Process for the preparation of high-purity tetrahydrofuran |
| abstract |
Disclosed is a process for the preparation of high-purity tetrahydrofuran from a mixture of 2,5-dihydrofuran and 3,4-epoxy-1-butene and/or crotonaldehyde wherein the mixture is hydrogenated in the presence of a nickel or platinum catalyst to obtain a product consisting essentially of tetrahydrofuran and 1-butanol which are readily separable. |
