Unformatted text preview: LABORATORY SOLVENTS AND OTHER LIQUID REAGENTS This table summarizes the properties of 575 liquids that are com- monly used in the laboratory as solvents or chemical reagents . The properties tabulated are: M r : Molecular weight t m : Melting point in °C t b : Normal boiling point in °C ρ : Density in g/mL at the temperature in °C indicated by the superscript η : Viscosity in mPa s (1 mPa s = 1 centipoise) ε : Dielectric constant at ambient temperature (15 to 30°C) μ: Dipole moment in D c p : Specific heat capacity of the liquid at constant pressure at 25°C in J/g K vp: Vapor pressure at 25°C in kPa (1 kPa = 7 .50 mmHg) FP: Flash point in °C Fl .Lim: Flammable (explosive) limit in air in percent by volume IT Autoignition temperature in °C TLV Threshold limit for allowable airborne concentration in parts per million by volume at 25°C and atmospheric pressure Data on the temperature dependence of viscosity, dielectric constant, and vapor pressure can be found in the pertinent tables in this Handbook References 1 .
