    摘要： A process for selecting a perfluorocarbon compound from those having about 9 to 12 carbon atoms for preparing synthetic blood compositions. The process involves determining the critical solution temperature of the perfluorocarbon compound in a solvent such as n-hexane. The perfluorocarbon compound is accepted as suitable for preparing a synthetic blood composition if its critical solution temperature falls below a selected temperature set by the number of carbon atoms in the perfluorocarbon compound.

    摘要： A process for the separation and recovery of substantially pure ammonia from its admixture with gases, particularly with gases containing carbon dioxide and gases obtained from the catalytic ammoxidation of hydrocarbons to the corresponding nitriles, by scrubbing the ammonia containing gases with an aqueous solution containing a mixture of salts having different cations and the anions of one or more inorganic acids capable of absorbing and liberating ammonia; e.g., mixtures of different alkali metal salts of phosphoric, telluric, boric, vanadic, chromic, selenic, germanic, silicic and similar acids. Preferably the anion component will be at least one of phosphoric, chromic, or boric acids.

    摘要： In a cyanoalkylation process involving the reaction of a cyanoalkene compound such as acrylonitrile with a compound containing a labile hydrogen such as ethylene glycol, to form a cyanoalkylated product such as 3,3'-ethylenedioxy-bis(propionitrile), the reaction is carried out in the presence of cyanoalkylated product in addition to the cyanoalkylated product which is formed in situ by reaction of the reactants. High yields of cyanoalkylated product and low formation of by-products are obtained.

    摘要： The removal of color bodies from an olefinic or saturated endo-endo hexacyclic homodimer of norbornadiene or mixtures thereof is accomplished by the use of a serpentine clay. Also acid bentonite clay or a montmorillonite clay can be used to remove the color bodies from the saturated dimer. The saturated dimer has a high density and a high heat of combustion making it useful as a missile fuel. Removal of the color bodies avoids possible catalyst poisoning in the hydrogenation of the olefinic to the saturated dimer. Also removal of the color bodies from the saturated dimer eliminates the possible problem of a material precipitating out on engine turbine blades and causing maintenance or operational problems.

    摘要翻译： 通过使用蛇纹石粘土来实现从降冰片二烯的烯属或饱和内六角六环同系二聚体或其混合物中去除着色体。 酸性膨润土或蒙脱石粘土也可用于从饱和二聚体中除去颜色体。 饱和二聚体具有高密度和高的燃烧热，使其可用作导弹燃料。 去除颜色体可以避免在烯烃氢化成饱和二聚体时催化剂中毒。 从饱和二聚体中去除颜色体也消除了在发动机涡轮叶片上析出物质并导致维护或操作问题的可能问题。
