Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

vapour pressure
Data waiving:
study technically not feasible
Justification for data waiving:
Justification for type of information:
The target substance is hydrolytically unstable with hydrolysis half-life less than 5 minutes. The hydrolysis products have been identified to be 1-butanol and hydrated zirconium dioxide. The vapour pressure test may lie on the property of 1-butanol
vapour pressure
Type of information:
experimental study
Adequacy of study:
key study
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
data from handbook or collection of data
Justification for type of information:
1-butanol is the main hydrolysis prodcuts of the target substance. Properties of the hydrolysis are used for read-across.
other: not specified.
GLP compliance:
not specified
Type of method:
other: not specified.
Key result
ca. 20 °C
Vapour pressure:
ca. 0.56 kPa
The vapor pressure of 1-butanol is 0.56 kPa at 20°C according to published data.
