This table summarizes the properties of 574 liquids that are commonly used in the laboratory as solvents or chemical reagents. Column definitions for the table are as follows.
Column heading | Definition |
Name | Name of solvent or reagent; liquids are listed in alphabetical order by name |
Synonym | A synonym in common use. When the primary name is non-systematic, a systematic name may appear here |
Mol. form. | Molecular formula of solvent or reagent |
CAS Reg. No. | Chemical Abstracts Service Registry Number for the compound |
Mr | Molecular weight |
tmp | Melting point, in °C |
tbp | Normal boiling point, in °C |
ρ | Density in g/mL at the temperature in °C indicated by the superscript |
n | Refractive index at the temperature in °C indicated by the superscript |
ε | Dielectric constant (permittivity) at the temperature in °C indicated by the superscript (otherwise at ambient temperature) |
μ | Dipole moment in Debye units |
cp | Specific heat capacity of the liquid at constant pressure at 25 °C in J/g K |
η | Viscosity in mPa s (1 mPa s = 1 centipoise) at 25 °C |
Pvap (25 °C) |
Vapor pressure at 25 °C in kPa (1 kPa = 7.50 mmHg) |
tFP | Flash point in °C |
Flam. limits | Flammable (explosive) limits in air in percent by volume |
tIT | Autoignition temperature in °C |
TWA and STEL | Threshold limits for allowable airborne concentration in parts per million by volume at 25 °C and atmospheric pressure. TWA refers to a 8-hour time-weighted average and STEL to a short-term limit. More details on threshold limits can be found in Section 16. |
Data on the temperature dependence of viscosity, dielectric constant, and vapor pressure can be found in the pertinent tables in Section 6.
