ABSTRACT:
A method for separating wax from wax containing paper. The method involves immersing the wax containing paper in a heated alkane solvent, preferably n-hexane, to dissolve the wax contained in the paper into the solvent. The dissolved wax and solvent forms a miscella which is later separated from the paper. Any residual solvent absorbed in the paper is removed therefrom. The method also involves retrieving the wax from the miscella.
