    Abstract: Disclosed is a method for processing naphtha, according to which a) naphtha or a stream generated from naphtha in a preprocessing step is divided into a stream A that is stripped of aromatics and a stream B which is enriched with aromatics in a membrane unit, the aromatics concentration in stream A ranging from 2 to 12 percent by weight (step a); b) partial stream A is directed at least in part into a steam cracker (step b); c) partial stream B is directed at least in part into a unit in which said stream B is divided into a stream C or several streams C' C'', C''',..., which has/have a lower aromatics content than stream B, and a stream D or several streams D', D'', D''',..., which has/have a higher aromatics content than stream B, by means of a thermal process (step c); d) stream C or at least one of the streams C', C'', C''' is delivered as a whole or in part to the feed for the steam cracker or directly to the steam cracker (step d).

    Abstract: Process for the work-up of naphtha, wherein a) naphtha or a stream produced from naphtha in a pretreatment step is separated in a membrane unit into a stream A which is depleted in aromatics and a stream B which is enriched in aromatics, with the aromatics concentration in stream A being from 2 to 12% by weight (step a), b) at least part of the substream A is fed to a steam cracker (step b), c) at least part of the substream B is fed to a unit in which it is separated by means of a thermal process into a stream C which has a lower aromatics content than stream B or a plurality of streams C', C'', C''' . . . which each have lower aromatics contents than stream B and a stream D which has a higher aromatics content than stream B or a plurality of streams D', D'', D''' . . . which each have higher aromatics contents than stream B (step c), and d) the stream C or at least one of the streams C', C'', C''', in each case in part or in its entirety, is added to the feed to the steam cracker or fed into the steam cracker itself (step d).

    Abstract: A crosslinkable copolyimide consisting mainly of repeating units derived from dianhydrides of given formula and containing primary amine groups, where these are in the ortho, meta, or para positions to the ether function is new. A crosslinkable copolyimide consisting mainly of repeating units derived from dianhydides of formula:(A), diamines of formula (I), diamines of formula (II): where the amino groups are in the ortho, meta, or para position, and 1 or 2 aromatic nucleus H atoms can be substituted by 1-4X alkyl, and diamines of formula (III):and containing primary amine groups, where these are in the ortho, meta, or para positions to the ether function. R1 = COOH or SO3H. Independent claims are included for: (1) membranes obtained from the crosslinked copolyimides; (2) chromatography columns containing the crosslinked copolyimides as the stationary phase; (3) a method of separating alcohols from mixtures with organic compounds of lower polarity than the alcohol, for separation of ammonia or amines from mixtures with organic compounds of lower polarity than ammonia, and for separation of water, ammonia, H2S, or organic compounds from mixtures with nitrogen or air, separation of olefins or dienes from mixtures with hydrocarbons of higher degree of saturation than the olefin or diene, e.g. separation of olefin/alkane using the membranes described or chromatography columns; (4) an olefin/alkane mixture enriched in olefin compared with the starting mixture by means of a membrane as described, and an alkane enriched stream separated, at a pressure on the membrane feed side higher than 6 bar.
