Chromium trioxide is also considered highly toxic for aquatic and marine environments. Given such toxicity concerns, the use of chromium trioxide for industrial purposes is subject to various regulations, such as the EU Directive 2004/37. Chromium trioxide is also know by trade names, such as chromic anhydride and Chromium VI Oxide.

Chromium trioxide is highly corrosive and is a strong oxidizing agent. This substance is mainly used in the production of wood preservatives and organic chemicals, but is also used in metal finishing and chrome plating and as a corrosion inhibitor. chromium (VI) trioxide - Substance Information - ECHA NB: Registration status and tonnage The REACH Registered substance portal was updated on 9th November 2020; the REACH registered factsheets were further updated on 21st December 2020. Details of the improvements can be found at Dissemination Platform Updates.

on the draft Commission implementing decision partially granting an authorisation for a use of chromium trioxide under Regulation (EC) No 1907/2006 of the European Parliament and of the Council (Cromomed S.A. and others) 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; Description. 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.
