    Abstract: Tetrahydropyran-4-carboxylic acid and its esters of the general formula I in which R denotes hydrogen, C1- to C6-alkyl, C5- to C8-cycloalkyl or aryl, are prepared by reacting dihydro-2(3H)furanones of the general formula II in which R denotes hydrogen, C1- to C6-alkyl or -CO-R and R denotes hydrogen or C1- to C6-alkyl with water or alcohols of the general formula III R -OH (III> in which R has the abovementioned meaning, at temperatures from 200 to 350 DEG C in the presence of acidic heterogeneous catalysts, by employing fixed-bed acidic heterogeneous catalysts.
