HSPiP(Hansen Solubility Parameters in Practice)

The first edition of HSPiP that appeared in November, 2008, greatly enhanced the usefulness of the Hansen solubility parameters (HSP).

The HSP values of over 1200++ chemicals and 500 polymers are provided in convenient electronic format and have been revised and updated using the latest data sources in the second edition (March, 2009).

A third edition of the HSPiP appeared in March, 2010. There are now 10,000 compounds in the HSP file which also includes data on density, melting point, boiling point, critical parameters, Antoine constants and much more. The user is able to carry out many different sorts of optimisations of solubility, evaporation, diffusion, adhesion, create their own datasets (automatically if required) and explore the huge range of applications for HSP in coatings, paints, nanoparticles, cosmetics, pharma, organic photovoltaics and much more.

The 3rd Edition v3.1 was released on 12 December 2010. Current users can upgrade free (now v3.1.09) by downloading the latest .msi installer from http://hansen-solubility.com

Nitrile group is very difficult group. The properties are very depend on attached groups. We recommend only alkane or Aromatic attached nitrile.

Acid anhydride groups, Carbonate groups

167	O@AR	104	OO	156	O_EPO
122	O@N			135	O:

Ether attached to halogen groups, especially CF2,
that loss ether properties.

119	S:	108	S_reso
		127	S{:O}2

SO2 group attach to NH2 or NH, the properties are similar to Amide.
But in ver. 3 we use just SO2+NH2.

C:_reso means resonance carbon connect to alkane carbon.
CH:_reso means resonance carbon connect to hydrogen.
C:_rrr means resonance carbon like the naphthalene center 2 carbon.
Xs_Ph: means X substitute.

P is parameter missing for HSP

If we increase Functional Groups, properties estimation accuracy will increase.
But Functional Groups number increase, we need more and more data.

Please check your compound whether all of functional groups are in the list.
If some of the functional groups are missing, please let us know.

Actually, for estimation of HSP, version 2 functional groups are enough.
But for other properties estimation, version 3 functional groups breaks are very needed.
