Abstract
The invention relates to an air purifying agent by taking long-chain alkane sulfoxide as a main material and a preparation method thereof, which belongs to the field of air purification. According to the method, calcium hypochlorite is employed for oxidizing long-chain alkane thioether to prepare the long-chain alkane sulfoxide, and then a surfactant and water are added to obtain the air purifying agent. The air purifying agent can rapidly and effectively purify air, epically purify PM2.5 and formaldehyde in air, and has certain sterilization effect.
Description
Technical field
The present invention relates to a kind of air purifying preparation, a kind of long chain alkane base sulfoxide is main air purifying preparation and preparation method, belongs to air purification field.
Background technology
Along with the raising of people's living standard, people propose the highest requirement to its living environment, more thirst for pure and fresh air as the Nature.But industrial expansion causes air quality worse and worse, air is flooded with substantial amounts of fine particle, formaldehyde, sulfur and the harmful substance such as nitrogen compound, antibacterial.People want to utilize absorption and decomposition principle to eliminate harmful gas in air, dispel various abnormal flavour, and the reagent with this function becomes air purifying preparation.Air purifying preparation has a following several types on the whole: absorbent-type air cleaning class, such as activated carbon, bamboo charcoal；Covering type taste removal product, such as solidifying de-Fragrant box, air freshener；Oxidation Decomposition type taste removal product.Absorbent-type air purifying preparation is to utilize the physical absorption of activated carbon, chemisorbed, aoxidize, be catalyzed oxidation and the performance such as reduction removes the purification product of pollutant.Covering type taste removal product is that the fragrance utilizing aromatic hydrocarbon hides the various abnormal flavour in air, to reach taste removal effect.Therefore the abnormal flavour in air is not in fact removed by a lot of air fresheners, is only to be covered by abnormal flavour with a kind of favorable odor type.Oxidized form product usually utilizes oxidant, as potassium permanganate, chlorine dioxide, hypochlorous acid or hypochlorite etc., oxidation of organic compounds or mushroom reach to purify the purpose of air.But this series products can not effectively purify the formaldehyde in air and PM2.5.
Summary of the invention
For the deficiencies in the prior art, the technical problem to be solved is to provide a kind of air purifying preparation, is purifying aerial PM2.5, formaldehyde, SO2、H2Can effectively kill the pathogenic bacteria in air while the harmful substances such as S, NO, not increase any abnormal smells from the patient.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is:
By long chain alkane base thioether CmH2m+1-S-CnH2n+1, calcium hypochlorite and water mix in the reactor with stirring, stir 3 ~ 7 hours, i.e. can get long chain alkane base sulfoxide
(referred to as SGSO) crude product.Then with saturated aqueous sodium thiosulfate cancellation to SGSO, extract with dichloromethane.SGSO, water and surfactant mix and blend are obtained emulsion, i.e. can get the air purifying preparation of the present invention.
The equation of preparing of the air purifying preparation of the present invention is:
(1)
In the air purifying preparation of the present invention, SGSO has S=O functional group.S=O functional group has polarity, negative pole is positioned on oxygen atom, and the surrounding space of oxygen atom hinders little, easily with the harmful gas in air, the interaction of such as in the gas molecules such as formaldehyde, sulfur dioxide, hydrogen sulfide, oxynitride positively charged atom generation dipole-dipole, and also positively charged with the S=O group sulphur atom of the electronegative atom in these harmful gas molecules is had an effect.Therefore, SGSO can easily fix these harmful gass, and weakens the chemical bond in these gas molecules, and then causes these harmful gas molecules of oxides, reaches to purify the purpose of air.It addition, after spray air cleaning agent, during drop landing, the long-chain SGSD of tool polar group adsorbs the fine particle in air and makes it settle therewith, reduces PM2.5 in air.
As a example by except formaldehyde, the principle that the air purifying preparation of the present invention purifies air is as follows:

Described CmH2m+1-S-CnH2n+1Middle m+n > 12.
Surfactant is dodecylbenzene sodium sulfonate, Span80 and tween.
In described technical scheme, CmH2m+1-S-CnH2n+1It is 2:1 ~ 2:1.5, C with the mol ratio of calcium hypochloritemH2m+1-S-CnH2n+1It is 1:0.05 ~ 1:0.5 with the volume ratio that the volume ratio that volume ratio is 1:1 ~ 1:5, SGSO and water is 1:1 ~ 1:20, SGSO and surfactant of water.
Beneficial effects of the present invention:
1. the present invention selects the alkane sulfoxide with sulfoxide functional group, it is possible to quickly effectively purify air, within the harmful gas concentration such as PM2.5 and formaldehyde is reduced to national standard in air；
2. the carbochain the selected alkane sulfoxide more than 12, nonpoisonous and tasteless, difficult volatilization, do not result in secondary pollution；
3. select calcium hypochlorite as oxidant, stable in properties, it is possible to effectively to prevent the formation of sulfone；And a small amount of calcium hypochlorite remained is provided that again oxidation and bactericidal effect.
