Solvent Properties
Filter solvents by boiling point, polarity, miscibility and price.
How to use this tool
Compare common lab solvents side by side and narrow the choice for an extraction, recrystallisation or column, by boiling point, polarity and whether they mix with water.
What to enter
- Water-miscibility filter: show all solvents, only water-miscible ones, or only water-immiscible ones.
- Sort by: order the table by polarity index (P′), boiling point, density or name.
Reading the result
A table of boiling point (°C), Snyder polarity index P′, density, water-miscibility and solvent class (non-polar, polar aprotic, polar protic). Lower P′ means less polar; a low boiling point is easier to remove on the rotovap.
Worked example
Sort by polarity and the list runs from n-pentane (P′ 0.0, non-polar) up to water (P′ 9.0); filter to water-immiscible to find a partner for a liquid–liquid extraction.
Columns
BP = boiling point (°C). Polarity index (P′) follows Snyder. Density at 20–25 °C (g/mL). Water-miscibility is qualitative. "Class" groups by behaviour (non-polar, polar aprotic, polar protic). Sort by any column and filter by water-miscibility to narrow a solvent choice for extraction, recrystallisation or chromatography.
