1350218 Separating C 8 aromatics by adsorption UNIVERSAL OIL PRODUCTS CO 26 Aug 1971 [31 Aug 1970] 40067/71 Addition to 1236369 Heading C5E The process of the Specification 1,236,369 for the separation of C 8 aromatic isomers is improved by using as adsorbent a type X or type Y crystalline aluminosilicate containing Ba and K cations in a weight ratio of Ba : K of 1 : 1 to 100 : 1. Para-xylene is selectively retained by the adsorbent.
