    Abstract: 1401891 Removing metals from solutions; gas separation STAMICARBON BV 14 June 1973 [17 June 1972 1 May 1973 17 May 1973] 28383/73 Headings C1A and C1C [Also in Division C3] Metal values are removed from solutions or gaseous mixtures containing them by contacting the solution or mixture with a reduced keratin, a Bunte salt of a keratin or a natural or synthetic polyamide having at least some of the amide groups replaced by thioamide groups, which binds the metal values to the contacting agent. The keratin may be in the form of wool or fowls' feathers and can be converted to the Bunte salt by reaction with an alkali metal or alkaline earth metal sulphite with a tetrathionate as oxidant. The amide groups of a natural or synthetic polyamide can be replaced by thioamide groups by reaction of the polyamide with phosphorus pentasulphide. The process may particularly be applied to aqueous effluents.

    Abstract: The invention comprises 2-chloro-azacyclo-2,3 - hexene - N - carbochloride and 2-chloro-azacyclo-2,3-octene-N-carbochloride and their preparation by reacting in the liquid phase phosgene with d -valerolactam and #z-enantholactam, respectively, the lactam reactant being used (1) as such, and while ensuring that at all or substantially all times during the reaction there is an excess of the phosgene over the stoichiometric amount (i.e., a molar ratio of phosgene to lactam of more than 2 : 1), or (2) as the hydrochloric acid salt. Specification 901,169 also is referred to.

    Abstract: A process for the preparation of a catalyst system having a catalytically active component of an oxide, metal or alloy of one or more of the elements copper, zinc, cadmium, nickel, cobalt, iron, manganese or magnesium, homogeneously dispersed over a solid particulate inorganic thermostable carrier material, wherein the catalytically active component is precipitated onto the carrier material from an acid aqueous solution of a complex of an alpha -, beta -, or gamma -amino acid, an amino-sulphonic acid, or derivatives of such acids, with one or more of such elements, by gradually and homogeneously generating hydroxyl ions within the solution while maintaining the absence of free ammonia.
