Formaldehyde is a colorless poisonous gas synthesized by the oxidation of methanol and used as an antiseptic, disinfectant, histologic fixative, and general-purpose chemical reagent for laboratory applications. Formaldehyde is readily soluble in water and is commonly distributed as a 37% solution in water; formalin, a 10% solution of formaldehyde in water, is used as a disinfectant and to preserve biological specimens. Environmentally, formaldehyde may be found in the atmosphere, smoke from fires, automobile exhaust and cigarette smoke. Small amounts are produced during normal metabolic processes in most organisms, including humans.
At room temperature, formaldehyde is a colorless, flammable gas that has a distinct, pungent smell. It is also known as methanal, methylene oxide, oxymethyline, methylaldehyde, and oxomethane. Formaldehyde is naturally produced in small amounts in our bodies. It is used in the production of fertilizer, paper, plywood, and urea-formaldehyde resins. It is also used as a preservative in some foods and in many products used around the house, such as antiseptics, medicines, and cosmetics.
[application 1] It can be used as disinfectant for human, antiseptic and fumigant for animals
[application 2] Used as organic chemical raw materials, medicine, synthetic fiber, synthetic resin, plastic preservative, reducing agent, etc
[application 3] It can be used as chromatographic analysis, disinfectant, preparation of phenolic resin and bioleaching
[application 4] It is mainly used to prepare phenolic resin, urea formaldehyde resin, melamine resin and polyoxymethylene resin. It is also used to prepare MDI, pentaerythritol, urotropine and butanediol
[application 5] The water solution is antiseptic and fumigant. It has strong bactericidal effect and is effective for spores and viruses. 2% formalin can be used for disinfection of instruments and gloves (soaking for 1-2 hours). Formaldehyde vapor can be produced by indoor use of 1-2 ml / m3 formalin and a small amount of potassium permanganate crystal.
[Purpose 6] It is used for tanning fur, fixing casein finishing agent and disinfecting raw leather warehouse. Should be stored in a ventilated, dry warehouse, containers should be sealed, not too cold or overheating, to 25 ℃ is appropriate, to prevent sunlight exposure, not for a long time. Wear masks, glasses, gloves and other protective equipment when using.
[Purpose 7] As a green feed additive.
[Purpose 8] Formaldehyde is an important raw material of pesticides. It can be used to prepare fungicides such as nicotinic acid, Triadimefon, bromonitrol, insecticides such as phorate, terbuthion, permethrin, bifenthrin, pyridaben, phoxim, herbicides such as herbicides such as chlorpyrifos, metolachlor, acetochlor, butachlor, isopropylamine, glyphosate, tribenuron methyl, imidazolium ethylnicotinic acid, plant growth regulators such as mepiquat, Paclobutrazol, Uniconazole, etc Products. [other uses] Analysis and determination of ammonium salts and amino acids, microscopic analysis of various preparations of fixatives, disinfectants, fungicides, reducing agents. Used for ICP-AES, AAS, AFS, ICP-MS, ion chromatography, etc. Standard solution for titration analysis. Calibration of instruments and devices; evaluation methods; work standards; quality assurance / quality control.
[Purpose 9] Formaldehyde is one of the most important derivatives of methanol, accounting for 40% of methanol consumption. The consumption composition is: urea formaldehyde resin 46%, phenolic resin 9%, pentaerythritol 8%, melamine resin 6%, polyformaldehyde 6%, 1,4-butanediol 5%, trihydroxypropane 3%, urotropine 3%, MDI 2%, and other 12%. In China, formaldehyde is mainly used in the production of urea formaldehyde resin, phenolic resin, pentaerythritol and Urotropine, etc. it is also used in light industry, textile, medicine, electromechanical, chemical industry, building materials, oil field development, wood processing and other departments, of which chemical industry accounts for about half. In addition to the above main uses, formaldehyde itself is widely used as fine chemicals and as raw materials for fine chemicals. Formaldehyde is a kind of antiseptic, which has strong killing effect on Kunzao and bacteria. In addition to disinfection, it is also used in agriculture to control smut by soaking wheat seeds in formalin. Paraformaldehyde, a polymer of formaldehyde, is used as fumigant in warehouse. Formaldehyde alcohol solution can be used for many special purposes, especially in the manufacture of some resins, the step of dehydration from the resin can be omitted. Formaldehyde through methylation, chloromethylation, Cyanomethylation, hydroxymethylation, cyclization, condensation and other operations can provide many intermediates for the production of pesticides, pharmaceuticals, dyes, spices, textile finishing agents, chelating agents, adhesives and other fine chemicals
Analysis and determination of ammonium salts and amino acids, microscopic analysis of various preparations of fixatives, disinfectants, fungicides, reducing agents.
