Purified precursors from the KIMW-F

Due to global supply chain problems, the non-profit KIMW Forschungs-GmbH is now offering high-purity molybdenum hexacarbonyl (CAS 13939-06-5) and tungsten hexacarbonyl (CAS 14040-11-0) with a purity of up to 99.9 percent. The materials, which are essential for the production of complex injection mold surfaces, are available in quantities of 25 to 1,000 grams from the Lüdenscheid site.

Where are hexacarbonyls used?

Precursors such as molybdenum hexacarbonyl (CAS number 13939-06-5) and tungsten hexacarbonyl (CAS number 14040-11-0) are used in various branches of industry and are an indispensable component of defined processes. The product is generally used as a catalyst, e.g. to crack hydrocarbons or carry out organic syntheses. The ability of the product to decompose into molybdenum metal or similar reactive substances is interesting. It is therefore ideally suited to the production of thin coatings (thin film coating) using gas deposition processes, known by the abbreviation CVD coating. Typical areas of application here are toolmaking and the electronics industry. The product is therefore an important >component of processes for the semiconductor industry.

Production of metal carbonyls for almost 100 years

The processing of the production of metal carbonyls was mentioned in specialist literature in the 1930s to 1950s. Various sources reported on ways of producing the desired metal carbonyls with corresponding yields. The use of so-called autoclaves was of decisive importance. The reaction of metal chlorides to metal carbonyls is brought about with the help of increased pressure and temperatures.

The development and production of the corresponding autoclave technology was carried out by the KIMW research centre after intensive development work. To ensure safe operation and achieve a high degree of purity (99.9%), lengthy and complex investigations into the reaction kinetics were necessary. In particular, an understanding of the influence of the reactor geometry and the dynamic reaction control was developed so that a high degree of purification could be achieved.

The KIMW research center now makes it possible to supply purified metal hexacarbonyls to the European market at short notice.
