Procedure

The process for preparing tetrahydrofuran according to claim 1, wherein 1,4-butanediol is prepared by hydrogenating 1,4-diacetoxybutene, which is produced by the acetoxylation of butadiene, into 1,4-diacetoxybutane and hydrolyzing said 1,4-diacetoxybutane as the hydrogenated products in the presence of a solid acid catalyst and distilling hydrolyzates thus obtained.
