标题 :Synthesis of haloindenes
发明人：WNUK STANISLAW F; HOWLADER MD ABU HASAN
权利人:WNUK STANISLAW F; HOWLADER MD ABU HASAN; THE FLORIDA INTERNATIONAL UNIV BOARD OF TRUSTEES
摘要:The subject invention provides an expedited synthesis of 5, 6, and 7-iodoindenes from the corresponding aminoindan-1-ones in more than 70% yield, employing readily available precursors and reagents. A three-step sequence involves diazotization-iodination of aminoindan-1-one followed by reduction and dehydration. The method has a general character and can be extended for the preparation of various 4-, 5-, 6- or 7-haloindenes using different halogen sources for diazotization-halogenation reaction.

权利人:UNIV RICE WILLIAM M; BETABATT INC
摘要:The present invention relates generally to synthesis of radioactive material, such as a tritiated polymer, and an apparatus for generating electrical current from the nuclear decay process of a radioactive material. In one embodiment, the invention relates to an energy cell (e.g., a battery) for generating electrical current derived from particle emissions occurring within a radioactive material such as a tritiated polymer) on pore walls of a porous semiconductor. The radioactive material may be introduced into the energy cell by a wetting process.

标题 :Synthesis and polymerization of vinyl triazolium ionic liquids
发明人：LUEBKE DAVID; NULWALA HUNAID; MATYJASZEWSKI KRZYSZTOF; ADZIMA BRIAN
权利人:US ENERGY; THE US DEPARTMENT OF ENERGY
摘要:Herein, we describe polymerized ionic liquids, demonstrate the synthesis of polymerized ionic liquids, and demonstrate the polymerization of triazolium monomers. One embodiment shows the polymeriazation of the triazolium monomers with bis(trifluoromethanesulfonyl)imide anions. In another embodiment we show the feasibility of copolymerizing with commodity monomers such as styrene using free radical polymerization techniques.

标题:Alkyl tetrahydrofurfuryl ethers as anionic polymerization modifier in the synthesis of rubbery polymer
发明人：HSU WEN-LIANG; HALASA ADEL F; MATRANA BARRY A
权利人:GOODYEAR TIRE & RUBBER
摘要:It has been unexpectedly discovered that various compounds, such as alkyl tetrahydrofurfuryl ethers, can be used to modify anionic polymerizations of conjugated diene monomers. These modifiers can be used to polymerize isoprene monomer into high 3,4-polyisoprene at excellent polymerization rates. This is in contrast to the modifiers such as tetramethylethylene diamine which are typically used to modify such polymerizations. This invention more specifically discloses a process for the synthesis of 3,4-polyisoprene which comprises polymerizing isoprene monomer in an organic solvent in the presence of a catalyst system which is comprised of (a) a lithium initiator and (b) a modifier which is an alkyltetrahydrofurfuryl ether selected from the group consisting of ethyltetrahydrofurfuryl ether, propyltetrahydrofurfuryl ether, and butyltetrahydrofurfuryl ether. In the practice of this invention, the utilization of ethyltetrahydrofurfuryl ether is highly preferred since its use results in faster polymerization rates and higher vinyl contents in the resultant polymer.

In the practice of this invention, the utilization of alkyltetrahydrofurfuryl ethers having alkyl groups which contain from 6 to 10 carbon atoms, such as hexyltetrahydrofurfuryl ether, is highly preferred since their use does not results in the creation of odor problems.
