Description

Verfahren zum Haltbarmachen von lVLetaldehyd. Nach dem Hauptpatent 394647 eignet- sich zum Iraltbarmachen von Metaldehyd gegen höhere Temperaturen besonders gut eine Behandlung mit gasförmigem verdünnten AmmoDiak.Process for the preservation of IV letaldehyde. According to the main patent 394647 is suitable for rendering metaldehyde non-recyclable against higher temperatures a treatment with gaseous, diluted AmmoDiak is particularly good.

Es wurde nun gefunden, daB Ammoniumcarbonat die gleiche Wirkung hat wie Ammoniak, aber in bezug auf die Durchführung des Verfahrens Vorteile aufweist. Man braucht nämlich nur dem. Metaldehydpulver vor dem Pressen die für den gewünschten Grad der Haltbarkeit nötigen geringen. Mengen Ammoniumcarbonat zuzumischen.It has now been found that ammonium carbonate has the same effect like ammonia, but has advantages with respect to the implementation of the process. You only need that. Metaldehyde powder before pressing those for the desired Degree of durability required low. Mix in quantities of ammonium carbonate.
