Download
In addition to searching and browsing online, there are two options to
download all Henry's law constants in machine-readable format:
PostgreSQL
The zip archive
henry_4.0.2_sql.zip
contains the whole database
in PostgreSQL syntax.
Fortran90
The zip archive
henry_4.0.2_f90.zip
contains Fortran90 files defining several variants of the
Henry's law constants. Code snippets from these files can be used via
'copy and paste'. For example, oxygen values are represented in
HscpSI.f90 as:
! species: oxygen
! formula: O_2
! trivial:
! casrn: 7782-44-7
! inchikey: MYMOFIZGZYHOMD-UHFFFAOYSA-N
HscpSI____7782_44_7 = 1.2E-05 * EXP(1700.*(1./T-1./298.15))
! [mol/(m^3~Pa)] type: L, ref: 2828
...
HscpSI____7782_44_7 = 1.3E-05 * EXP(1400.*(1./T-1./298.15))
! [mol/(m^3~Pa)] type: M, ref: 491
...
HscpSI____7782_44_7 = 1.3E-05
! [mol/(m^3~Pa)] type: ?, ref: 523
...
For each value, a reference number is added as a comment. The full
references can be found in the
BibTeX file
henry.bib, which is also included in the zip archive.
