(EPA List of Lists, 2022) CISA Chemical Facility Anti-Terrorism Standards (CFATS) No regulatory information available. & indicates that no RQ is assigned to this generic or broad class, although the class is a CERCLA hazardous substance.Copper(II) chloride catalyzes the chlorination in the production of vinyl chloride and dichloroethane. The Deacon process takes place at about 400 to 450 C in the presence of a copper chloride: 4 HCl + O 2 2 Cl 2 + 2 H 2 O. 313c indicates that although not listed by name and CAS number, this chemical is reportable under one or more of the EPCRA section 313 chemical categories. Copper(II) chloride is used as a catalyst in a variety of processes that produce chlorine by oxychlorination.It is non-combustible but there are chances of formation of hydrogen chloride gas when heated. In its anhydrous form, it appears as a yellowish-brown powder whereas in its dihydrate form it appears as a green crystalline solid. Process Safety Management of Highly Hazardous Chemicals Standard ListĮPA Consolidated List of Lists Regulatory Name The molecular or chemical formula of Copper (II) Chloride is CuCl 2. Occupational Safety and Health Administration's Cybersecurity and Infrastructure Security Agency's Chemical FacilityĪnd the U.S. Environmental Protection Agency's Title III Consolidated List of Because sodium imparts an especially intense color to a flame, flashes of the sodium may be observed in nearly all solutions tested.The U.S. It should be noted that sodium is present as an impurity in many if not most metal salts. Copper (II) chloride, also referred to as Cupric chloride, or Copper dichloride, or Cupric dichloride, is a chemical compound with the formula CuCl 2.Copper dichloride takes place naturally as an anhydrous mineral called tolbachite and dehydrated eriochalcite.

A homemade atomizer was used to form a fine spray of the solution, which was sprayed directly into the burner flame. In these video sequences selected compounds, mostly metal salts, show the flame color in a Meeker burner flame. Some metal salts give off light outside of the visible region of the electromagnetic spectrum. Several metal salts give off a characteristic color visible to the human eye as is demonstrated by the alkali metals and a few other elements, but a fair number of metal salts give off light that may be observed, but is not sufficiently different in color to be differentiated from other metal salts. Upon returning to the ground state, they give off light (a line spectrum) characteristic of that metal. Used with palladium in a catalytic synthesis of 3-haloindoles via an annulation process. Metal ions combine with electrons in the flame and the metal atoms are raised to excited states because of the high flame temperature. Copper (II) chloride may be used in the preparation of copper (II)-chitosan complexes with potential applications in biomedical devices as antibiotic-free antibacterial biomaterials due to their cytocompatibility and antibacterial property. Metal salts introduced into a flame give off light characteristic of the metal. Copper(II) Chloride 2-hydrate (USP) pure, pharma grade Molecular Formula: CuCl2.2H2O Molar mass: 170.48 g/mol Melting Point: 100 C Solubility: water. These movies are 3 to 5 seconds in length. Aluminum chloride or magnesium chloride can be used to demonstrate that chlorine imparts no color to the flame.
