| titleOfInvention | Preparation method of malathion |
| abstract | The invention relates to a preparation method of malathion. The preparation method comprises the following steps of firstly, mixing an organic solvent and a wet product of malathion, distilling and dehydrating to prepare malathion; secondly, distilling and dehydrating through spray heating or membrane evaporator heating by taking the solvent as a carrier to realize the continuous operation of a dehydration process as well as wet-process smashing, blending and packaging processes; and thirdly, simultaneously finishing the operation of complexing maneb and zinc in the organic solvent and the process of dehydrating for crystal transformation. Due to the implementation of the third step, the decomposition of a product is reduced, the harmful impurity and dust pollution is reduced, and a fire accident generated in a product drying process is avoided. |
