Popis

Application

Levulinic acid is a precursor for the synthesis of useful intermediates such as γ-valerolactone, ethyl levulinate, pentanoic acid and 2-methyl-tetrahydrofuran. Derivatization and esterification of levulinic acid results in potential biofuels.

It can also be used in:

• The preparation of catalytic composite to synthesize 5-hydroxymethylfurfural and furfural.
• The synthesis of a commercial fragrance, fraistone.
• The synthesis of pyrrolidone derivatives via reductive amination.
• The total synthesis of mycobacterial arabinogalactan.
