Preparation of Sulprofos: At first, add organic solvent and phosphorus pentasulfide into reactor. Then add a fixed quantity of catalyst and 4-methylthiophenol sodiumate. Next, add a fixed quantity of anhydrous alcohol and bromine propane mixture. Heat the mixture to 70 °C. After the reaction, via a series of extraction, washing by alkali and water, drying by anhydrous sodium sulfate and vacuum distillation you can get the desired product.
