Preparation By Hydrogen Halide Split-Off TRIZ Cases
- Vinyl Chloride Production via Liquid Heat Transfer Medium
Liquid heat transfer medium enables catalytic 1,2-dichloroethane cracking at lower temperatures to cut CO2 emissions and operating costs.
- Manufacturing Fluoroolefin Refrigerant via Catalytic Hydrogenation
A catalytic process converts CF3CF=CHF to CF3CF=CH2 using hydrogenation and dehydrohalogenation steps.
- Continuous Trifluoroethane Reactor with Rotary Cutting and Flow Deflector
A continuous reaction apparatus uses a rotary cutting component and offset flow deflector plates to enhance mixing efficiency.
- Acetylene Vinyl Chloride Synthesis Using Activated Carbon Catalyst
Activated carbon-supported barium salt catalyst enables efficient vinyl chloride synthesis from acetylene and dichloroethane.
- Dehydrofluorination Catalyst for HFC-1234yf and HFC-1234ze Production
Dehydrofluorinating HFC-245eb with fluorided alumina yields HFC-1234yf and HFC-1234ze, enabling recovery via HF azeotropes to address low ozone depletion needs.
- Catalytic Dehydrochlorination Selectivity via Metal Halides
Composite metal halide catalysts suppress competing dehydrofluorination reactions, boosting single-pass productivity and yield of fluorinated olefins.
- HFC-143 Production via HCFC Fluorination and Catalyst Optimization
Fluorinate HCFC-142 with excess hydrogen fluoride over chromium oxide catalysts to lower production costs compared to chlorotrifluoroethylene routes.
