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.
