Astrophysical Observatory. Why potassium carbonate cannot be prepared by Solvay process? For small fires involving beryllium chloride, extinguish with dry chemical, CO2, Halon , water spray, or standard foam, and for large fires, use water spray, fog, or standard foam. The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. Jmol.jmolLink(jmolApplet0,"select all;spacefill off; wireframe .1;","Sticks") Beryllium chloride a colorless crystal. The database represents a non-exhaustive list of such substances based on: 1) agents of risk groups 3 and 4 under Directive 2000/54/EC; 2) Table 3 of Annex VI to the CLP Regulation; 3) and Annex I of Directive 2004/37/EC. Note that this list is not exhaustive. (or is it just me...), Smithsonian Privacy Beryllium chloride is a Lewis acid and has been used as a catalyst in some organic reactions. The Support section provides tools and practical guidance to companies which have responsibilities under the EU chemicals legislation. Substances may have impurities and additives that lead to different classifications. Please be aware there may be intermittent unavailability while work in ongoing. document.write(" ") The structure of solid BeCl2 is an unusual chain polymer with two chlorine atoms bridging between the Be atoms. Why alkali metals are normally kept in kerosene oil? More information about CAS and the CAS registry can be found here. InfoCards are updated when new information is available. Please upgrade your Internet Explorer to a newer version. Some substance identifiers may have been claimed confidential, or may not have been provided, and therefore not be displayed. ECHA organises consultations to get feedback from all interested parties and to gather the widest possible range of scientific information for the regulatory processes. No votes so far! This information is only displayed if the substance is well-defined, its identity is not claimed confidential and there is sufficient information available in ECHA’s databases for ECHA’s algorithms to generate a molecular structure.
