Abstract

1,273,911. Adsorbing organic materials from solution. OCTROOIEN MAATSCHAPPIJ ACTIVIT N.V. 4 June, 1970 [4 June, 1969], No. 26999/70. Heading C1C. Organic substances are removed from solution by sorption on a macroporous insoluble polymer of one or more vinyl- or divinylaromatic compounds, the polymer containing nitro, halogen or acetyl groups. The preferred polymer is a copolymer of styrene with 2-80% by weight divinylbenzene which contains nitro groups. Such a polymer is used to remove (a) phenol and sulphuric acid; benzoic acid; methanol; and propionic acid from water, (b) non-sugars from technical sugar solutions, and (c) organic material from drinking water. A similar polymer containing chloro groups instead of nitro groups is used to remove benzoic acid from n-heptane and toluene from water.
