Chemical Properties

Butyl levulinate has a sweet and slightly pungent caramellic odor with fruity undertones; mild sweet caramellicherbaceous taste; bitter taste.

Uses

Butyl 4-Oxopentanoate is used in preparation and application of magnetic nano-solid acid catalyst iron oxide-polydopamine-sulfonic acid

Uses

Butyl levulinate can be used in flavor compositions for imitation Butter, Rum, and in various fruit flavors, "Tutti-frutti", etc. Concentration is usually mere traces (a few ppm. ) in the finished product.

Production Methods

Butyl levulinate can be produced by direct esterificalion of n-Butyl alcohol with Levulinic acid.

Definition

ChEBI: Butyl levulinate is an oxo carboxylic acid.
