Participants

Reaction Steps

One or more objects of the present invention are accomplished by the provision of a process for producing tetrahydrofuran which comprises (1) condensing 2-methyl-1,3-propanediol with acrolein to form 2-vinyl-5-methyl-1,3 dioxane; (2) converting the 2-vinyl-5-methyl-1,3-dioxane under hydroformylating conditions to a mixture of 2(5'-methyl-1',3'-dioxane)propionaldehyde and 3-(5'-methyl-1',3'-dioxane)propionaldehyde; and (3) hydrogenating said mixture of propionaldehydes in the presence of a hydrogenation catalyst and water in a reaction medium having a pH between about 0.1 and 5 to yield tetrahydrofuran and 2-methyl-1,3-propanediol.
