Nizar Matar

I hope that this information will help:

The main ingredient of "paraffin" wax is eicosane which is an alkane with the molecular formula C20H42. Eicosane is soluble in diethyl ether, petroleum ether, benzene; slightly soluble in chloroform; very soluble in acetone (Reference: Haynes, W.M. (ed.). CRC Handbook of Chemistry and Physics. 95th Edition. CRC Press LLC, Boca Raton: FL 2014-2015, p. 3-240 ).

My advice is to avoid chloroform & to use another solvent. There is no big problem when a solvent interact strongly with a solute but take care in carrying out dissolution in a fume cupboard.

SILAS DERENZO

can you use hexane? or iso-octane?

Rakesh Kumar Meghwanshi

Follow the method given by Nizar Matar.

he is absolutely right.

Dennis Schuetzle

Wax is also very soluble in carbon disulfide.
