HSP Application note #24

Functional Groups that can use in HSPiP

2010.3.21

HSPiP Team Senior Developer, Dr. Hiroshi Yamamoto

 

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.
The 4th Edition v4.0.x was released on 2 Jan. 2013.
The v4.1.x was released on 18th Aug. 2013

The Current users can upgrade with free charge.

2013.1.28 The Visual How to manual of HSPiP. You can understand what HSPiP can do.

How to purchase HSPiP
2013..1.2 The HSPiP ver. 4 include Power Tools for HSPiP power user.

Functional Group s (FG) used in version 3 (to ver. 4.1.x). Y-Predict use same FG.
Please check your compound whether all of functional groups are in the list.

Y-MB break molecule as to below list.
Y-MB choose larger FG if it available.
Y-MB can not handle charged atoms like N+, Cl-.

@ mark means Attach to.
# means triple bond.

P is parameter missing for HSP

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

If you want to ask me to add new FG, please send me, at least, density, vapor pressure data, heat of vaporization, Refractive Index, Dipolemoment, dielectric constant for that molecule.

For Y-predict user. 2013.9.7

The Functional Group list is same with Y-MB.
There is one discussion about 3s_Ph or pyridazine compounds. For 3s_Ph, there are 1-2-3, 1-2-4, 1-2-5, 1-3-5 substitutions. But Y-MB and Y-Predict treat just same 3s_Ph. Some case, substitution position may change some properties, but to increase FG I need so many data but hard to get them.

For Y-Predict, I put the QEQ charge calculation function.

For these 3 compounds, FG list are same (N=_reso 2 , CH=_reso 4). But as you see, Nitrogen atom's charge are different (-0.045, -0.105, -0.064). So it means tree types of N=_reso exist. And in the calculation result, there is term of Symmetry Index. First and third molecule has 100% Symmetry, but second molecule is not 100% Symmetry. This Symmetry is "charged base" symmetry.The Max Plus Charge, Minimum Minus Charge are also different to these 3 molecules.

Application of these chrages and Symmetry to properties estimations scheme is just starting. If I find rational way to use of these Indexes, I will put them in new version.
