I put Q3C class 3 solvents and several green solvents in this program. If I want to dissolve something, I just input traget HSP and push Search button. Program will search shortest HSP distance ratio for each combination.

ESTASOL™ Oxygenated Solvents

Eco-friendly solvent


If you are lucky enough your browser support JAVA and proper setting of JAVA option, you will see the window like above. If you can not see this window, please check browser's JAVA option or try other browser. Eventhough you fail. Give up this IAVA verson.

HSP Distance

HSP distance(Ra)={4*(dD1-dD2)2 + (dP1-dP2)2 +(dH1-dH2)2 }0.5

The Procedure is very simple.

Solvent A - Solvent B change ratio with 1%. Calculate 101 (0%A-100%B to 100%A-0%B) HSP distance and get shortest HSP distance.

HSP of Solvents Mixture

[dDm, dPm, dHm]=[(a*dD1+b*dD2), (a*dP1+b*dP2),(a*dH1+b*dH2)]/(a+b)

Ratio is Volume.

Please refer to original article in HSP application note.
