[![PyPI
version](https://badge.fury.io/py/ugropy.svg)](https://badge.fury.io/py/ugropy)`ugropy` is a `Python` library to obtain subgroups from different thermodynamic
group contribution models using 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 subgroups of a model is very helpful.`ugropy` is tested for `Python` 3.10, 3.11 and 3.12 on Linux, Windows and Mac
OS.# Try ugropy now
You can try ugropy from its
[Binder](https://mybinder.org/v2/gh/ipqa-research/ugropy/main). Open the
binder.ipynb file to explore the basic features.# Models supported v2.0.7
- Classic liquid-vapor UNIFAC
- Predictive Soave-Redlich-Kwong (PSRK)
- Joback# Writers
`ugropy` allows you to convert the obtained functional groups or estimated
properties to the input format required by the following thermodynamic
libraries:- [Clapeyron.jl](https://github.com/ClapeyronThermo/Clapeyron.jl)
- [Thermo](https://github.com/CalebBell/thermo)# Example of use
You can check the full tutorial
[here](https://ipqa-research.github.io/ugropy/tutorial/tutorial.html).Get groups from the molecule's name:
```python
from ugropy import Groupshexane = Groups("hexane")
print(hexane.unifac.subgroups)
print(hexane.psrk.subgroups)
print(hexane.joback.subgroups)
```{'CH3': 2, 'CH2': 4}
{'CH3': 2, 'CH2': 4}
{'-CH3': 2, '-CH2-': 4}Get groups from molecule's SMILES:
```python
propanol = Groups("CCCO", "smiles")print(propanol.unifac.subgroups)
print(propanol.psrk.subgroups)
print(propanol.joback.subgroups)
```{'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!
```python
limonene = Groups("limonene")print(limonene.joback.subgroups)
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}
