weight of evidence

Study period:

no data

Reliability:

1 (reliable without restriction)

other: Study reported in the 2004 SIDS dossier. Reliability score 1: Meets generally accepted scientific standards and is described in sufficient detail.

Qualifier:

no guideline followed

Principles of method if other than guideline:

A dynamic technique was used to determine the vapor pressure (20-760 mmHg) in a tein ebulliometer using diphenyl oxide as the reference sample. The boiling temperatures of diphenyl oxide and the sample were measured with platinum resistance thermometers connected to a Leeds and Northrup high precision range changing resistance recorder.

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.
