ugropy | ||
====== | ||
|
||
ugropy is a ``Python`` library to obtain the UNIFAC’s subgroups from | ||
both the name or the SMILES representation of a molecule. If the name is | ||
given, the library uses the | ||
`PubChemPy <https://github.com/mcs07/PubChemPy>`__ library to obtain the | ||
SMILES representation from PubChem. In both cases, ugropy uses the | ||
`RDKit <https://github.com/rdkit/rdkit>`__ library to search the | ||
functional groups in the molecule. | ||
|
||
ugropy is in an early development stage, leaving issues of examples of | ||
molecules that ugropy fails solving the UNIFAC’s groups is very helpful. | ||
|
||
Models supported v1.0.0 | ||
======================= | ||
|
||
- Classic liquid-vapor UNIFAC | ||
- Predictive Soave-Redlich-Kwong (PSRK) | ||
- Joback | ||
|
||
Example of use | ||
============== | ||
|
||
You can check the full tutorial | ||
`here <https://ugropy.readthedocs.io/en/latest/tutorial/tutorial.html>`__. | ||
|
||
Get UNIFAC groups from the molecule’s name: | ||
|
||
.. code:: python | ||
from ugropy import Groups | ||
hexane = Groups("hexane") | ||
print(hexane.unifac_groups) | ||
print(hexane.psrk_groups) | ||
print(hexane.joback.groups) | ||
:: | ||
|
||
{'CH3': 2, 'CH2': 4} | ||
{'CH3': 2, 'CH2': 4} | ||
{'-CH3': 2, '-CH2-': 4} | ||
|
||
Get UNIFAC groups from molecule’s SMILES: | ||
|
||
.. code:: python | ||
propanol = Groups("CCCO", "smiles") | ||
print(propanol.unifac_groups) | ||
print(propanol.psrk_groups) | ||
print(propanol.joback.groups) | ||
:: | ||
|
||
{'CH3': 1, 'CH2': 2, 'OH': 1} | ||
{'CH3': 1, 'CH2': 2, 'OH': 1} | ||
{'-CH3': 1, '-CH2-': 2, '-OH (alcohol)': 1} | ||
|
||
Estimate properties with the Joback model! | ||
|
||
.. code:: python | ||
limonene = Groups("limonene") | ||
print(limonene.joback.groups) | ||
print(f"{limonene.joback.critical_temperature} K") | ||
print(f"{limonene.joback.vapor_pressure(176 + 273.15)} bar") | ||
:: | ||
|
||
{'-CH3': 2, '=CH2': 1, '=C<': 1, 'ring-CH2-': 3, 'ring>CH-': 1, 'ring=CH-': 1, 'ring=C<': 1} | ||
