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

In nature, formaldehyde is formed as an intermediate in the normal metabolism. The adult organism produces about 50 grams of formaldehyde daily.

Formaldehyde is an important raw material for the chemical industry and the basis for many industrial products. More than 50 branches of industry using formaldehyde and its derivatives, as adhesives, resins, and in many other applications. The global annual consumption of formaldehyde is about 41 million tons. 51% of them are made in China.

Pörner Grimma is not only a specialist in the formaldehyde method, but also for process applications of formaldehyde derivatives. Technically formaldehyde can be produced by the catalytic oxidation of methanol. These are, two methods, the silver and the Metal Oxide method.

Although the catalyst has to be changed frequently in the silver method, but the aqueous formaldehyde solution is of higher quality because the formic acid content is lower. Formalin, a solution made of diluted formaldehyde and water has been used since the 19th century for the preservation of organic products. It has also been used for the plasticizing of human bodies for both scientific as well as learning applications.

Formaldehyde vs. Formalin

There has always been confusion as to the different terms, formaldehyde and formalin. Formaldehyde is a gas in its natural state of aggregation, whereas formalin is the aqueous solution of formaldehyde which is stabilized in order to avoid polymerization with 5-15% methyl alcohol. Formaldehyde can be produced industrially by the catalytic oxidation of methanol.
