  • Alkyl Pyridinium Dicyanamides and Method For The Production Thereof
    Publication number: 20120330023
    Abstract: Alkylpyridinium dicyanamide of the formula: in which Rn1 is cyano or C1-20-alkyl and n is an integer from 0 to 3 and any R1 radicals present are the same or different, and in which R2 is C1-20-alkyl. There are processes for their preparation from alkylpyridinium halides and alkali metal dicyanamide, They can be used as polar solvents.

  • Process for preparing alkali metal or alkaline earth metal tricyanomethanides
    Patent number: 8022242
    Abstract: The present invention relates to a process for preparing highly pure alkali metal or alkaline earth metal tricyanomethanides.
    Type: Grant

    Assignee: Lonza AG
    Inventors: Christoph Täschler, Andreas Breuer
  • Method For the Production of a Thioacetic Acid and Salts Thereof
    Publication number: 20080161597
    Abstract: The invention relates to a method for the production of an thioacetic acid and salts thereof of formulae (I) and (II), wherein Mn+represents ammonium or an alkali metal cation, alkaline earth metal cation, aluminum cation or titanium cation, by reacting ketene with hydrogen sulphide in the presence of a nitrogenous base or reacting ketene with an aqueous alkali metal hydrogen sulphide solution. The thioacetic acid thus formed can be, optionally, subsequently transformed into the corresponding salt by reacting it with ammonia or an alkali metal base, alkaline earth metal base, aluminum base or titanium base. The transformation of thioacetic acid and the formation of salt is carried out as a one-pot method.
