Abstract

A process for preparing 4-hydroxymethyltetrahydropyran comprises reacting tetrahydrofurans of the general formula I ##STR1## where R.sup.1 is hydrogen, C.sub.1 - to C.sub.6 -alkyl or --CO--R.sup.2, and PA1 R.sup.2 is hydrogen or C.sub.1 - to C.sub.6 -alkyl, at from 0.degree. to 400.degree. C. and from 0.001 to 400 bar in the presence of acidic catalysts.
