 hours; after the reaction, spin the solvent under reduced pressure at 40 ° C to obtain a white solid, wash it with anhydrous ether several times, and put it in a vacuum oven Oven dry, obtain intermediate (quaternary ammonium salt alcohol, i.e. intermediate I) and preserve in the bottle for use, the productive rate of this intermediate is 92%, and nuclear magnetic resonance data is: 1 H NMR (600MHz,D 2 O)δ3.92(tt, J=4.9,2.2Hz,2H),3.41–3.33(m,2H),3.29–3.22(m,2H),3.01(s,6H),1.66(ddd,J=15.0 ,9.4,5.6Hz,2H), 1.32–1.10(m,30H),0.75(t,J=6.8Hz,3H).

[0159] Take 4.22g (10mmol) of the intermediate (quaternary ammonium salt alcohol) and 1.3g (10mmol) of N,N-diisopropylethylamine...

Abstract

The invention provides a compound, antibacterial finishing liquid, and a preparation method and application of the compound. The general formula of the compound is shown in the description. The R1 ishalogen; the R2 is halogen, hydrogen, nitryl or heteroatom substituted or unsubstituted C1-8 hydrocarbyl; X is NH, O, S and heteroatom substituted or unsubstituted C1-18 hydrocarbyl; R3 contains at least of a quaternary ammonium salt group and a phosphonium salt group. -OH and -NH2 groups on the surfaces of high molecular material surfaces of cellulose, starch, chitosan, protein, polyvinyl alcohol(PVA) and poly(hydroxyethyl acrylate) can take chemical reaction in a chemical bonding mode to be firmly combined onto the surface of the material, so that the durable antibacterial mildewproof anti-mite performance can be given to the surface of materials of fabrics; the physical performance such as the mechanical performance, the moisture and air permeability, the color and luster and the colordifference of the material per se is hardly changed.

Description

technical field [0001] The invention relates to the technical field of compounds, in particular to a compound, an antibacterial finishing solution and a preparation method and application thereof. Background technique [0002] Natural fibers (cotton, hemp, silk, wool, etc.) are one of the most used textile materials. Among them, the cotton textile industry plays an important role in the development of the national economy. In recent years, the production capacity of cotton yarn has reached 50% of the world. Cotton textiles are loved by people for their softness, breathability, moisture absorption and good wearing comfort. However, some pathogenic bacteria are easy to breed rapidly on the surface of cotton textiles, forming plaques or microbial films, causing diseases or disease infections within a certain range, which greatly affects the usability and aesthetics of cotton fabrics. Therefore, the modification around its antibacterial function becomes the key to improve the ...
