Tetrahydrofuran Hydrate Crystal Growth Inhibitor Performance and Mechanism of Quaternary Ammonium and Phosphonium Salts

Crystal Growth & Design, 2020
To gain insight into the hydrate crystal growth inhibitor (HCGIs) mechanism, we have studied various quaternary ammonium ionic liquid salts (QAILs) and phosphonium salts for their ability to preven...

Phosphonium Salt Organocatalysis

Advanced Synthesis & Catalysis, 2009
AbstractThe field of organocatalysis is growing rapidly and attracts an increasing number of research groups. Most organocatalysts can be classified as Lewis bases, Lewis acids, Brønsted acids and Brønsted bases. However, examples of Lewis acid organocatalysis under homogeneous conditions are comparatively rare.

Phosphonium salt intercalated montmorillonites

Applied Clay Science, 2009
Abstract Tri-phenyl vinylbenzyl phosphonium chloride and tetraoctyl phosphonium bromide salts have been used as intercalant agents for Na-montmorillonite. Fourier Transform Infrared spectroscopy (FTIR) and Thermogravimetric Analysis coupled with Mass-spectrometry (TG/DTG-MS) were used to characterize the modified montmorillonites and the thermal ...
