- CAS Number:91-53-2
- Molecular formula:C14H19NO
- Molecular Weight:217.31
Yield:91-53-2 92%
Reaction Conditions:
at 60 - 110; under 760.051 Torr; for 8 h;Ionic liquid;Temperature;
Steps:
1; 2; 3; 4 Example 4
68.5 g of p-aminophenyl ether,20g of ionic liquid,It is metered into the reactor at one time, fully mixed, heated and heated,At a reaction temperature of 110 ° C,70 g of acetone was added dropwise under normal pressure,The reaction time is 8h,Reduce the temperature of the reaction solution to below 60 ° C.Unreacted acetone is condensed and recovered into the acetone recoverer;The reaction solution was washed with water to separate the lower catalyst aqueous solution, and the catalyst was recycled.The upper ethoxyquinoline feed liquid separated by washing with water was distilled to obtain a finished product, and the yield was 92%.
