Erläuterungen zum Harmonisierten System (HS) Zu dieser Position gehören, mit Ausnahme der in der Einleitung zu diesem Teilkapitel angeführten Verbindungen, die Cyanide, Cyanidoxide (Oxycyanide) und komplexen Cyanide. A. – Cyanide Cyanide sind die Metallsalze des Hydrogencyanids (Cyanwasserstoffsäure, Blausäure) (HCN) (Position 2811). Diese Salze sind sehr giftig. 1) Natriumcyanid (NaCN) wird hergestellt, entweder indem man Koks oder gasförmige Kohlenwasserstoffe mit Natriumcarbonat und Luftstickstoff umsetzt, oder indem man Calciumcyanamid der Pos. 3102 mit Holzkohle, oder aber auch indem man pulverisierte Kohle, Natrium und Ammoniak miteinander reagieren lässt. Es kommt als Pulver, Tafeln oder Paste vor, ist weiß, kristallin, hygroskopisch, leicht löslich in Wasser und hat einen Geruch nach Bittermandeln. In geschmolzenem Zustand nimmt es Sauerstoff auf; es kann auch Hydrate bilden. …
