Reference
Endpoint:
Henry's law constant
Type of information:
(Q)SAR
Adequacy of study:
supporting study
Reliability:
4 (not assignable)
Rationale for reliability incl. deficiencies:
results derived from a (Q)SAR model, with limited documentation / justification
Qualifier:
no guideline followed
Principles of method if other than guideline:
Estimation of the Henry's Law Constant (HLC) with the PC programme HENRY (v3.10, bond estimation method)
GLP compliance:
no
H:
0.023 Pa m³/mol
Temp.:
25 °C
Atm. press.:
1 013 hPa
Conclusions:
The HLC of butane-1,3-diol was estimated to be 0.0233 Pa m³/mol at 25°C.
Executive summary:

Based on a calculated HLC of 0.0233 Pa m³/mol (25 °C), 1,3 -butanediol is considered to have low potential for volatilization from water.

Description of key information

HLC = 0.0233 Pa*m³/mol at 25 °C (calculated; ECT, 2008). 

Key value for chemical safety assessment
