Halogenated Hydrocarbon Preparation TRIZ Cases

Molten metal or alloy at 300-900°C boosts fluoropolymer pyrolysis, raising fluoromonomer conversion for more efficient recycling.

Organic sulfur compounds boost fluoropolymer pyrolysis, raising fluoromonomer conversion at moderate temperatures with simple kiln processing.

A hydrochloric acid and Lewis acid route converts triphenylmethanol cleanly, avoiding waste gas, corrosion, and low-yield side reactions.

A tuned resin molar ratio preserves low dielectric loss and heat resistance while preventing copper foil corrosion in high-frequency packaging.

Controlling distillation temperature, water, and acetic acid composition suppresses acetal formation and improves acetaldehyde removal.

Controlling gas and absorber temperature gaps during microwave fluororesin decomposition improves monomer selectivity in the output gas.

Zeolite with a controlled SiO2/Al2O3 ratio and pore size removes impurities from hexafluorobutadiene while suppressing isomerization.

Controlling the gap between microwave absorber, carrier gas, and outlet gas temperatures improves fluororesin decomposition selectivity and target yield.

A specific ionic catalyst drives olefin insertion into fluorinated organic iodine compounds, enabling mild, metal-free synthesis with cleaner copolymer end-group control.

Adding organic sulfur compounds improves fluoropolymer thermal decomposition, boosting fluoromonomer yield at lower temperatures.

Molten metal or alloy improves heat transfer during fluoropolymer pyrolysis, raising fluoromonomer conversion for recycling.
