(EN) METHOD FOR THE PRODUCTION OF ONIUM ALKYL SULFITES
(FR) PROCEDE DE PREPARATION D'ALKYLSULFITES D'ONIUM
Abstract:
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung von Onium-Alkylsulfiten durch Umsetzung eines Onium-Halogenids oder -Carboxylats mit einem symmetrisch substituierten Dialkylsulfit oder mit einem unsymmetrisch substituierten Dialkylsulfit bei Temperaturen von 0 bis 70°C.
(EN) The invention relates to a method for producing onium alkyl sulfites by reacting an onium halide or onium carboxylate with a symmetrically substituted dialkyl sulfite or a non-symmetrically substituted dialkyl sulfite at temperatures ranging from 0 to 70 °C.
(FR) Procédé de préparation d'alkylsulfites d'onium par mise en réaction d'un halogénure ou carboxylate d'onium avec un dialkylsulfite à substitution symétrique ou avec un dialkylsulfite à substitution asymétrique, à des températures situées entre 0 et 70 °C.
