In formaldehyde aqueous solution, formaldehyde concentration is 30%-50%,methanol content(0-12%). Formaldehyde is a gas with strong irritating smell, generally existed as aqueous solution, when the concentration of formaldehyde vapor reaches 1mg/l it will irritate the eyes, nose, throat and lungs. Contact with formaldehyde solution may cause eye burning, skin allergy. It tends to auto-polymerization to form white pasty polyformaldehyde deposit when stored at low temperature or for a long period with high concentration. If formaldehyde is contained in iron drums without adequate anti-corrosion protection, part of the formaldehyde will be oxidized into formic acid with the presence of iron ions and the solution will become yellow. The chemical property of formaldehyde is very active and the reactions of addition, condensation, polymerization, oxidation, carbonylation can occur, it is one of the basic raw materials for organic synthesis.


Besides being used as medical disinfectant and preservative, formaldehyde is mainly used in production of urea-formaldehyde resin, melamine resin, carbamate formaldehyde resin, cyanamide and dicyanamide formaldehyde resin, sulfamide formaldehyde resin, aniline formaldehyde resin, phenol formaldehyde resin, polyformaldehyde resin, pentaerythritol, urotropine, 1,4-butanediol, pesticide, fertilizer, medicine, explosive, dye, coating, vinylon fiber etc. It can also be used in timber machining, soil disinfection, finishing agent for paper and leather, fumigation and desinfection of warehouse and so on.
