2-methyl tetrahydrofuran brief introduction
2-甲基四氢呋喃是一种有机化合物,分子式为CH3C4H7O。它是一种高度易燃的流动液体。它主要在特殊应用中用作 THF 的替代品,以获得更好的性能,例如获得更高的反应温度或更容易分离(因为与 THF 不同,它不与水混溶)。它来源于糠醛,可用作生物燃料。

Production method and purpose
Production method
Obtained by catalytic hydrogenation of 2-methylfuran. When palladium chloride catalyst is used for catalytic hydrogenation reaction, the main product is acetyl propanol (see 00420), but the by-product 2-methyltetrahydrofuran can also be recovered.
use to
Used as an intermediate for pharmaceutical chloroquine phosphate.
