Embodiment 1
[0022] Vinyl Monomer Absorbent Composition 1
[0023] Dissolve 64 kg of isopropanol in 168 kg of water, and carefully add 80 kg of potassium hydroxide. Stir to combine all three evenly.
Embodiment 2
[0025] Vinyl Monomer Absorbent Composition 2
[0026] Dissolve 52 kg of methanol in 168 kg of water, and carefully add 20 kg of calcium hydroxide. Stir to combine all three evenly.
Embodiment 3
[0028] The air polluted by ethyl acrylate is passed into the absorption tower with composition 1 at a rate of 50 liters / minute, and the temperature of the tower is kept at 56° C. The exhaust gas from the absorption tower does not have any ethyl acrylate odor. Gas chromatography detects that ethyl acrylate is not detected above 50 ppm.

The invention discloses an alcohol composition which can remove vinyl monomer. The alcohol composition contains at least one of primary and secondary alcohols and also contains a solvent and at least one lewis alkalis; the invention also discloses a method by using the composition to remove vinyl monomer; the method is that: under a certain temperature T, the mixture of gas phase and liquid phase containing vinyl monomer which touches the composition through a reaction device to realize the purpose of absorbing vinyl monomer, thus the vinyl monomer in the mixture can be effectively removed finally. The invention has the advantages of low energy consumption, no discharging of greenhouse gases and the product being able to regenerate the original vinyl monomer.
Description
technical field [0001] The invention relates to an alcohol composition capable of eliminating vinyl monomers and a method for using the composition. Background technique [0002] Vinyl monomers are widely used in industry, such as: polymers, coatings, leather, paper, textiles, adhesives, water treatment, daily chemicals, construction, functional polymer materials and other production fields. However, in this production process, vinyl monomers are usually used as raw materials, and most of the vinyl monomers have an unbearable odor. During the production process, there will inevitably be pollution such as steam volatilization, tail gas emissions, and material leakage. Situation happens. Therefore, in the industry, liquid nitrogen cryogenics and mixed combustion with fuel oil are usually used to eliminate them. However, there are disadvantages such as huge waste of energy, secondary pollution, and high processing costs in such processing. This makes its social and economic ...
