Application

Chlorine gas has been used to generate chlorine atoms via photolysis for molecular halogen photochemical experiments.

It can be used:
  • As a reactant for the extraction of gold from an alluvial material via a pyrometallurgical process.
  • To synthesize carbide-derived carbons (CDC) from zirconium carbide.

Packaging

Supplied in a carbon steel lecture bottle with a CGA180M/CGA110F needle valve installed.

Compatible with the following:
  • Aldrich® lecture-bottle station systems
  • Aldrich® lecture-bottle gas regulators
