一般說明

Cesium hydroxide is a strong base that can be used in organic synthesis, as a catalyst, and as an intermediate in the production of cesium compounds.

應用

Cesium hydroxide monohydrate can be used:

  • As a catalyst to prepare unsymmetrical Bis-allyl ethers via dimerization of Baylis-Hillman adducts.
  • As a dopant to fabricate vanadium oxide thin films as a hole extraction layer for perovskite solar cells.
  • As an initiator for ring opening polymerization of monosubstituted oxiranes.
  • As a promoter to synthesize secondary amines via chemoselective N-alkylation.

(13)C metabolic MRI using hyperpolarized (13)C-bicarbonate enables preclinical detection of pH. To improve signal-to-noise ratio, experimental procedures were refined, and the influence of pH, buffer capacity, temperature, and field strength were investigated. Bicarbonate preparation was investigated. Bicarbonate was prepared and

Electrolysis is omnipresent in all electrochemical processes including electromembrane extraction (EME). The effects of electrolysis on quantitative aspects of EME were comprehensively evaluated for a set of acidic (substituted phenols) and basic (basic drugs) analytes. EMEs were carried out across
