摘要:
A method is provided for removing traces of heavy metals from concentrated alkali metal chloride solutions down into the range of 0.01 ppm by coprecipitation from an acidic concentrated alkali metal chloride solution with iron oxide hydrate.
摘要:
A process for electrolytically producing an amalgam from metal salt, using an anion exchanger membrane. The chlorine-free process provides amalgam produced from metal salt and having a high degree of purity, and ensures advantageous parameters, such as a low cell voltage and high current efficiencies.
摘要:
A process for preparing alkali metal alkoxides of alcohols comprising reacting an alkali metal amalgam with an alcohol having at least 3 carbon atoms in the presence of a powder catalyst comprising a transition metal carbide, nitride or carbonitride, to form a reaction mixture, wherein the reaction mixture is subjected to ultrasound during reaction.
摘要:
A process for preparing an alkali metal alkoxides by reacting an alkali metal amalgams and alcohols in the presence of a catalysts comprising a transition metal carbide, nitride or carbonitride, where the catalyst is in the form of a powder.
摘要:
Catalysts used for the catalytic preparation of alkali metal alkoxides from the alcohol and alkali metal amalgams are selected from the group consisting of carbides and nitrides of metals of group VIa of the Periodic Table, and titanium carbide.
摘要:
A process is described for the catalytic preparation of alkali alcoholates from alkali amalgams and alcohols. The catalyst is lump anthracite having a surface treated to have a heavy metal oxide or mixtures of heavy metal oxides. Preferably a mixture of nickel oxide and molybdenum oxide is used. Aliphatic alcohols with 1 to 4 carbon atoms are preferred as the alcohol component.
摘要:
A system and appertaining method provide a user interface application whose design is optimally modular and can be simply serviced and expanded on, and offers and optimally “free” configuration in order to cover all types of system conditions. A GUI file comprising description of graphical elements and appertaining identifiers is used to permit field changes by non-software developers without rebuilding any software. A similar communications file comprising communications parameters is provided that permits linkage to the GUI file by utilizing identifiers in common with those of the graphical elements in the GUI file.
摘要:
The present invention concerns a method for the purification and/or electrolysis of an aqueous potassium chloride solution, in which the sulphate ions are removed from the aqueous potassium chloride solution by precipitation as potassium sulphate and/or as a potassium sulphate-containing salt mixture and/or as a potassium sulphate-containing compound.
