Acta Chemica Scandinavica

1.2. Recommended use and restrictions on use This compound is a dark-purple solid under anhydrous conditions, bright orange when wet and which dissolves in water concomitant with hydrolysis. Millions of kilograms are produced annually, mainly for electroplating. Chromium trioxide is a powerful oxidiser and a carcinogen .

Dark, violet-red deliquescent crystals. Chromium trioxide is normally used as an aqueous solution which is commonly called Chromic acid.Chromic acid is made by mixing Potassium dichromate and an acid such as Hydrochloric acid or Sulfuric acid. This chromium trioxide/acetone/sulfuric acid reagent is often referred to as the Jones reagent, and oxidation of alcohols with this reagent is called Jones oxidation. 48 Jones oxidation is especially useful for molecules that contain alkenyl or alkynyl groups. 49 Oxidation of alcohols is usually faster in acetone than in acetic acid, and using a large excess of acetone protects the ketone Authorization of chromium trioxide – Requirements to be fulfilled by the downstream user.

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 monograph for Chromium Trioxide provides, in addition to common physical constants, a general description including typical appearance, applications, change in state (approximate), and aqueous solubility. The monograph also details the following specifications and corresponding tests for verifying that a substance meets ACS Reagent Grade specifications including: Assay, Insoluble Matter B. whereas chromium trioxide was included in Annex XIV to the REACH Regulation in 2013 (6) due to that classification, the high volumes currently in use, the high number of sites where it is used in the Union and the risk of significant exposure to workers (7), with a sunset date of 21 September 2017; 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). The risk assessment is based on current practices related to the life-cycle of the five related chromium (VI) substances, chromium trioxide, ammonium dichromate, potassium dichromate, sodium chromate and sodium dichromate produced in or imported into the European Community as described in the risk assessment forwarded to the Commission by the Member State Rapporteur (2 ).

It is the acidic anhydride of chromic acid, although in the general market place, the names are often used interchangeably. It is frequently used in the electroplating industry. 2020-11-18 · Chromium trioxide is an inorganic compound having the chemical formula CrO3. It is the acidic anhydrous form of chromic acid. Therefore, both these substances are sometimes available in the market under the same name.
