ABSTRACT:
A process for producing tetrahydrofuran, 1,4-butanediol, and 2-methyl-1,3,-propanediol is disclosed. A mixture containing 4-hydroxybutanal and 3-hydroxy-2-methylpropanal is hydrogenated in the presence of a transition metal supported on a weakly acidic ion-exchange resin or zeolite-type material to give tetrahydrofuran as the major product, and 1,4-butanediol and 2-methyl-1,3-propanediol as minor products. High yields of 2-methyl-1,3-propanediol can be obtained.
