General description and preparation:
Levulinic acid, or 4-oxo-pentanoic acid, or b-acetylpropionic acid, or g-ketovaleric acid [123-76-2]
is an organic acid belonging to keto acids group. In its pure form, it is a white crystalline solid with melting point of 33 °C.
It is soluble in water and polar organic solvents. Despite its low toxicity (LD50
1850 mg/Kg, oral, rat), as other acids, it can cause the acid burns and high concentrated solutions are irritating to the skin and mucous membranes.
The name, levulinic acid (originally levulinsäure, in german) was suggested by A. v. Grote and B. Tollens in 1874 as it was prepared from L-sugar (L-fructose) known as levulose.
Levulinic acid can be produced by acid hydrolysis of 5-hydroxymethylfufural (5-HMF), or by transformation of biomass/cellulose via formation of monomeric sugar derivatives.
In 1953 Quaker Oats developed a continuous process to produce levulinic acid from carbohydrate material such as starch, cellulose, or sugars.
Application of Levulinic acid:
It can be used as a raw material in organic synthesis, especially in the production process of some pharmaceuticals, in the preparation of 5-methyl-2-pyrrolidone,
and angelica lactone.
It has been recently found to be useful in the production of plasticizers and its esters as fragrance ingredients (fraistone) are used in the cosmetics production.
LA was identified as one of the twelve promising bio-based building blocks that can be subsequently converted to a number of high-value chemicals, fuels or materials.
