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. It is the simplest member of the ketene class. It is an important reagent for See more In industrial chemistry, ketene is produced by the dehydration reaction of acetic acid: On a laboratory scale it can be produced by the thermal … See more Exposure to concentrated levels causes humans to experience irritation of body parts such as the eye, nose, throat and lungs. Extended toxicity testing on mice, rats, guinea pigs and rabbits showed that ten-minute exposures to concentrations of freshly generated … See more • Media related to Ethenone at Wikimedia Commons See more Ethenone is a highly reactive gas (at standard conditions) and has a sharp irritating odour. It is only reasonably stable at low temperatures (−80 °C). It must therefore always be prepared for each use and processed immediately, otherwise a dimerization to See more Ethenone has been observed to occur in space, in comets or in gas as part of the interstellar medium.
