Reaction Conditions:

with sodium methylate in methanol at 100; for 5 h;Temperature;Time;

Steps:

1-10 Example 3

In a 1 L lined autoclave,Add 400g butyrolactone,Concentrated sulfuric acid 9.30g,Mix and stir well,Warm up to 50°C,Pass in dimethyl ether to open the ring,During the feeding process, maintain the reaction temperature at 50°C,The pressure is stable at 0.2Mpa,The feeding time is 3h, and the weight gain of the reactor is 166.04g,Stop taking dimethyl ether,Keep warm for 20h,After the reaction is completed, cool to room temperature, exhaust the pressure,Add 134.55g of sodium methoxide methanol solution,Warm up to 100, keep for 5h,Cool to room temperature, transfer out the reactor materials, and weigh them,The content of the product was 51.11% detected by the internal standard method, the total mass was 768.32g, and the calculated yield was 98.18%.
