METHOD FOR PREPARING LEVULINIC ACID ESTERS Russian patent published in 2008 - IPC C07C69/72 C07C67/00 

Abstract RU 2319690 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to organic synthesis, in particular, to a method for synthesis of levulinic acid esters used as aromatizing agents in perfume, tobacco and food industry. Method for synthesis of levulinic acid esters of the general formula: wherein R means alkyl involves interaction of furfuryl alcohol with aliphatic alcohols in the presence of a catalyst wherein iron acetylacetonate Fe(acac)3 as catalyst. Reaction is carried out in CCl4 solution in the mole ratio [Fe(acac)3] : [furfuryl alcohol] : [ROH] : [CCl4] = 1:(50-200):(100-400):(100-400), respectively, at alcohol boiling point for 2-5 h. The yield of levulinic acid esters is 80-98%.

EFFECT: improved method of synthesis.
