How calculate ularasonic parameter redlichkister equation?

Answer 1

You can also use the softs: OriginPro or Kaleidagraph, it give you parameters with accuracy,...

You plot the curve of the property (Y) versus the molar fraction (x): Y=f(x) and You write for example: Y=P4*x+P5*(1-x)+x*(1-x)*(P0+P1*x+P2*x^2+P3*x^3) with P4 and P5 are the property Y of the pure component 1 and 2.

In addition, think about the reduced Redlich-Kister functions, (see our papers), you will be find very interesting additional informations related to existing clusters, molecular interactions,... It's a very new concept, it needs confirmation and complements with NMR and spectroscopic techniques
