Description

technical field [0001] The invention relates to the technical field of formaldehyde removers, in particular to a preparation method of an environment-friendly formaldehyde remover. Background technique [0002] Formaldehyde, chemical formula HCHO or CH 2 O, molecular weight 30.03, also known as formaldehyde. Colorless, irritating to human eyes and nose. The relative density of gas is 1.067 (air=1), and the density of liquid is 0.815g / cm³ (-20℃). Melting point -92°C, boiling point -19.5°C. Soluble in water and ethanol. The concentration of the aqueous solution can reach up to 55%, usually 40%. It is called formalin, commonly known as formalin, which is a colorless liquid with a pungent odor. [0003] On October 27, 2017, in the list of carcinogens published by the World Health Organization's International Agency for Research on Cancer, formaldehyde was included in the list of a class of carcinogens. [0004] The removal of formaldehyde has always been an object of resea...
