ABSTRACT OF THE DISCLOSURE Novel solid salt compositions are described containing, for example, tetraaryl- and triarylaralkyl- phosphonium and arsonium cations and tetraaryl- and tetraaryloxy-boranates and aluminates and polyanionic metal oxide surfaces, for example, as anions. The salts are useful for extracting aromatics and olefins from paraffinic hydrocarbon and aqueous liquid feed- streams, and from vapor and gas feedstreams by absorp- tion.
