    Abstract: Present invention relates to a process and an installation (100) for the preparation of hydrogen cyanide by the Andrussow process, and more precisely for improving the conditions of mixing the reactant gases before feeding the Andrussow type reactor (60), in order to improve safety, to avoid any risk of explosion and to produce HCN in safe and efficient manner. The installation is configured in such a manner that oxygen is pre-mixed with air with a ratio comprised between 20,95% and 32,5% by volume, preferably between 25% and 30,5% by volume; methane containing gas and ammonia are simultaneously added in the pre-mixture of oxygen-enriched air in such a manner that the volumic ratio of methane to ammonia is comprised between 1,35 and 1,02 depending on the content of oxygen into air; said obtained reactant gases mixture having a temperature comprised between 80°C and 120°C, preferably between 95°C and 115°C for feeding the Andrussow type reactor (60).

    Abstract: Biphenyl-4-carbonitril der Formel (I) wird durch Umsetzung von Biphenyl mit Chlorcyan in Gegenwart von wasserfreiem Aluminiumchlorid hergestellt. Das Verfahren liefert das gewünschte Produkt in guter Ausbeute und ohne Bildung von isomeren oder mehrfach cyanierten Nebenprodukten. Biphenyl-4-carbonitril ist ein wichtiges Zwischenprodukt, beispielsweise in der Synthese von pharmazeutischen Wirkstoffen.

    Abstract translation: 联苯-4-甲腈的式(I)的通过与氯化氰在联苯无水氯化铝的存在下反应制备的。 该过程产生良好产率和不形成异构体或乘法氰化副产物的所需产物。 联苯-4-甲腈是一种重要的中间产物,例如在活性药物成分的合成。
