📜辛二酸置于氯化亚砜体系中,化学反应生成1,8-二辛酰氯 参考文献:一类以1,3,5-三羟基苯单元为核心的新型星形胆甾型液晶 标题:一类以1,3,5-三羟基苯单元为核心的新型星形胆甾型液晶 摘要:摘要 以1,3,5-三羟基苯单元为核心,ω-胆甾醇烷基二酸单酯为介晶臂,设计合成了一类新的星形胆甾型液晶.它们的化学结构已通过元素分析,Ft-Ir 和 1H NMR 确认.通过差示扫描量热法,热重分析,偏光显微镜和 X 射线衍射测量研究了介晶性质和热稳定性.实验结果表明介晶臂结构强烈影响相行为.图 4A 没有显示任何液晶性,而 4B,4C 和 4D 显示可逆胆甾相转变.随着星形化合物的中间烷基链加长(从 N = 2 到 N = 8),它们的熔点降低,但介晶温度范围增加.焦点圆锥纹理,在液晶状态下可以观测到胆甾相之一.

专利号:US-5082958-A 优先权日:1990-01-22 标题 :Novel synthesis of difunctional halo organo noncarbon group iv main group element amides 发明人:WRIGHT ANTONY P; VARAPRATH PADMAKUMARI J 权利人:DOW CORNING 摘要:Difunctional halo silicon amide compounds are prepared by cleaving the nitrogen-silicon bond in a nitrogen-silicon heterocycle with a reactive halide. The reaction is straight forward with no intermediates or byproducts. The halo functionality is capable of capping any SiOH group. When the other functionality is an acrylamide, the capped entity may be polymerized or crosslinked by free radical initiators of the acrylamide functionality thereby producing useful products such as paper release coatings and photoresists.
