【摘要】 结合河北省桃园农药厂开发的百草枯新工艺(低温钠法),对百草枯生产过程中的环境风险进行评价。首先介绍了百草枯生产的工艺流程,然后系统分析了金属钠、吡啶、氯甲烷以及百草枯等危险物的性质及其危害性,并在上述分析的基础上,采用相应的评价模型对钠化釜及合成釜中吡啶可能造成的爆炸与扩散进行了评价。最后,就百草枯生产的环境风险提出了相应的对策和防范措施。更多还原

【Abstract】 The article assesses the potential environmentalrisk during the process of the production of Herbicide C₁₂H₁₄N₂Cl₂, which has been developed by TaoYuan Pesticide Plantin Hebei Province using a new technology. The article firstlyintroduces the production process of Herbicide C₁₂H₁₄N₂Cl₂,then analyzes the hazard to environment about mental Na,Pyridine, CH₃Cl and Herbicide C₁₂H₁₄N₂Cl₂, and assesses thepotential risk of pyridine using some qualitative assessmentmodule. In the end, the article puts forwards some measuresand suggestions for the production of Herbicide C₁₂H₁₄N₂Cl₂.更多还原
