Reaction Conditions:
with disulfur dichloride;sodium phosphate at 20; for 2 h;Reagent/catalyst;Temperature;
Steps:
1-5; 1-3 Example 1
In a 1L reactor, add 45.37 g of morpholine and 81.51 g of anhydrous trisodium phosphate.500g120 solvent oil, control the temperature to 20 , turn on the stirring,Slowly add 31.97 g of sulfur monochloride to the system. After about 2 hours, the drop of sulfur monochloride is completed.While maintaining the temperature, stirring was continued for about 2.5 h, and the reaction was completed. Add 200g of water for washing,Stir for 15 minutes, suction filter and then dry the filter cake to obtain 53.57 g of white needle-like crystals.Yield was 95.85%. Melting point was 123-127 ° C as measured by DSC.The purity was 99.61% measured by high performance liquid chromatography.
