MANUFACTURE OF 3-METHYL-TETRAHYDROFURAN FROM ALPHA-METHYLENE-GAMMA-BUTYROLACTONE IN A TWO STEP PROCESS |
摘要 |
<p>Disclosed is a two-step, continuous hydrogenation process for the preparation of 3-methyl-tetrahydrofuran from alpha-methylene-gamma-butyrolactone, which comprises a first step of subjecting alpha-methylene-gamma-butyrolactone to hydrogenation to synthesize 2-methyl-gamma-butyrolactone; and the second step of hydrogenating the 2-methyl-gamma-butyrolactone formed in the first step. The above process enables the production of the objective highly-pure 3-methyl-tetrahydrofuran free from alcohol in high efficiency and high conversion through simple production steps.</p> |
