Abstract: 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.

Abstract: Novel 2-aminopyrazines and processes for the preparation of 2-aminopyrazines and pyrazines by reaction of an alpha -iminodiacetonitrile (a) with a hydrogen halide or (b) with an alcohol or a thioalcohol and a hydrogen halide or (c) with an alcohol or a thioalcohol in the presence of an alkali metal compound and/of an alkaline earth metal compound. The 2-aminopyrazines and pyrazines obtainable by the process of the invention are useful starting materials for the preparation of dyes, fungicides, bactericides, textile assistants, scents, folic acid derivatives, flavorings, and active ingredients in crop protection and drugs.
