Halogenated Hydrocarbon Preparation TRIZ Cases
- Extractive Distillation of Hexafluoropropylene Oxide Using Fluorinated Solvents
Fluorinated solvents replace ozone-depleting chlorine compounds in extractive distillation, increasing relative volatility to purify hexafluoropropylene oxide.
- Dimethyl C17-32-Alkyl Sulfonium Chloride Synthesis via Alkyl Chlorides
Replacing alkyl iodides with stable alkyl chlorides eliminates toxic reagents and light sensitivity while achieving high yields.
- Onium Chloride Chlorination of Perfluoroallyl Fluorosulfate
Direct chlorination of perfluoroallyl fluorosulfate using onium chloride compounds to produce 3-chloro-pentafluoropropene in a single step.
- Fluidized Bed Reactor Heat Recovery via Boiler Feed Water Recirculation
A fluidized bed reactor recirculates heated boiler feed water to dissipate reaction heat from ethylene oxychlorination.
- Terminally Iodized Polyfluoroalkane Production via Low-Temperature Telomerization
Using peroxide initiators for low-temperature telomerization reduces energy consumption and facility corrosion while limiting bioaccumulation potential.
- Pentabromobenzyl Aromatic Flame Retardants Reducing Volatility
High molecular weight pentabromobenzyl aromatic compounds provide stable flame retardancy in polymers.
