    • A process for the manufacture of 2,3,5-trimethylhydroquinone diacylate comprising reacting ketoisophorone with an acylating agent in the presence of a NH- or CH-acidic catalyst, particularly certain bis(perfluorinated hydrocarbyl sulphonyl) imides and metal salts thereof and, respectively, certain tris(perfluoroalkanesulphonyl or pentafluorobenzenesulphonyl) methanes and metal salts thereof. The acylating agent is particularly an acid anhydride, an acyl halide or an enol ester. The so-obtained 2,3,5-trimethylhydroquinone diacylate can be converted into (all-rac)-α-tocopherol by transesterification to yield 2,3,5-trimethylhydroquinone and reaction of the latter with isophytol. (all-rac)-α-Tocopherol itself is the most active member of the vitamin E group.
    • 包括制备2,3,5-三甲基氢醌二酸酯的方法,其包括在NH-或CH-酸性催化剂,特别是某些双(全氟化烃基磺酰基)酰亚胺及其金属盐的存在下使酮异二氢酮与酰化剂反应,和 ,某些三(全氟烷基磺酰基或五氟苯磺酰基)甲烷及其金属盐。 酰化剂特别是酸酐,酰基卤或烯醇酯。 如此获得的2,3,5-三甲基氢醌二酸酯可以通过酯交换反应转化成(全脱色)-α-生育酚,得到2,3,5-三甲基氢醌并将其与异麦芽糖醇反应。 (全消旋)-al-生育酚本身是维生素E组中最活跃的成员。

    • A sensing system for sensing conditions or characteristics associated with a process or thing. The sensing system includes one or more energy converters and a sensor, which are coupled to the process or thing. A node is coupled to the sensor and the energy-converter, and the node is powered by output from the energy converter. In a more specific embodiment, the node includes a controller that implements one or more routines for selectively powering a wireless transmitter of the node based on a predetermined condition. The predetermined condition may specify that sensor output values are within a predetermined range or are below or above a predetermined threshold. Alternatively, the predetermined condition may specify that electrical energy output from the energy converter is below a predetermined threshold. A remote computer may be wirelessly connected to node and may include software and/or hardware that is adapted to process information output by the sensor and relayed to the computer via the node.
    • 用于感测与过程或事物相关的条件或特性的感测系统。 感测系统包括一个或多个能量转换器和耦合到过程或物体的传感器。 节点耦合到传感器和能量转换器,并且节点由能量转换器的输出供电。 在更具体的实施例中,节点包括实现一个或多个例程的控制器,用于基于预定条件选择性地为节点的无线发射机供电。 预定条件可以指定传感器输出值在预定范围内或低于或高于预定阈值。 或者,预定条件可以指定从能量转换器输出的电能低于预定阈值。 远程计算机可以无线地连接到节点,并且可以包括适于处理由传感器输出并经由节点中继到计算机的信息的软件和/或硬件。
