Yield: 88%

Reaction Conditions:

with SiO2-Al2O3 catalyst at -8 - 70; under 1500.15 Torr;Large scale;Temperature;Pressure;Reagent/catalyst;

Steps:

2 Example 2
Proceed as followsTetrahydrofurfuryl alcoholEther:(1)1200 kg tetrahydrofurfuryl alcoholAnd 1500 kg of ethanol,At a flow rate of 25 kg / hA refrigerated-tube reactor in which a solid catalyst SiO2-Al2O3 is charged,The treated space velocity of the solid catalyst is 4h-1,At -8 ,0.2Mpa under full conditions of reaction,Again at a flow rate of 25 kg / hA non-packed heat pipe reactor is input,At 70 ,0.2Mpa under full conditions of reaction,Output reactant;(2)The reaction was run at a flow rate of 200 kg / hInput dehydration drying system,Followed by dehydration dehydration pump,After the drying bed was dried,To obtain a dehydrated dry product having a water content of 0.08%(3)The dehydrated dry product was flowed at a rate of 200 kg / hInput rectification system,A fraction of 135 to 165 ° C was collected,To give 1056 kg of the final product.Using the detection method in Example 1 to final product testing.From the test results,The final product is tetrahydrofurfuryl alcohol ether,Purity 99%,Tetrahydrofurfuryl alcohol in tetrahydrofurfuryl alcohol ether yield 88%.
