Component definition of PRO/II

This post was last edited by longkui1990 on 2011-10-27 at 12:11. In the PRO/II component definition, I want to enter K2O and P2O5, but these two substances are not available for entry. What should I do? ? ? Thank you all~~~
If not, it means there’s nothing in your material library. . We can only fix this material database. .
Reply to 1# amazing163: It can be synthesized through functional group synthesis. Then enter the physical property parameters.
Reply to 3# sui*nyi: Could you be more specific? ? ? Thank you
Reply 2# y303033490: Can the database be done the same way? ? ? It’s so amazing···· How do I do it? ?
For data that is not available, one has to conduct experiments or search through literature to obtain the relevant parameters; the group contribution method generally does not work well in such cases
Reply to 6# jc2006: The problem is that few people conduct experiments or such information can be found in literature, so there’s no way around it.
Both K2O and P2O5 are inorganic substances; PRO/II can’t figure this out. Do you handle solids? Do these two things change when they come into contact with water?
Reply to 8# cl6119: Wow, it’s clear you’re an expert. I want to define K2O and P2O5 as solids; they change when they come into contact with water, right?

But in practice, there should be a reaction – can the software still calculate correctly? If water is present in the system, it is recommended to use electrolytes based on thermodynamic principles; for the two combinations, components resulting from reactions with water should be used, namely potassium hydroxide and phosphoric acid.
