Production Methods
This ester has been suggested for use in flavor compositions, but it is not sufficiently stable enough to become very popular. The ester has occasionally found use in perfume compositions, mainly as a modifier in fruity notes, winey top note bases, etc. Diethyl diethylmalonate is produced (several methods) e. g. by condensing Ethyl acetate with Ethyl oxalate, heat the resultant Oxaloacetic ester, and esterify the formed Diethyl malonic acid.
