邻苯二胺熔点103℃～104℃,沸点256℃～258℃,微溶于冷水,较多溶于热水,易溶于乙醇、乙醚和氯仿。与无机酸作用生成易溶于水的盐类,由硝基氯化苯衍生而制得。在农药生产中邻苯二胺主要用于生产苯并咪唑类杀菌剂,例如多菌灵、托布津、甲基硫菌灵等,而且含有苯并咪唑环化学结构的已经成为新型杀菌剂研制与开发的一个主要方向。其中,最具代表性的产品是广谱高效内吸式的多菌 O-phenylenediamine melting point of 103 ° C ~ 104 ° C, the boiling point of 256 ° C ~ 258 ° C, slightly soluble in cold water, more soluble in hot water, soluble in ethanol, ether and chloroform. With the role of inorganic acids to generate water-soluble salts derived from nitrochlorobenzene derived. In the production of pesticides o-phenylenediamine is mainly used for the production of benzimidazole fungicides, such as carbendazim, thiophanate, thiophanate-methyl and so on, and containing the chemical structure of benzimidazole ring has become a new fungicide development and One of the main directions of development. Among them, the most representative product is broad-spectrum efficient suction type of bacteria
