摘要:
Processes for preparing vinyl nortricyclane (I) and its hydrogenated derivative, ethyl nortricyclane (II) are disclosed. The nortricyclane (II) can be used as a high energy fuel or a fuel diluent. Process involves codimerization of norbornadiene and ethylene in the presence of a homogeneous catalytic system of cobaltic or cobaltous acetylacetonate, 1,2-bisdiphenylphosphino ethane and an alkyl aluminum chloride to yield the vinyl nortricyclane (I). The latter can be hydrogenated to ethylnortricyclane.
摘要:
A sulfated calcined solid catalyst which comprises (1) oxide or hydroxide of Group III or Group IV, e.g. zirconium, metal, (2) oxide or hydroxide of Group V, Group VI or Group VII, e.g. manganese or molybdenum, metal and (3) oxide or hydroxide of Group VIII, e.g. iron, or cobalt metal, is used to isomerize normal alkanes having 4 to 7 carbon atoms per molecule in the liquid phase to obtain high octane number blending components for motor fuel and/or valuable chemical and fuel intermediates.
摘要:
Isomerization of a liquid, saturated endo-endo norbornadiene hexacyclic dimer involves the use of a catalytic amount of acidic alumina or a montmorillonite. The resulting isomeric product is solid, at ambient temperature, and can be used as a missile fuel.
摘要:
Norbornadiene and acrylonitrile are catalytically codimerized in the presence of a three-component homogeneous catalytic system consisting of nickel acetylacetonate, triphenylphosphine and an alkyl aluminum chloride. The codimer can be used as a precursor for missile fuel.
摘要:
Norbornadiene and an acrylic acid ester, e.g., methyl acrylate, are catalytically codimerized in the presence of a two-component homogeneous catalytic system consisting of nickel acetylacetonate and an alkyl aluminum chloride. The resulting codimer can be used as a precursor for a missile fuel. The ester portion of the acrylic acid ester is the radical RCH.sub.2 O-- wherein the R is an H or an alkyl containing up to 10 carbon atoms.

摘要:
Acyclic hydrocarbons having 4 to 7 carbon atoms per molecule are isomerized in the liquid phase by contact with a solid superacid catalyst comprising sulfated oxide or hydroxide of a metal selected from the group consisting of Group III and Group IV metals, to obtain high octane number blending components for motor fuel and/or valuable chemical and fuel intermediates.
摘要:
The endo-endo olefinic hexacyclic dimer of 2,5-norbornadiene is isomerized using an acidic alumina catalyst. The isomerization temperatures ranges from between about an ambient temperature to about 300.degree. C. The isomerized product, after hydrogenation, can be used as a high density missile fuel.
摘要:
Norbornadiene [bicyclo(2.2.1)heptadiene-2,5] is dimerized to the exo-exo stereoisomer of the hexacyclic dimer of norbornadiene at both an excellent selectivity and conversion using an effective amount of a three component catalytic system of diethylaluminum chloride, ferric or ferrous or cobaltic or cobaltous acetylacetonate and bis(1,2-diphenylphosphino)ethane. The reaction rate is rapid. After hydrogenation the exo-exo hexacyclic dimer can be used as a component of high energy fuel for either jet or rocket propulsion.
