APPLICATIONS |
||
| Malonic acid (also called Propanedioic Acid ) is a white crystalline dicarboxylic acid; melting at 135 -136 C; readily soluble in water, alcohol and ether; solution in water is a medium strong acid. It can be derived by oxidizing malic acid or by the hydrolysis of cyanacetic acid. Malonic acid itself is rather unstable and has few applications. It's diethyl ester (diethyl malonate) is more common commercially. Diethyl malonate, a colourless, fragrant liquid boiling at 199 C, is prepared by the reaction of monochloroacetatic acid with methanol, carbon monoxide or by the reaction cyanoacetic acid (the half nitriled-malonic acid) with ethyl alcohol. Malonic acid, as well as its esters, is characterized by the large number of condensation products. They are important intermediates in syntheses of vitamins B1 and B6, barbiturates, and numerous other pharmaceuticals, agrochemicals and flavors & fragrances compounds. Diethyl butylmalonate is used as intermediate for pharmaceuticals especilly for non-steroidal anti-inflammatory agents and also used in the flavour and fragrance industries. | ||
