ketene
any of a class of organic compounds containing the functional grouping CCO; the most important member of the class being ketene itself, CH2CO, which is used in the manufacture of acetic anhydride and other industrial organic chemicals. The name suggests that ketenes are unsaturated ketones, but their chemistry resembles that of carboxylic acid anhydrides.
