Refimprove date June 2009 The Beilsteindatabase is one of the largest Chemical databasedatabase s in the field of organic chemistry , in which compounds are uniquely identified by their Beilstein Registry Number . The database covers the scientific literature from 1771 to the present and contains experimentally validated information on millions of chemical reaction s and Chemical substance substances from original scientific publication s. The electronic database was originally created from Beilstein s Handbook of Organic Chemistry , founded by Friedrich Konrad Beilstein in 1881, but has appeared online under a number of different names, including Crossfire Beilstein. Since 2009, the content has been maintained and distributed by Elsevier Information Systems in Frankfurt under the product name Reaxys ref http www.reaxys.com info press room ref . The database contains information on reactions, substances, structures and properties. Up to 350 fields containing chemical and physical data such as melting point , refractive index etc. are available for each substance. References to the literature in which the reaction or substance data appear are also given. The Beilstein content made available through Reaxys ref cite web url http www.reaxys.com title Reaxys accessdate 4 January 2011 ref is complemented by information drawn from Gmelin which gives access to the Gmelin database Gmelin Database , a very large repository of Organometallic chemistry organometallic and inorganic chemistry inorganic information owned by the German Chemical Society Gesellschaft Deutscher Chemiker , as well as by information drawn from the Patent Chemistry Database.

It is then dipped in the sample to be tested and once again heated in a flame. A positive test is indicated by a green flame caused by the formation of a copper halide. This test is no longer frequently used. One reason why it is not widely used is that it is possible to generate the highly toxic Polychlorinated dibenzodioxins chloro dioxins if the test material is a polychloroarene . ref cite journal author Barbara M.
