| 摘要 |
The present invention relates to a process for the catalytic hydrogenation of 1,4-butynediol to tetrahydrofuran at at least the decomposition temperature of 1,4-butynediol, wherein 1,4-butynediol is vaporized in a hydrogen-comprising gas stream and is hydrogenated in gaseous form over at least one catalyst, comprising at least one of the elements from groups 7 to 11 of the Periodic Table of the Elements. |
