Preparation By Halogen Replacement TRIZ Cases
- Bromochloromethane Preparation with Catalytic Phase Separation
Catalyst selection plus water or alcohol phase splitting raises bromochloromethane yield and enables cleaner, simpler separation.
- HFC-23 Recycling Catalyst Composition for Stable Low-CFC-12 Conversion
Metal oxide additives stabilize HFC-23 recycling catalysts and cut CFC-12 by-product formation while preserving HCFC-22 selectivity.
- 17-Methylalkane Synthesis via Distillable Halo Intermediate
A distillable 1-halo-7-methyltricosane intermediate enables scalable, high-yield 17-methylalkane synthesis without chromatography.
