摘要:气相核磁共振动力学技术首次用于精确测量一些双分子二级环加成反应的速率常数.为了测试该技术在二级反应研究中的潜在用途,在 240-340 度的温度范围内确定了三氟氯乙烯 (Ctfe) 和四氟乙烯 (Tfe) 环二聚反应的速率常数和活化参数c,使用商业高温核磁共振探头.结果与公布的数据非常吻合,然后将该技术应用于 1,1-二氟丙二烯与 1,3-丁二烯的反应,其结果表明,当试剂数量很少且同时存在多个竞争过程时,将气相 NMR 用于反应动力学特别有价值.在该反应中观测到的主要过程是区域选择性 [2+2] 和 [2+4] 环加成,其速率和活化参数已确定 [k2 = 9.3 X 10(6) Exp(-20.1 Kcal X Mol(-1)/ Rt) L/mol(-1) Xs(-1) 和 K3 = 1.2 X 10(6) Exp(-18.4 Kcal X Mol(-1)/rt) L/mol(-1) Xs(-)(1

标题 :Method for the synthesis of product molecules
发明人：WEISS HORST; GERBER GUSTAV; NUERNBERGER PATRICK HENNING; WOLPERT DANIEL STEPHAN
权利人:BASF AG
摘要:The invention relates to a method for the synthesis of product molecules, wherein ultrashort laser pulses shaped with the aid of a pulse shaper are generated and a gas which contains educt molecules is fed onto a surface, on which the educt molecules are at least partially adsorbed, the shaped ultrashort laser pulses being directed onto the surface in order to control a reaction process for synthesis of the product molecules from educts adsorbed on the surface.

标题 :Synthesis of polyphosphazenes with sulfonimide side groups
发明人：ALLCOCK HARRY R; HOFMANN MICHAEL A; AMBLER CATHERINE M; MAHER ANDREW E; WOOD RICHARD M; WELNA DANIEL T
权利人:PENN STATE RES FOUND
摘要:The invention relates to sulfonimide bearing phenolic compounds and the use of those compounds to produce polyphosphazenes functionalized by one or more of those compounds alone, or in combination with cosubstituents. The invention also relates to blends of sulfonimide functionalized phosphazene polymers with other polymers, membranes formed of the functionalized polymers, and the use of those membranes in devices such as fuel cells.
