| description | The invention belongs to the technical field of flotation reagent synthesis, and discloses a synthesis method of benzyl mercaptan bis-dialkyl dithiophosphate, which comprises the following steps of: synthesizing benzyl mercaptan dialkyl dithiophosphate from phosphorus pentasulfide and benzyl mercaptan as raw materials according to a certain molar ratio, and generating benzyl mercaptan bis-dialkyl dithiophosphate from the benzyl mercaptan dialkyl dithiophosphate under the action of an oxidizing agent. The method is reasonable in process design, high in yield and capable of avoiding environmental pollution.
本发明属于浮选药剂合成技术领域，公开了一种苄基硫醇双黑药合成方法，首先由原料五硫化二磷和苄基硫醇以一定的摩尔配比合成苄基硫醇黑药，苄基硫醇黑药在氧化剂作用下生成苄基硫醇双黑药；本发明工艺设计合理、产率高且避免环境污染。 |
