Brin process

Chemistry
  • A process formerly used for making oxygen by heating barium oxide in air to form the peroxide and then heating the peroxide at higher temperature (>800°C) to produce oxygen

    2BaO22BaO+O2

    The process is named after the French chemists Quentin and Arthur Brin, who showed how to make it commercially viable in 1879.


Chemical Engineering
  • A process that was once used for producing oxygen through the heating of barium oxide in air to form barium peroxide. This was then heated to temperatures in excess of 800°C to produce oxygen:

    2BaO22BaO+O2

    The reaction was discovered by the French chemists Joseph-Louis Gay-Lussac (1778–1850) and Louis-Jacques Thénard (1777–1857). The process was particularly inefficient, and a major improvement was developed by Arthur and Leon Brin who found a way of removing the carbon dioxide with sodium hydroxide. The oxygen produced was used for limelight before more cost-effective methods of producing oxygen were discovered.
