  • Patent number: 5108585
    Abstract: A collecting agent and method for the recovery of valuable minerals in the froth flotation beneficiation of non-sulfidic ores is provided. The collecting agent is selected from alkyl glycosides, alkenyl glycosides and mixtures thereof. Preferably, the collecting agent is a combination of an alkyl glycoside, an alkenyl glycoside and mixtures thereof with a non-thio ionizable surfactant collector. Glycosides containing from about 2 to 8 glycoside residues may be used. The alkyl and alkenyl components of these glycosides may be linear or branched, may contain from about 2 to 18 carbon atoms and may optionally contain a hydroxyl group or an ether linkage.

  • Patent number: 4889925
    Abstract: Mixtures of alkyl glycosides and fatty alcohols are readily separated by distillation without thermal degradation of glycoside. In the presence of one or more viscosity-reducing agents which are heat-stable and color-stable at temperatures of up to 160.degree. C., which are miscible with the alkyl glycosides, which have a boiling point at 760 mbar at least 50.degree. C. above the boiling point of the fatty alcohol present in the mixture, and reduce the viscosity of the mixture to at most 10,000 mPas at the distillation temperature. The fatty alcohols are quantitatively separated off from this mixture by distillation in customary distillation apparatus at a temperature at least 20.degree. C. below the thermal decomposition point of the alky glycosides and under pressures of from 1 to 10.sup.-3 bar.

  • Patent number: 4820436
    Abstract: Detergents on the basis of anionic and nonionic surfactants contain as laundering power-enhancing additives an aliphatic amine compound which is selected such that its pK.sub.b value is at least equal to 14, minus the initial pH value of a 1% aqueous solution of the detergent containing the amine compound. Laundering power-enhancing amine compounds selected according to the rule mentioned are certain ether amines, amidoamines, glucamine derivatives or morpholine derivatives.

  • Patent number: 4451261
    Abstract: This invention relates to a process for preparing sulfonated lubricating agents for leather and tanned furs consisting of the steps of:(a) chlorinating natural or synthetic higher fatty acids or esters of higher fatty acids having chain lengths of from 8 to 24 carbon atoms containing olefinically unsaturated fractions, up to saturation of the double bonds;(b) sulfochlorinating the chlorinated product from step (a) with chlorine and SO.sub.2 at a temperature of from about 20.degree. to 90.degree. C., optionally under UV-radiation, for a time sufficient to obtain a compound having a chlorine content of from about 5 to 30 percent by weight and a content of SO.sub.2 Cl groups of from about 1 to 20 percent by weight, the ratio of chlorine atoms to SO.sub.2 Cl groups being from about 0.7:1 to 70:1; and(c) saponifying the product from step (b) to form a water-emulsifiable alkali metal, ammonium, or lower alkyl-ammonium salt of the product of step (b).
