Abstract
Abstract 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 feedstreams, and from vapor and gas feedstreams by absorption.
