• Does diatomic sulfur(S2) react as a free species?
  作者：Kosta Steliou、Paul Salama、Xiaoping Yu

  DOI：10.1021/ja00030a048

  日期：1992.2

  design and synthesis of stable 1,2-dithietane derivatives for the generation of diatomic sulfur (S 2 ) was undertaken. Computer-aided evaluation of enthalpic differences was used to direct the synthesis of target compounds and, although all of the compounds calculated to afford S 2 that were prepared did yield diatomic sulfur, an isolable 1,2-dithietane other than dithiatopazine failed to materialize

• Highly aromatic polyurea/urethane membranes and their use for separating aromatics from non-aromatics
  申请人：EXXON RESEARCH AND ENGINEERING COMPANY

  公开号：EP0312374A2

  公开（公告）日：1989-04-19

  Novel membranes, useful for the separation of aromatics from mixtures thereof with non-aromatics, in, for example, a naphtha feed stream, are characterized by possessing a urea index of at least about 20% but less than 100%, an aromatic carbon content of at least about 15 mole percent, a functional group density of at least about 10 per 1000 grams of polymer and a C = O/NH ratio of less than about 8.0. These highly aromatic polyurea/urethane membranes are symmetric, dense film membranes made from the corresponding polyurea/urethane copolymers by standard membrane casting techniques. The polyurea/urethane copolymers are preferably produced by reacting dihydroxy or polyhydroxy compounds, such as polyethers or polyesters having molecular weights in the range of about 500 to 5000 with aliphatic, alkylaromatic or aromatic diisocyanates or polyisocyanates and low molecular weight chain extenders, such as diamines, polyamines or amino alcohols. The membranes are useful for separating aromatics from non-aromatics in e.g., petroleum refining and chemical applications.
