FRAMSTAELLNINGSFOERFARANDE FOER REAKTIONSPRODUKTER AV CYANVAETE.

摘要

Reaction products of hydrogen cyanide are prepared by a process in which hydrogen cyanide prepared in a conventional manner by pyrolysis at from 250 DEG to 650 DEG C. over a solid under from 5 to 200 mbar is cooled to a temperature of from 200 DEG to -10 DEG C. together with the other pyrolysis products, the hydrogen cyanide is then fed to a chemisorption reaction with a base or with a carbonyl compound, and the reaction products of hydrogen cyanide which are formed therein are removed from the system and brought to atmospheric pressure. In this process, the handling of large amounts of hydrogen cyanide is avoided.
