Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information

Compilation of vapour pressure data on 1,2,3 -Trichloropropane from different handbook sources:

 Data source  Vapour pressure in hPa  Temperature in °C
 Lide 1995 (CRC Handbook)  4.92  25
NITE 2009 (data bank)  4.89   25
  Dow 1984 (study report)  6.65  32.84 
  Lide 2008 (CRC Handbook)   10   37

Vapour pressure data from three phys-chem. handbooks and from one study report of The Dow Chemical Company were being evaluated. The above table indicates that the values from the different sources are consistent and that therefore the data set can be considered as robust. Lide 2008 and Dow 1984 even give the whole vapour pressure curve. Since the 1984 study of Dow is rated as Klimisch 1, the value given there is highlighted above. The vapour pressure of 1,2,3-Trichloropropane is 6.65 hPa (5 mm Hg) at 32.84 °C.
