Natural green formaldehyde high-efficiency scavenging agent

Abstract

The invention discloses a natural green formaldehyde high-efficiency scavenging agent used for scavenging formaldehyde in air and purifying the air, belonging to the field of fine chemistry industry. The scavenging agent consists of solution of natural products containing raspberry ketone and amino or mixture of natural products containing amino, and the formula is as follows: 8%-16% (w / w) of raspberry ketone (4-hydroxy phenyl-2-butanone), 4%-12% (w / w) of lysine, 4%-8% (w / w) of glucosamine and 84%-68% (w / w) of pure water. The pH value of the solution can be adjusted by natural acid compounds such as malic acid, oxalic acid, tartaric acid and maleic acid to be within the range of 3.0-5.0. The formaldehyde scavenging agent can effectively scavenge the formaldehyde in indoor air with the scavenging rate being more than or equal to 90%.

Description

technical field [0001] The invention relates to a natural green high-efficiency formaldehyde scavenger, which belongs to the field of fine chemicals and is used for removing formaldehyde in the air and purifying the air. Background technique [0002] Formaldehyde is a colorless, irritating gas. Its harm to human health has attracted people's attention in recent years. Therefore, a natural green formaldehyde scavenger that is harmless to the human body and has no secondary pollution has been developed to remove formaldehyde in the air. , controlling formaldehyde pollution has very important practical value and social significance. [0003] The formaldehyde scavengers that have been reported at present, the first type is to contain hydrazides, amines, ureas, cyanamide chemical substances, such as patents WO200812113, WO2007149643, WO2009005974, CN1463753, CN101181677, CN1695753, CN1751760, CN101037516, and Active methylene compound ethyl acetoacetate, polyamine and other comp...

[0003] The formaldehyde scavengers that have been reported at present, the first type is to contain hydrazides, amines, ureas, cyanamide chemical substances, such as patents WO200812113, WO2007149643, WO2009005974, CN1463753, CN101181677, CN1695753, CN1751760, CN101037516, and Active methylene compound ethyl acetoacetate, polyamine and other compounds, such as CN101037516, CN101244362, the effect of the above-mentioned formaldehyde scavenger can be all, but the formaldehyde scavenger of this kind of chemical substance has certain toxicity and secondary pollution problem Another class adopts amino acid as formaldehyde scavenger, such as CN101007203, CN101138671, amino acid formaldehyde scavenger is green, pollution-free, but effect and persistence are not high;

[0004] In addition, natural formaldehyde scavenger is the extract of plants or flowers, such as CN1425725 is a formaldehyde scavenger based on tea polyphenols extracted from tea tree plants; CN101199323 extracts polyphenolic compounds; The extract of ivy; CN1635035 is the extract of honeysuckle, jasmine, hibiscus, licorice, mulberry leaves, etc. This type of formaldehyde scavenger is a natural green product, but due to the source, quality and quality control of plants and flowers, it directly affects the quality of formaldehyde.
