Preparation By Halogen Addition TRIZ Cases
- Hydrofluorination of Chlorotrifluoropropene for High Single-Pass Conversion
Catalyst-driven hydrofluorination raises single-pass conversion of chlorotrifluoropropene, easing difficult product separation and reducing equipment scale.
- Chlorofluorobutane Conversion with ClF for By-Product Recovery
ClF converts pentachloropentafluorobutane by-products into the target fluorochemical, improving selectivity, yield, and waste reduction.
- Photochlorination of Chloromethanes for High-Selectivity Carbon Tetrachloride
Stoichiometric chlorine and electromagnetic radiation reduce heavy chlorinated byproducts, enabling direct downstream use.
- 2-Fluorobutane Purification via Bromonium Ion Formation
Bromonium ion formation transforms gaseous butene into non-volatile derivatives, enabling high-purity 2-fluorobutane recovery without decomposition.
- Fluorinated Olefin Synthesis via Metal Fluoride Catalysts
Metal fluoride catalysts convert fluorinated alkanes to olefins while suppressing flammable 3,3,3-trifluoropropene byproduct formation.
