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.
