  • Patent number: 4224247
    Abstract: An improved method for the recovery of para-aminophenol from crude solutions thereof such as obtained by the catalytic hydrogenation of nitrobenzene in an aqueous acid reaction medium. The method comprises neutralizing the cold, acidic solution containing the crude para-aminophenol whereby a very fine fluffy para-aminophenol precipitates. When an aromatic amine selected from the group consisting of aniline, mixed toluidines, ortho-toluidine, mixed xylidines, and mixtures thereof is admixed therewith an upper layer containing the para-aminophenol suspended in the aromatic amine forms when allowed to settle. A clear lower layer containing about 70 to 90% of the ammonium sulfate solution is separated and discarded. The upper layer which contains the aromatic amine and the para-aminophenol can be used as a source of para-aminophenol for producing para-aminophenol derivatives such as diaryl para-phenylenediamines.

  • Patent number: 4211577
    Abstract: Extraction of purified plant anthocyanin colors particularly from dark grapes by treating impure materials to insure discrete monomeric anthocyanin molecules in solution and then passing the solution through ultrafiltration membranes to retain soluble and/or cloudy macromolecular, e.g., colloidal, impurities upstream that produce, an aging, haze and sediments, and pass the monomeric anthocyanins downstream for further concentration as liquid or powder to give a stable color concentrate that can be used as a color additive. For example, fruit solids may be treated with sulfur dioxide solutions to ionize, decolor and insure the monomeric state of the pigment molecules (change from anthocyanins to chromon 2-and 4-sulfonates), ultrafiltering the solution to pass the anthocyanins downstream while retaining upstream the macromolecular components such as pectins, tannins, proteins, complexes thereof, etc.

  • Patent number: 4210424
    Abstract: Oil-soluble combinations of (A) ethylene polymer or copolymer, (B) normal paraffinic wax composed of normal hydrocarbons whose average molecular weight is within the range of from 300 to 650, and (C) nitrogen compounds, such as amides, amine salts and ammonium salts, of carboxylic acids or anhydrides, are useful in improving the cold flow properties of distillate hydrocarbon fuel oils. Preferably, the wax contains n-paraffins ranging from C.sub.23 to C.sub.37 inclusive. If desired, the combination can be usefully stabilized by the addition of one or more compatibility additives, i.e. a polymer having alkyl side chains of 6 to 30 carbon atoms and derived from carboxylic acid esters and/or olefins or C.sub.8 -C.sub.18 alkanol, e.g. tridecyl alcohol or mixtures of said polymer and alkanol.
