【 摘 要 】

References(26)Cited-By(1)A simple method for estimating the Wilson parameters from pure component properties alone previously proposed has been adopted to predict the vapor–liquid equilibria of binary systems containing carboxylic acids such as acetic acid. Carboxylic acid vapors are characterized by the presence of large amounts of dimers. The binary mixtures of non-associating substance+carboxylic acid and carboxylic acid+carboxylic acid have been studied. The prediction performances obtained are examined and discussed.
