Chromium Trioxide (CrO 3) Chromium trioxide is a strong oxidizing agent that is not soluble in most organic solvents and tends to explode in the presence of organic compounds and solvents. In water, it forms chromic acid and anhydrides, from which salts such as sodium dichromate (Na 2 Cr 2 O 7 ) and pyridinium dichromate are commercially available.

酸化クロム(VI)（さんかクロム ろく、英: chromium(VI) oxide ）または三酸化クロム（さんさんかクロム、英: chromium trioxide ）は、化学式 CrO 3 で表される無機化合物である。クロム酸の酸無水物で、同名で市販されることもある 。

It is also known by trade names, such as Chromic acid, chromic anhydride, and Chromium VI Oxide. It is dark-purple solid under anhydrous conditions, bright orange when wet and which dissolves in water concomitant with hydrolysis. Chromium trioxide, chromic acid These corrosion data are mainly based on results of general corrosion laboratory tests , carried out with pure chemicals and water solutions nearly saturated with air (the corrosion rate can be quite different if the solution is free from oxygen). Chromium trioxide (CAS NO.10043-01-3) is highly toxic, corrosive and carcinogenic. It is the main example of the environmental hazard known as "hexavalent chromium". The related chromium (III) derivatives are not particularly dangerous, thus reductants are used to destroy chromium(VI) samples.

This compound is a dark-purple solid under anhydrous conditions, bright orange when wet Chromium trioxide decomposes above 197°C liberating oxygen eventually giving Cr 2 O 3. The reaction of chromium trioxide with organic substances is potentially explosive. In spite of this, CrO 3 is used in organic chemistry as an oxidant, often dissolved in acetic acid , [2] or acetone in the case of the Jones oxidation . Chromium trioxide dossier. In June 2015, chromium trioxide was detected in old layers of paint on some of our trains. As soon as this was discovered, employees, the works council, trade unions and ISZW (formerly known as Arbeidsinspectie) were informed.

Chromium trioxide is listed in Annex XIV to REACH (Regulation (EC) No 1907/2006), as it is both carcinogenic and mutagenic. Consequently, it is considered to be a substance of very high concern and is subject to the authorisation requirement under REACH. Therefore, companies who use this substance must apply for authorisation.
