Discussion of Industrial Synthetic Routes to Hexafluoro-1,3-butadiene, C4F6 by Robert G. Syvret, Ph.D., ACSF

Various synthetic routes are known for the formation and industrial scale production of hexafluoro-1,3-butadiene (HFBD), C4F6.  This document provides a brief overview and comparison of the key attributes of the most prominent industrial routes.  A preferred and advantageous route to C4F6, involving addition of the interhalogen, ICl, to chlorotrifluoroethylene (CTFE) followed by subsequent coupling and dehalogenation … Continued

Krypton in the Lighting, Windows, and Medical Industry

Lights, action, camera: it’s time to celebrate krypton for its contribution to lighting, energy-efficient windows, and diagnostics in the medical industry. Stronger Light When you ionize Krypton, you get a strong white light—which makes it an excellent choice for flashbulbs (remember those?), fluorescent lamps, airport runway lights, lasers (as krypton plasma) for laser shows, and … Continued
