This invention provides a process for producing tetrahydrofuran by the reaction of 3-(5'-alkyl-1',3'-dioxane)propionaldehyde and/or 3-(5'-alkyl-1',3'-dioxane)propanol and/or 4-hydroxybutanal with hydrogen in an aqueous medium having a pH between about 0.1 and 5. Maintenance of the reaction medium within the specified acidic range of pH is an important feature of the invention process.
