Reaction Conditions:

with potassium thioacyanate at 80 - 220; under 0 - 2.25023 Torr; for 1.25 h;Inert atmosphere;Temperature;Reagent/catalyst;

Steps:

1 Example 1
89 g of potassium thiocyanate was added to the closed reactor,The reactor was heated to 180 ° C under a vacuum of -0.099 MPa,Potassium thiocyanate is melted and the agitator is started and stirred mechanically,The temperature of the reactor was continued to rise to 220 & lt; 0 & gt; C,After the potassium thiocyanate was completely melted, the water was distilled off for 1.0 hour,The reactor was then cooled to below 40 ° C,After the solidification of potassium thiocyanate, the reactor was filled with nitrogen to a micro pressure level of 0 to 0.3 kPa,62 g of ethylene carbonate was added,Slow warming,The reactor was heated to 80 & lt; 0 & gt; C in 15 minutes,The mixture in the reactor begins to react with ethylene sulfide,The reaction was maintained at 80 ° C for 1 hour,The reactor was heated to 100 & lt; 0 & gt;The distillation was completed when the reactor temperature reached 130 ° C,Condensation with ethylene glycol at -5 ° C gave 41.3 g of ethylene sulfide,Ethylene sulfide exhaust gas adsorption device to collect 0.2g ethylene sulfide,The reaction yield was 97.70%.
