Acetylenedicarboxylic acid Chemical Properties,Usage,Production

Chemical Properties

cream coloured to beige crystalline powder or

Uses

Acetylenedicarboxylic acid is employed in the preparation of dimethyl acetylenedicarboxylate and potassium hydrogenacetylenedicarboxylate. It is also used as a laboratory reagent. Further, it is used as a precursor in organic synthesis and also serves as a pharmaceutical intermediate.

Definition

ChEBI: An acetylenic compound that is acetylene in which the hydrogens are replaced by carboxy groups.

Purification Methods

The acid is soluble in Et2O and crystallises from Et2O/pet ether (m 183-183.5o), or H2O as the dihydrate which dehydrates in a desiccator over conc H2SO4 in a vacuum. The dipicrate crystallises from aqueous ether. For the mono K salt see entry in “Metal-organic Compounds”, Chapter 5. [Abbott et al. Org Synth Coll Vol II 10 1943, Huntress et al. Org Synth Coll Vol IV 329 1963, Beilstein 2 H 801, 2 I 317, 2 II 670, 2 III 1991, 2 IV 2290.]
