How do I prepare formaldehyde industrially?

Formaldehyde & derivatives

Formaldehyde is one of the most important organic raw materials in the chemical industry. It is colorless, has a pungent odor, easily soluble in water and its boiling point is -19 ° C.

In nature, formaldehyde is produced as an intermediate product in normal metabolism. The adult organism forms around 50 g of formaldehyde daily and breaks it down again. Formaldehyde is an important raw material for the chemical industry and the basis for many industrial products. Over 50 branches of industry use formaldehyde and its derivatives, as adhesives, resins and in many other areas of application.

The worldwide annual consumption of formaldehyde is around 41 million tons. 51% of it is produced in China. Pörner Grimma is not only a specialist in the formaldehyde process, but also in process applications for formaldehyde derivatives.

Technically, formaldehyde can be produced through the catalytic oxidation of methanol. Two methods are suitable for this, the silver catalyst and the metal oxide catalyst method.

Although the catalyst has to be changed more frequently in the silver catalyst process, the aqueous formaldehyde solution is of higher quality because the formic acid content is lower.

Formalin, a formaldehyde solution diluted with water, has been used for the preservation of organic preparations since the 19th century. But foramlin is also used in the initial steps for the plasticization of human specimens.
