    "patent_abstract": "A system and method for removing acetaldehyde from an acetic acid system are disclosed. The method includes, providing a light-ends stream, comprising carbon monoxide, carbon dioxide, acetaldehyde, methyl iodide, methyl acetate, water, acetic acid, or mixtures thereof; condensing the light-ends stream to form one or more liquid phase compositions and a vapor phase composition, comprising a majority of the carbon monoxide and carbon dioxide and a minor portion of the acetaldehyde, methyl iodide, water, and acetic acid; contacting the vapor phase composition with a solvent to produce a liquid stream, comprising methyl iodide, acetaldehyde, and a portion of the solvent; and contacting the liquid stream, and optionally a polyol compound, with an acid catalyst to convert a portion of the acetaldehyde to an aldehyde derivative having a higher boiling point than acetaldehyde.",
    "precision_class": "structural",
    "invention_explanation": "A separation process that cools and condenses the reactor’s light gases so acetaldehyde can be removed while carbon monoxide and carbon dioxide remain mostly in the vapor.",
