对氟苯甲脒杀菌剂的新型合成方式与表征

New preparation and characterization for fungicide of p-fluorobenzamidine

以对氟苯甲腈为原料进行了对氟苯甲脒合成反应的研究。采用新的合成方法使脒基化反应不需要通入干燥的氯化氢气体,对环境友好,无污染,并取得了较高的产率,操作方法简单易行。通过实验确定了最佳反应时间、最佳反应温度以及最佳物料之间的配比。

The synthesis of p-fluorobenzamidine with p-fluorobenzonttrile as raw material is studied. The new amidino-reaction can be carried out without dry HC1 and it has advantages of high Yields, no pollution to environment and simple operation. The optimal reaction times, reaction temperature and the proportions of materials are determined by the experiments
