  • Patent number: 4532354
    Abstract: The present invention relates to a method for purifying N,N-dimethylaminopropylamine containing 1,3-diaminopropane as an impurity. Dimethylaminopropionitrile is formed by adding dimethylamine to acrylonitrile, and is then converted by subsequent hydrogenation and distillation into N,N-dimethylaminopropylamine. The impurity 1,3-diaminopropane is removed by adding a metal salt of a transition element which forms a stable complex with the 1,3-diaminopropane.

  • Patent number: 4529550
    Abstract: Improvements in efficiencies and yields are achieved in the production of a saturated aliphatic monocarboxylic acid containing 5 to 9 carbon atoms from its corresponding aldehyde by rapidly hydrolyzing the anhydride of the monocarboxylic acid formed in the oxidation. The hydrolysis is accomplished by contacting the anhydride with water at a temperature from about 130.degree. C. to about 215.degree. C. and at a pressure under which the water is maintained in the liquid state to convert the anhydride to its corresponding acid.

  • Patent number: 4529551
    Abstract: This invention comprises a process for separating oleic acid from a feed mixture comprising an oleic acid and linoleic acid, which process comprises contacting the mixture at separation conditions with a molecular sieve comprising silicalite, thereby selectively retaining the oleic acid. The oleic acid is recovered from the molecular sieve by displacement with a displacement fluid comprising a diluent soluble in the feed mixture and having a polarity index of at least 3.5. Displacement occurs at a temperature from about 120.degree. C. to about 150.degree. C. The feed mixture may also contain rosin acids in which case a first molecular sieve comprising silicalite is used to separate the fatty acids from the rosin acids.
