Embodiment 1

[0022] 1mol C 12 h 25 -S-CH 3 , 0.5mol calcium hypochlorite and 400ml water were mixed in a stirred reactor and stirred for 3 hours. The crude p-tolylsulfoxide was then quenched with saturated aqueous sodium thiosulfate solution and extracted with dichloromethane; 200ml of SGSO, 200ml of water and 10ml of sodium dodecylbenzenesulfonate (50%) were mixed and stirred to obtain an emulsion, The air cleaner of the present invention can be obtained.

Embodiment 2

[0024] 1mol C 12 h 25 -S-C 3 h 7 , 0.75mol calcium hypochlorite and 2000ml water were mixed in a stirred reactor and stirred for 10 hours. Then quench the crude p-tolylsulfoxide with saturated aqueous sodium thiosulfate solution, extract with dichloromethane; mix and stir 200ml of SGSO, 4000ml of water and 100ml of Span80 sodium to obtain an emulsion, and the air purifier of the present invention can be obtained.

Embodiment 3

[0026] 1mol C 7 h 15 -S-C 6 h 17 , 0.65mol calcium hypochlorite and 1000ml water were mixed in a stirred reactor and stirred for 7 hours. Then quench the crude p-tolylsulfoxide with saturated aqueous sodium thiosulfate solution, and extract with dichloromethane; mix and stir 200ml of SGSO, 2000ml of water and 50ml of Tween to obtain an emulsion, and the air purifier of the present invention can be obtained.

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 [0001] The invention relates to an air purifier, in particular to an air purifier based on long-chain alkane sulfoxide and a preparation method thereof, belonging to the field of air purification. Background technique [0002] With the improvement of people's living standards, people have put forward higher and higher requirements for their living environment, and they are more eager for the fresh air like nature. However, the development of industry has led to worse and worse air quality, and the air is filled with harmful substances such as a large number of fine particles, formaldehyde, sulfur and nitrogen compounds, and bacteria. People want to use the principle of adsorption and decomposition to eliminate harmful gases in the air and remove various peculiar smells. Reagents with this function become air purifiers. Generally speaking, there are several types of air purifiers: adsorption-type air purification, such as activated carbon, bamboo charcoal; ma...
