Formaldehyde is a naturally occurring organic compound with the formula CH2O (H-CHO). It is the simplest of the aldehydes (R-CHO). The common name of this substance comes from its similarity and relation to formic acid.
Formaldehyde is an important precursor to many other materials and chemical compounds. In 1996, the installed capacity for the production of formaldehyde was estimated to be 8.7 million tons per year. It is mainly used in the production of industrial resins, e.g., for particle board and coatings.
Formalin 37% and 42% are produced by oxidation of methanol. There are made of 37% and 42% formaldehyde gas in water and impurities such as methanol, small amounts of formic acid, aldehydes and ketones.
Formaldehyde is more complicated than many simple carbon compounds in that it adopts several different forms. As a gas, formaldehyde is colorless and has a characteristic pungent, irritating odor. Upon condensation, the gas converts to various other forms of formaldehyde (with different chemical formulas) that are of more practical value. One important derivative is the cyclic trimer metaformaldehyde or 1,3,5-trioxane with the formula (CH2O)3. There is also a linear polymer called paraformaldehyde. These compounds have similar chemical properties and are often used interchangeably.
Used as disinfectant; germicide and fungicide for plants,vegetables;Manufacture of phenolic,urea formaldehyde and melamin formaldehyde resins, artificial silk and cellulose esters,dyes, organic chemicals,glass mirrors,explosives;tanning and preserving hides. Also used for mordanting (improving fastness of dyes)on fabrics;preserving and coagulating rubber latex;in embalming fluids.In photography for hardening gelatin plates and papers,toning gelatin-chloride papers,chrome printing and developing.To prevent mildew and spelt in wheat and rot in oats;to render casein,albumin and gelatin Insoluble;also as laboratory chemical.Formaldehyde is flammable in the presence of sparks or open flames.
