Determination of the solubility of NaOH in organic solvents in Aspen Plus
Thread Content
Help: In Aspen Plus, regarding the dissolution of NaOH in methanol, NaOH dissociates to yield hydroxide ions; however, since water is not present, the Elec Wizard cannot be used. How should I set it up to simulate the solubility of NaOH? Seeking advice from experts :(
Methanol reacts with sodium hydroxide to produce sodium methoxide and water. The entire solution system is still an electrolyte chemical equilibrium
So how should it be set in the ASPEN simulation? Because there is no water, hydroxide and sodium ions cannot be added using Elec Wizard :'(
First, add all the components involved in the system, including water... and then use thermodynamic methods – isn’t that enough to solve it?
But the component contains no water; won’t adding water have any effect?
Electrolytes are themselves aqueous solutions
Mm-hmm, I understand. Thank you{:1_90:}
