Introduction

The Beilstein database contains information on substances, including coverage of reactions, structures and properties. Up to 350 fields containing chemical and physical data (such as melting point, refractive index, and so on) are available for each substance. References to the literature in which substance data appears are also given.

Test for Halogens Using Pyrolysis (BEILSTEIN TEST) Principle Involved: A material containing bound or ionic halogens (chlorine, bromine, iodine) such as salt or polyvinyl chloride (PVC), will react with a copper wire when heated in a flame and produce a brilliant, long lasting green flame.

2 C u ( s) + O X 2 ( g) 2 C u O ( s) Then when you mix it with the halide and heat it, the higher reduction potential makes it displace the oxygen. Here's an example with sodium chloride: C u O ( s) + 2 N a C l ( s) C u C l X 2 ( g) + N a X 2 O. Copper halides are volatile (except for fluorides); the gas is hot enough to push some electrons ...

Beilsteins test er en enkel kjemisk prøve brukt i kjemien som en kvalitativ prøve på halogener. Den ble utviklet av Friedrich Konrad Beilstein. I en test blir en kobbertråd renset og oppvarmet av en flamme fra en Bunsenbrennerfor å få et belegg av kobber(II)oksid. Den blir så dyppet i løsningen som skal testes og på nytt varmet i flammen. Dersom det er halogen i løsningen, vil det reagerer med kobberet, og flammen vil bli gr…

The Beilstein database is the largest database 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 reactions and substances from original scientific publications.

It was developed by Friedrich Konrad Beilstein. A copper wire is cleaned and heated in a Bunsen burner flame to form a coating of copper (II) oxide. 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.

To conduct the test, a piece of Copper wire or copper gauze placed in a flame to burn off impurities. When the flame shows no green, the copper ...

The Beilstein test confirms the presence of a halogen in solution, although it does not distinguish between chlorine, bromine, or iodine.
