Dear Sirs,

Please, I need information about de solubility (grams/Liter, %weight or %volume) of sodium or potassium hydroxide (caustic or potassium soda) in monoethylene glycol (MEG). Where I can to find references about this information?

Many Thanks.

Many Thanks, Breizh.


I reviewed general information about this theme, the solubility the Na(OH) vary in the 3 to 5% in the ethylene glycol (MEG) for the preparation of refrigerants. I need a reference confiable, also if there is a K(OH) information it is wellcome.


In our laboratory we obtained only the solubility the NaOH at 1% in MEG, but more concentration is not possible we have precipitation. Maybe there are a "recipe" for the preparation.


I need this information for to do test of injection in reflux in our crude oil distilation tower.
