Acetone

The merchandise covered by this investigation is all grades of liquid or aqueous acetone. Acetone is also known under the International Union of Pure and Applied Chemistry (IUPAC) name propan-2-one. In addition to the IUPAC name, acetone is also referred to as [szlig]-ketopropane (or beta-ketopropane), ketone propane, methyl ketone, dimethyl ketone, DMK, dimethyl carbonyl, propanone, 2-propanone, dimethyl formaldehyde, pyroacetic acid, pyroacetic ether, and pyroacetic spirit. Acetone is an isomer of the chemical formula C3H6O, with a specific molecular formula of CH3COCH3 or (CH3)2CO. The scope covers both pure acetone (with or without impurities) and acetone that is combined or mixed with other products, including, but not limited to, isopropyl alcohol, benzene, diethyl ether, methanol, chloroform, and ethanol. Acetone that has been combined with other products is included within the scope, regardless of whether the combining occurs in third countries. The scope also includes acetone that is commingled with acetone from sources not subject to this investigation. For combined and commingled products, only the acetone component is covered by the scope of this investigation. However, when acetone is combined with acetone components from sources not subject to this investigation, those third country acetone components may still be subject to other acetone investigations. Notwithstanding the foregoing language, an acetone combination or mixture that is transformed through a chemical reaction into another product, such that, for example, the acetone can no longer be separated from the other products through a distillation process (e.g., methyl methacrylate (MMA) or Bisphenol A (BPA)), is excluded from this investigation. A combination or mixture is excluded from these investigations if the total acetone component (regardless of the source or sources) comprises less than 5 percent of the combination or mixture, on a dry weight basis. The Chemical Abstracts Service (CAS) registry number for acetone is 67-64-1.
