Product Application of Levulinic acid CAS#123-76-2

Levulinic acid is a biomass product and its derivatives, such as ethyl levulinate and alkyl levulinate, can be used as fuel additives.
levulinic acid is used for calcium levulinate in pharmaceuticals, as esters in solvents and plasticizers, and for making valerolactone. As its uses expand, it will probably be made from cellulosic wastes. Mesitonic acid, a homolog of levulinic acid is obtained by boiing mesityl oxide with KCN.
