Thermomorphic
Webb24 juni 2015 · To allow catalyst separation, we develop a thermomorphic system that employs lipophilic ligands that are soluble in a low-polarity phase and immiscible with methanol at room temperature. Lower alkanes and decalin are too miscible with methanol to allow effective catalyst recycling, but mineral oil (nujol) is very effective.

Thermomorphic system To eliminate the need to recover the product by distillation, researchers are now looking at thermomorphic solvent mixtures. A thermomorphic system is characterized by solvent pairs that reversibly change from being biphasic to monophasic as a function of temperature. Webb27 mars 2024 · The article reports test data on adsorption and flotation characteristics of thermomorphic polymer joined with diphenylphosphine—TMPD. The test materials are natural pyrite and arsenopyrite, and models of gold-bearing sulfide minerals. Electron microscopy and X-ray structure analysis prove that reductive adsorption of gold at the …

WebbA thermomorphic ionic-liquid-based microemulsion system was successfully applied for the Ru-catalyzed asymmetric transfer hydrogenation of ketones. On the basis of the temperature-dependent multiphase behavior of the targeted microemulsion, simple product separation as well as catalyst recycling could be realized. The use of water-soluble …
