  • Production of 1,5-pentanediol via upgrading of tetrahydrofufuryl alcohol
    Patent number: 10183904
    Abstract: A method of making 1,5-pentanediol from tetrahydrofurfural alcohol. The method includes the steps of dehydrating tetrahydrofurfural alcohol (THFA) to dihydropyran (DHP); hydrating at least a portion of the DHP to 2-hydroxy-tetrahydropyran (2-HY-THP) in the absence of homogeneous acid; and hydrogenating at least a portion of the 2-HY-THP to 1,5-pentanediol. The method can be conducted entirely in the absence of noble metal catalysts.
    Type: Grant
    Filed: January 22, 2016
    Date of Patent: January 22, 2019
