- Product Description
Formaldehyde,also known as formaldehyde,is an organic compound with the chemical formula CH2O,a relative molecular weight of 30.03,a melting point of-92¡æ,a boiling point of-19.5¡æ,and a relative density of 0.815g/cm3.A 35-40%formaldehyde aqueous solution is commonly known as formalin solution.
Formaldehyde,a colorless gas,is not easily detectable at low concentrations and can be easily masked by other odors such as air fresheners.At higher concentrations,it has a strong irritant and suffocating odor that can irritate the eyes,nose,and other senses.Formaldehyde is a toxic gas that currently poses a serious threat to human health,and is commonly found in furniture and decoration materials that do not meet quality standards.Long term exposure to a high concentration of formaldehyde may cause dizziness,headache,tears,nausea and vomiting,coughing,chest tightness,leukemia,and other symptoms in patients.In severe cases,it can lead to death.Therefore,it is important to stay away from formaldehyde in daily life,regularly ventilate newly renovated houses,and monitor formaldehyde levels.Formaldehyde has reducibility,especially in alkaline solutions,with stronger reducing ability and the ability to burn.Its vapor forms an explosive mixture with air,with an explosive limit of 7%-73%(volume percentage)and an ignition point of about 300¡æ.(Some say 430¡æ).
Formaldehyde has a wide range of applications in industries such as petrochemicals,pharmaceuticals,textiles,biochemistry,energy,and transportation.It can be used as a disinfectant and preservative,as well as in the preparation of various products such as phenolic resins,urea formaldehyde resins,melamine resins,urotropin,and pentaerythritol.Formaldehyde has a strong irritant and tear jerking effect on mucous membranes,can cause protein coagulation,and can easily make the skin hard or even cause local tissue necrosis when touched.
