preparation example Construction

[0027] Concrete, a kind of preparation method of polysulfonic acid structure surface wetting agent, comprises the following steps:

[0028] (1) Add dipentaerythritol and hexanoyl chloride into a three-necked flask, wherein the molar ratio of dipentaerythritol and hexanoyl chloride is 1:(3.1-3.2). After the addition is complete, stir the reaction at 30-50°C for 2-4 hours, and cool to room temperature. Neutralize with sodium hydroxide solution, wherein the concentration of the sodium hydroxide solution is 4% (mass fraction). Wash with water, extract with an organic solvent, and distill off the solvent under reduced pressure to obtain viscous liquid intermediate Ⅰ.

[0029] (2) Add the viscous liquid intermediate I obtained in step (1) into a four-necked flask, and the added amount of the viscous liquid intermediate I is 0.025 mol. Then the first solvent dimethyl sulfoxide (DMSO) was added into the four-neck flask, and the added amount was 140 mL. After all the powder is disso...

Embodiment 1

[0034] Add dipentaerythritol and hexanoyl chloride into a three-necked flask at a molar ratio of 1:3.1. After the addition is complete, stir and react at 40°C for 3h, and cool to room temperature. Neutralize with 4% (mass fraction) sodium hydroxide solution, wash with water, extract with organic solvent, and distill off the solvent under reduced pressure to obtain viscous liquid intermediate I. Take 0.025mol of the viscous liquid intermediate I and add it to the four-necked flask, then add 140mL dimethyl sulfoxide (DMSO) into the four-necked flask, and after it is completely dissolved, add 4g of powdered sodium hydroxide and stir the reaction at 30°C 0.5h, then add 0.05mol 3-chloro-2-hydroxypropyl propane sulfonate into the solution containing dimethyl sulfoxide and other solvents, raise the temperature to 85°C, and react for 6 hours, then filter the above solution with suction to obtain a solid Product Intermediate II. Add 0.02 mol of solid product intermediate II to 29.24 g...

[0036] Add dipentaerythritol and hexanoyl chloride into a three-necked flask at a molar ratio of 1:3.12. After the addition is complete, stir and react at 40°C for 3h, and cool to room temperature. Neutralize with 4% (mass fraction) sodium hydroxide solution, wash with water, extract with organic solvent, and distill off the solvent under reduced pressure to obtain viscous liquid intermediate I. Take 0.025mol of the viscous liquid intermediate I and add it to the four-necked flask, then add 140mL dimethyl sulfoxide (DMSO) into the four-necked flask, and after it is completely dissolved, add 4g of powdered sodium hydroxide and stir the reaction at 30°C 0.5h, then add 0.05mol 3-chloro-2-hydroxypropyl propane sulfonate into the solution containing dimethyl sulfoxide and other solvents, raise the temperature to 85°C, and react for 6 hours, then filter the above solution with suction to obtain a solid Product Intermediate II.

Abstract

The invention discloses a surface wetting agent with polysulfonic acid structure and a preparation method thereof. The preparation method comprises: 1) mixing dipentaerythritol and hexanoyl chloride, stirring and reacting at 30-50°C for 2-4 hours, cooling to room temperature; neutralizing , washed with water, extracted, and the solvent was distilled off under reduced pressure to obtain a viscous liquid intermediate I; 2) Add the first solvent to the viscous liquid intermediate I, and after it is completely dissolved, add powdered sodium hydroxide and stir at 25-35°C React for 0.5-1h, then add 3-chloro-2-hydroxypropylpropanesulfonate sodium into the solution, raise the temperature to 80-90°C, react for 5-7 hours, and obtain the solid product intermediate II by suction filtration; 3) the solid Add the product intermediate II into the second solvent, add hexamethylene diisocyanate under magnetic stirring, raise the temperature to 40-50°C, react for 3-5 hours, filter with suction and dry to obtain a surface wetting agent with polysulfonic acid structure. The preparation method solves the problem of poor spreading of water on the solid surface.

Description

technical field [0001] The invention relates to a surface wetting agent for chemical fiber materials, in particular to a surface wetting agent with a polysulfonic acid structure and a preparation method thereof. Background technique [0002] No matter what the situation is, the lotus can always keep itself clean. This is the so-called "lotus effect", and this phenomenon is a manifestation of moisturizing. Wetting is a phenomenon that widely exists in nature. The wetting property is one of the important properties in the theoretical study of solid surfaces. The most common wetting is that the gas on the solid surface is replaced by liquid, or solid- One liquid on the liquid interface is replaced by another liquid, and the substance that can enhance this replacement ability is a wetting agent. Wetting processes fall into three categories: wetting, wetting, and spreading. Contents of the invention [0003] In order to solve the problem of poor spreadability of water on soli...
