Abstract

The invention discloses a deodorant containing a macrocyclic compound, and a preparation method of the deodorant, and belongs to the technical field of light chemical engineering. The deodorant disclosed by the invention is prepared from the following components in parts by weight: 0.1 to 10 parts of a macrocyclic compound, 0.1 to 50 parts of a surfactant and 30 to 100 parts of a solvent. According to the deodorant, the removal rate of ammonia gas reaches 80% or above, the removal rate of hydrogen sulfide reaches 80% or above, the removal rate of isoamyl alcohol reaches 75%, the removal rate of acetaldehyde reaches 83%, and the removal rate of trimethylamine reaches 85% or above.

Description

technical field [0001] The invention relates to a deodorant containing a macrocyclic compound and a preparation method thereof, belonging to the technical field of light chemical industry. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the cleanliness of the living environment. Many deodorants used in the household field use essence to cover the odor molecules to achieve the purpose of deodorization, but this method cannot fundamentally solve the odor; or use activated carbon and other physical adsorption technologies to deodorize, but this technology After the adsorption is saturated, the odor will be released, which is not conducive to completely solving the problem. Contents of the invention [0003] In order to solve at least one of the above-mentioned problems, the present invention uses a macrocyclic compound with a three-dimensional cavity structure to combine odor molecules to treat the odor g...
