Malonic acid CAS# 141-82-2

Malonic acid (MA), additionally acknowledged as propanedioic acid, is a dicarboxylic acid with shape CH2(COOH)2. It have three types of crystal forms, of which two are triclinic, and one is monoclinic. That crystallized from ethanol is white triclinic crystals.It decomposes to acetic acid and carbon dioxide at 140℃. It does no longer decompose at 1.067×103~1.333×103Pa vacuum, however at once sublimates. The ionised shape of malonic acid, as properly as its esters and salts, are recognized as malonates. For example, diethyl malonate is malonic acid’s ethyl ester. The identify originates from Latin malum, which means apple.
