| DIETHYL DIETHYLMALONATE Usage And Synthesis |
Chemical Properties |
clear colorless liquid. Quite powerful, fruity, Pear-like odor.
| Uses | Diethyl Diethylmalonate is an intermediate in the synthesis of Barbital (B118500), a prototype of the barbiturate hypnotics. | Uses | manufacture of barbiturates. | 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.
