Abstract
A method to make delta-valerolactone (“DVL”) by dehydrogenating 2-hydroxytetrahydropyran (“HTHP”). The HTHP is contacted with a supported-metal catalyst for a time, at a temperature, and at a pressure wherein at least a portion of the HTHP is converted to DVL via dehydrogenation of the HTHP. The HTHP may be derived from biomass. Thus, the method yields DVL without requiring a petroleum-based feedstock.
Claims21
A method to make delta-valerolactone (DVL), the method comprising dehydrogenating 2-hydroxytetrahydropyran (“HTHP”) by contacting HTHP with a supported-metal catalyst for a time, at a temperature, and at a pressure wherein at least a portion of the HTHP is converted to DVL.
A method to extract 2-hydroxytetrahydropyran (HTHP) from an aqueous solution, the method comprising:
- adding tetrahydropyran (THP) to the aqueous solution to form a water phase and a THP phase, wherein the HTHP enters the THP phase;
- and
- separating the water phase from the THP phase.
