天津市瑞凯科技发展有限公司日前推出了异丁腈用催化剂技术。采用气相法连续生产异丁腈的新型催化反应工艺与技术制得的异丁腈纯度高,可直接用于合成二嗪磷。该技术突破了传统工艺难关,大大降低了二嗪磷的生产成本。已在千吨级规模工业装置上放大成功,并获得了国家发明专利。二嗪磷又称二嗪农、地亚农,是一种广谱、高效有机磷杀虫杀螨剂。二嗪磷毒性较低,具有高效、低毒、低残留等特点。它对鳞翅目、同翅目等多种害虫有较好的防治效果,
Tianjin Ruikai Technology Development Co., Ltd. has introduced a catalyst technology for isobutyronitrile. The isobutyronitrile obtained by the novel catalytic reaction process and technology of continuous production of isobutyronitrile by gas phase has high purity and can be directly used for the synthesis of diazinon. The technology breaks through the difficulties of traditional process and greatly reduces the production cost of diazinon. It has been successfully enlarged on a kiloton scale industrial plant and won the national invention patent. Diazinon, also known as diazinon, to Asia farmers, is a broad-spectrum, high efficiency organophosphate insecticide miticide. Diazinon low toxicity, with high efficiency, low toxicity, low residue and so on. It Lepidoptera, Homoptera, and other pests have a better control effect,
