How to separate sodium bicarbonate from heavy alcohols (mixtures of ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, water, etc.)?
Thread Content
I would like to ask how to separate sodium bicarbonate from heavy alcohols (mixtures of ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, water, etc.) Thank you
This topic is great; I want to learn *. I have another question: how is sodium bicarbonate produced? Did you add alkali? Why remove it? It doesn’t affect light transmission, does it? Did it have an impact?
It should be the residual liquid from the EOEG device
A film-evaporator can be used to concentrate the solution, which is saline
Sodium bicarbonate is insoluble in alcohol, right? First dehydrate, then crystallize at low temperature, and finally recover the organic substances under high negative pressure
