Sulfonic Acid Preparation TRIZ Cases
- Spirocyclic Ammonium Salt Composition for Lower Melting Points
Exocyclic substituents and tailored anions lower spirocyclic ammonium salt melting points while preserving catalytic and electrochemical use.
- Alkanesulfonic Acid Reactor Cascade for Higher MSA Yield
Staged initiator dosing in a reactor cascade raises MSA yield while limiting sulfuric acid byproduct and waste in alkanesulfonic acid production.
- 3,5-Di-Tert-Butylbenzenesulfonic Acid Process With HCl Pretreatment
Anhydrous HCl pretreatment suppresses sulfonation side-products, enabling high-purity 3,5-di-tert-butylbenzenesulfonic acid by filtration.
- Zwitterionic Liquid Dielectrics With High Permittivity at Room Temperature
Liquid zwitterions overcome the low rotational mobility of crystalline solids, delivering tunable high dielectric constants for capacitors, actuators, and ion transport.
