    摘要: Odor formation during storage of (hydrocarbylthio)aromatic amines due to formation and release of odoriferous sulfur-containing species such as dihydrocarbyldisulfides, is suppressed. To accomplish this, a small amount of N,N-dihydrocarbylhydroxylamine odor-inhibitor (e.g., N,N-diethylhydroxylamine) is blended with the (hydrocarbylthio)aromatic amine. This enables products such as a mixture of 3,5-di(methylthio)-2,4-diaminotoluene and 3,5-di(methylthio)-2,6-diaminotoluene) to be stored for long periods of time with significantly reduced formation and release of odoriferous sulfur-containing species.

    摘要: Impure 2,6-diisopropylphenol (DIP) is purified by use of a distillation process in which a single distillation column is used. The process comprises: (a) subjecting the impure DIP to a first continuous distillation in the column in an inert environment to distill off lower boiling components and produce first column bottoms enriched in DIP; (b) collecting, cooling and storing the first column bottoms while continuously maintaining them in an inert environment; (c) discontinuing the first continuous distillation; (d) subjecting the first column bottoms to a second continuous distillation in an inert environment in the same column to produce a second overhead distillate composed of purified DIP. The process avoids the formation in the distilling mixtures of dose boiling impurities due to seepage of air through standard pipe flanges and fittings and consequent oxidation reactions which occur under the conditions needed for batch distillations conducted in typical industrial distillation facilities. These impurities include 2,6-diisopropylbenzoquinone, 2-isopropyl-6-isopropenylphenol, 2,6-diisopropenylphenol and 2,2-dimethyl-4-isopropyl-1,3-benzodioxole. The capital investment needed for a conventional continuous distillation facility is also avoided.
