Computed Property Data Base for Molecules (CPDB)

Japanese version

This data base contains molecular properties predicted by
property estimation methods. The properties and estimation methods are as follows:

1)Molecular Formura
Atom Groups separate by colon. Example CH2:Cl:CHF2 .
Not use wild card. If user want to search of words, you write in space.

2)Molecular Weight

3)Boiling Point(K)
Boiling Point(K) estimated by Joback Method.

4)Critical Temperature(K)
Critical Temperature(K) estimated by Joback Method.

5)Critical Pressure(bar)
Critical Pressure(bar) estimated by Joback Method.

6)Critical Volume(cm3)
Critical Volume(cm3) estimated by Joback Method.

7)Edmister Method omega
Omega estimated by Edmister Method.

8)Lee-Kesler Method omega
Omega estimated by Lee-Kesler Method.

9)Critical Constant
Critical Constant estimated by Jyoback Method.

10)Yen-Woods Method Density (g/cm3)
Density (g/cm3) estimated by Yen-Woods Method.

11)Reidel Method Vapor P (mmHg)
Vapor P (mmHg) estimated by Reidel Method.

12)Vetre Method Heat of Vaporization (at BP) (cal/mol)
Heat of Vaporization (at BP) (cal/mol) estimated by Vetre Method.

13)L-J Collision Diameter (Å)
Lennerd -Jones Collision Diameter (Å).

14)L-J Well Depth (J/mol)
