The invention relates to a process for eliminating nitrogenous organic compounds from a salt-containing water which contains more than 0.5% by weight of salt in the form of CaClor NaCl, less than 200 ppm of dissolved carbonic acid or carbonates and more than 50 ppm of nitrogenous organic compounds, by treating the water by wet oxidation at a temperature of below 100&#xb0; C. with chlorine or a chlorine-containing oxidizing agent and feeding this, preferably after additional oxidation with a gaseous oxidizing agent and/or by adsorption with an adsorbent, to an electrolysis for producing chlorine and/or sodium hydroxide solution.

Pigment preparations

In the process for the preparation of microcapsule dispersions by an interface polyaddition process in which an oil-in-water emulsion is prepared from an oily phase, which comprises the substance to be encapsulated and a lipophilic substance capable of polyaddition, and on aqueous phase, and the reaction partner required for the polyaddition is then added to the aqueous phase, capsules with smaller particle sizes are obtained, with a saving in emulsifying energy, if an oil-soluble emulsifier is added to the oily phase before the emulsification.

Process for microencapsulation using oil-soluble emulsifiers

The invention relates to new, free-flowing polyamide molding compounds and blends, characterized in that they are prepared by mixing of polyamides known per se in the melt with low molecular weight, liquid-crystalline esters and/or ester amides corresponding to formula (I) and/or liquid-crystalline, oligomeric esters and/or ester amides corresponding to formula (II) and, optionally, other additives, at least one polymeric blending component being used as a further additive in the case of polyamide blends, and to the use of these liquid-crystalline (LC) additives I and/or II as flow promoters in polyamide molding compounds and blends and to a process for the production of the new polyamide molding compounds and blends. The invention also relates to the new oligomeric esters and/or ester amides corresponding to formula (II).
