Hello Friends,
A quick question, can I use RO to separate propylene glycol from water? I am confused because it has low molecular weight and also not sure about the polarity. Can any body help me?
Thank you so much.

Liquid-liquid extraction (solvent extraction) is better using suitable solvent.
It would be better to use Membrane Distillation (MD) Process, where the separation by MD process is based on the relative volatility of various components in the feed solution ..
Theoretically it must work. You may correct if I am wrong.
The pore size of RO membrane is equal to molecular size of H2O. Here the propylene glycol is much larger than water with 3 Carbon, 2 Oxygen and 8 Hydrogen atoms. Hence, propylene glycol and water mixture under RO will result in splitting of water from the mixture based on pore size of RO membrane.
Kindly correct me if I am wrong since I have not done this experiment. It is a theoretical perspective based on working fundamental of RO process.
