Solvent power
WebThe “eluting power” of a solvent is largely a measure of how well the solvent can "pull" an analyte off the adsorbent to which it is attached. This often happens when the eluent adsorbs onto the stationary phase, displacing the analyte. Such series are useful for determining necessary solvents needed for chromatography of chemical compounds. WebSolvent Choice for Microwave Synthesis. The more efficient a solvent is in coupling with the microwave energy, the faster the temperature of the reaction mixture increases. Solvents play a very important role in organic synthesis. Most reactions take place in solution, and therefore, choice of solvent can be a crucial factor in the outcome of a ...

The Kb test is one of a number of “cloud-point” determinations that can be used to order solvents in a ranking based on relative solvent power. Other cloud-point determinations are aniline cloud-point, solubility grade, wax …
WebJun 1, 2006 · The solvency power of industrial solvents is often reported as a K-B or Kauri-Butanol value. The higher this value, the higher the solvency power is for a given solvent. This value required for a given formulation is usually a function of the binder system in the paint. A solvent such as toluene will have a higher K-B value than something like ...
