• Sustained release dispenser comprising two or more sex pheromone substances and a pest control method
  申请人：Shin-Etsu Chemical Co., Ltd.

  公开号：EP1459626A1

  公开（公告）日：2004-09-22

  Provided are a sustained release dispenser which can control the release of sex pheromone simultaneously toward two or more species of insect pests and can also release the sex pheromone in response to the generation period of insect pest and the pest control method toward two or more insect pests. Provided specifically is a sex pheromone sustained release dispenser comprising two or more sex pheromone substances, each substance being aliphatic derivative having 10 to 20 carbons, and first and second chambers wherein some or all of the sex pheromone substance having a smallest carbon number excluding a carbon number in a functional group is contained in a first polymer chamber and the remainder is contained in a second polymer chamber. Provided also is a pest control method for using the sex pheromone sustained release dispenser.

  本发明提供了一种性信息素持续释放分配器，该分配器可控制同时向两种或两种以上害虫释放性信息素，还可根据害虫的生成期释放性信息素，以及针对两种或两种以上害虫的害虫控制方法。特别提供了一种性信息素持续释放分配器，包括两种或两种以上的性信息素物质，每种物质都是具有 10 至 20 个碳原子的脂肪族衍生物，以及第一和第二室，其中具有最小碳原子数（不包括官能团中的碳原子数）的性信息素物质的一部分或全部包含在第一聚合物室中，其余部分包含在第二聚合物室中。还提供了一种使用性信息素持续释放分配器的害虫控制方法。

• Photodegradation of Hydrophobic Pyridineketoximes in Toluene and Heptane
  作者：Karolina Wieszczycka、Joanna Zembrzuska

  DOI：10.1111/php.12453

  日期：2015.7

  AbstractThe goal of the research was to study the reactivity of the hydrophobic 2‐ and 3‐pyridineketoximes under exposure to UV‐VIS light. The photodegradation was conducted in both toluene and heptane for 10 h under atmosphere of argon. Ten‐hour irradiation experiments demonstrated that the pyridineketoximes underwent the facile E‐Z photoisomerization, photo‐Beckmann rearrangement, and to a lesser extent, the photosubstitution to the pyridine ring. From LC‐MS and NMR analysis of the irradiated solutions, it was found that the photosubstitution proceeded to give the corresponding 6‐substituted 2‐ or 3‐pyridylketoxime via the replacement of the ring hydrogen by the benzyl or heptyl group. The photo‐Beckmann rearrangement led to the formation of the corresponding amides, but also other products formed in the photo‐decomposition reaction.
