[资源] 575种实验室常用试剂的物性参数（crc）

This table summarizes the properties of 575 liquids that are commonly
used in the laboratory as solvents or chemical reagents.

The properties tabulated are:
Mr : Molecular weight
tm: Melting point in °C
tb : 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
cp: 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.
