Potassium hydrogenacetylenedicarboxylate
Encyclopedia
Potassium hydrogenacetylenedicarboxylate is a potassium
salt with chemical formula KC4HO4 or K+·HC4O4−, often abbreviated as KHadc. It is often called potassium hydrogen acetylenedicarboxylate or monopotassium acetylenedicarboxylate.
The salt can be obtained from acetylenedicarboxylic acid
and is a common laboratory starting material for the synthesis of other derivatives of that acid. In the crystalline form, the hydrogenacetylenedicarboxylate
anions HC4O4−s are joined into linear chains by uncommonly short hydrogen bonds.
Potassium
Potassium is the chemical element with the symbol K and atomic number 19. Elemental potassium is a soft silvery-white alkali metal that oxidizes rapidly in air and is very reactive with water, generating sufficient heat to ignite the hydrogen emitted in the reaction.Potassium and sodium are...
