Ethenone is used to make acetic anhydride from acetic acid. Generally it is used for the acetylation of chemical compounds. Ethenone reacts with methanal in the presence of catalysts such as Lewis acids (AlCl3, ZnCl2 or BF3) to give β-propiolactone. The technically most significant use of ethenone is the synthesis … See more In organic chemistry, ethenone is the formal name for ketene, an organic compound with formula C2H2O or H2C=C=O.
