How could the radius of Hansen solubility parameter determined??
I could understand how to determine three-Hansen parameter
(polar component, dispersion component, hydrogen bonding component), but I don't understand how to determine the radius of Hansen sphere.
So, would anyone tell me how to caluculate and determine the radius of Hansen spere?, Please !!
Answer:
Hansen Solubility Parameters were developed by Charles Hansen as a way of predicting if one material will dissolve in another and form a solution. They are based on the idea that like dissolves like where one molecule is defined as being 'like' another if it bonds to itself in a similar way.
Specifically, each molecule is given three Hansen parameters, each generally measured in :
The energy from dispersion bonds between molecules
The energy from polar bonds between molecules
The energy from hydrogen bonds between molecules
These three parameters can be treated as co-ordinates for a point in three dimensions. The nearer two molecules are in this three dimensional space, the more likely they are to dissolve into each other.
