PROCEDE DE SEPARATION DES DICHLOROTOLUENES ISOMERES PAR ADSORPTION SUR ZEOLITHES |
摘要 |
The process for the separation of isomeric dichlorotoluenes, comprising the steps of: (a) passing a mixture containing isomeric dichlorotoluenes over a zeolite of the ZSM5 type having the composition (expressed in molar ratios) of (0.9+0.2) M2/nO:Al2O3: (10-100) SiO2: z H2O in which M is at least one cation selected from H, an alkali metal, an alkaline earth metal or a tetraalkylammonium cation; n is the valency of M; and z is between 0 and 40: (b) separating the non-adsorbed dichlorotoluenes; (c) contacting the zeolite containing the adsorbed isomers with an eluent; and (d) separating the isomers from the eluent. |
