Purification of cyclohexane

摘要

Solvents which may be used as mediums for the polymerization of olefinic hydrocarbons to form polymers useful as membranes in a gas separation process require purification to remove any impurities which will effect the aforesaid polymerization. Purification of these solvents such as cyclohexane may be effected by treating the solvent with titanium tetrachloride, contacting the solution with an adsorbent such as silica gel and thereafter distilling the solvent in the presence of a purification agent such as an alkaline metal aluminum hydride or borohydride.
