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： 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。
