    • Provided is an annular sustained release preparation to be used by opening a center portion thereof, the preparation having a strength enough to avoid cleaving at a welded end portion. More specifically, provided is an annular sustained release preparation comprising at least two polymer tubes having both ends sealed and integrated by pressure-welding or at least one polymer tube and at least one polymer rod having both ends sealed and integrated by pressure-welding; and a sex pheromone liquid contained by at least one of the tubes or the tube; wherein an annular space can be formed by pulling the tubes or the tube and the rod apart from each other at a center portion therebetween, the central portion not having been pressure-welded; and an angle formed between a line connecting respective centers of diameters of the tubes welded to each other or the tube and the rod welded to each other and the pressure application direction is from 0 to 45°.
    • 提供一种通过打开其中心部分而使用的环形缓释制剂,该制剂具有足以避免在焊接端部处分裂的强度。 更具体地,提供了一种环形缓释制剂,其包括至少两个聚合物管,其两端通过压焊或至少一个聚合物管密封并整合,并且至少一个聚合物棒的两端通过压焊密封和集成; 和由至少一个管或管包含的性信息素液体; 其中可以通过在它们之间的中心部分处拉动所述管或所述管和所述杆彼此分离而形成环形空间,所述中心部分未被压焊; 并且在彼此焊接的管或连接管的直径的管线与彼此焊接的杆和压力施加方向之间形成的角度为0至45°。

    • An efficient method is proposed for the synthesis of an unsaturated alcohol of the general formula R--CH.dbd.CH(CH.sub.2).sub.n+1 OH, in which R is a hydrogen atom or a monovalent hydrocarbon group having 1 to 10 carbon atoms and the subscript n is an integer in the range from 3 to 10, in which an acetate of the formula R--CH.dbd.CHCH.sub.2 OCOCH.sub.3 is subjected to a coupling reaction with a Grignard reagent of the formula X.sup.1 Mg(CH.sub.2).sub.n OMgX.sup.2, in which X.sup.1 and X.sup.2 are each a halogen atom, and then the reaction product is hydrolyzed. When the reaction product of the coupling reaction is reacted with acetic anhydride instead of hydrolysis, the corresponding acetate can readily be obtained. These unsaturated alcohols and acetates form a class of important biologically active compounds or intermediates thereof including sex pheromone compounds of insects.
    • 提出了合成通式为R-CH = CH(CH 2)n + 1OH的不饱和醇的有效方法,其中R为氢原子或具有1-10个碳原子的一价烃基,下标n 是3至10的整数,其中式R-CH = CHCH2OCOCH3的乙酸酯与式X1Mg(CH2)nOMgX2的格氏试剂进行偶联反应,其中X1和X2各自为 卤素原子,然后反应产物水解。 当偶联反应的反应产物与乙酸酐反应而不是水解时,可以容易地获得相应的乙酸酯。 这些不饱和醇和乙酸酯形成一类重要的生物活性化合物或其中间体,包括昆虫的性信息素化合物。
