  • Recovery of isophthalonitrile
    Patent number: 4134910
    Abstract: Isophthalonitrile (IPN) is recovered from an isophthalonitrile production reaction effluent, which contains water vapor, by direct contact quenching of the effluent with an organic quench liquid to cool the effluent to a temperature at which essentially all of the isophthalonitrile is condensed as a solution in the organic quench liquid, without condensation of water vapor. In this manner, isophthalonitrile is recovered from the effluent and separated from water vapor, thereby preventing the liquid phase hydrolysis of IPN which occurred in prior art procedures.
