权利人:SPIELVOGEL BERNARD; COOK KEVIN S; SEMEQUIP INC
摘要:The invention provides new methods for the synthesis of isotopically enriched metal borohydrides, metal tetrahydroundecaborate salts, and decaborane from isotopically enriched 10 B-boric acid or 11 B-boric acid. The invention is particularly useful for synthesis of isotopically enriched sodium or lithium borohydride, MB 11 H 14 (where M is Li, Na, K, or alkylammonium), and decaborane.

权利人:GOODYEAR TIRE & RUBBER
摘要:The subject invention relates to a technique for synthesizing rubbery copolymers of styrene and isoprene. These rubbery copolymers exhibit an excellent combination of properties for utilization in tire tread rubber compounds. By utilizing these styrene-isoprene rubbers in tire treads, tires having improved wet skid resistance can be built without sacrificing rolling resistance or tread wear characteristics. This invention more specifically discloses a process for the synthesis of styrene-isoprene rubbers which comprises copolymerizing isoprene monomer and styrene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) an alkyl tetrahydrofurfuryl ether modifier, wherein the molar ratio of the modifier to the lithitium initiator is within the range of 2:1 to 40:1. The subject invention further discloses a process for the synthesis of styrene-isoprene rubbers which comprises copolymerizing isoprene monomer and styrene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) 2,2-ditetrahydrofurylpropane as a modifier, wherein the molar ratio of the modifier to the lithium initiator is within the range of 1:1 to 40:1.

摘要:The present invention relates to a process for the synthesis of haloalkylferrocenes, comprising a first stage of reaction, in the presence of AlCl 3 as catalyst and in organic solvent medium, of a carboxylic acid halide or anhydride with ferrocene or an alkylferrocene. n After this stage, without prior isolation of the intermediate compound, a metal hydride is added to the reaction mixture. n The haloalkylferrocenes are particularly useful as intermediates in the synthesis of combustion catalysts for propellants.
