Die vorliegende Erfindung betrifft ein Verfahren zur Stabilisierung von Mangan(ll)-äthylen-bis-dithiooarbamat mit Dimethylolharnstoff sowie die Mittel auf der Basis von mit Dimethylolharnstoff stabilisiertem Mangan(ll)-äthylen-bis-dithiocarbamat. The present invention relates to a method of stabilization of manganese (II) -ethylene-bis-dithiooarbamate with dimethylolurea as well as the means based on with dimethylolurea stabilized manganese (II) -ethylene-bis-dithiocarbamate.
Es ist bekannt, daß Mangan(II)-äthylen-bis-difchiooarbamat sich, bei der Lagerung nach und nach zersetzt, was eine Erniedrigung des Anfangsgehalts und die Gefahr mit sich bringt, da3 das Produkt mit der Zelt seine Antlfungus-Wlrkung verliert. Zur Verzögerung dieser Zersetzung wurde bisher die Zugabe verschiedener Stabilisierungsmittel vorgeschlagen.It is known that manganese (II) ethylene-bis-difchiooarbamate gradually decomposes during storage, which is a degradation the starting salary and the risk that 3 the product loses its anti-fungus effect with the tent. In order to delay this decomposition, the addition of various substances has hitherto been used Suggested stabilizers.

ein besonders Interessantes Stabilisierungsmittel für Hangan(II)-äthylen-bis-dithlocarbamat ist. Der Dimethylolharnstoff kann nach üblichen Arbeitsweisen auf trockenem Weg oder auf nassem Wege eingebracht werden. Im allgemeinen ist es vorteilhaft, dieses Einbringen auf nassem Wege zu bewerkstelligen, um eine bessere w Stabilisierungswirkung zu erzielen. Man kann Mengen an Dliaethylolharnstoff zwischen 0,1 und 10 Gew.-#, bezogen auf das Mangansalz, verwenden. Üblicherweise verwendet man vorzugsweise Mengen zwischen 1 und 5 #is a particularly interesting stabilizing agent for Hangan (II) -ethylene-bis-dithlocarbamate. The dimethylolurea can be introduced dry or wet in accordance with customary procedures. In general, it is advantageous to accomplish this incorporation by the wet method, in order to achieve a better w stabilizing effect. Amounts of Dliaethylolurea between 0.1 and 10 wt .- #, based on the manganese salt, can be used. Usually, amounts between 1 and 5 # are preferably used
Das folgende Beispiel erlfiutez-E die Erfindung, ohne sie zu beschränken. The following example illustrates the invention without restricting it.
a) Man bringt in eine 7-1-MUhle, die zu 2/5 mit zyllndrieehkugellgen Körpern mit einem Durchmesser von 20 mm und einer Länge von 25 mm gefüllt ist, 1200 g frinch ausgefälltes, mit 10β5 g Wasser benäßtes Mangan(II)-äthylen-bis-dithiocarbamat ein. Man setzt 715 g Viassar, 59,6 eines Dispergiermittels vom Naphthylmethansulfonat-Typ und ho g Dimethylolharnstoff zu.a) One brings 1200 g of frinch-precipitated manganese (II), wetted with 10β5 g of water, into a 7-1 mill, 2/5 of which is filled with cylindrical bodies with a diameter of 20 mm and a length of 25 mm - ethylene-bis-dithiocarbamate. 715 g of Viassar, 59.6 g of a dispersant of the naphthyl methanesulfonate type and ho g of dimethylolurea are added.

fluiden Brühe. Diese Brühe wird durch Sprühen In einen Trockner bei 135 biß 7QX behandelt, um ein Pulver mit weniger als 5j( Wasser zu erhalten. Man erhKlt so II80 g Pulver mit einem Gehalt von zumindest 5% Wasser und von 3# Dlmethylolhametof f.fluid broth. This broth is treated by spraying in a drier at 135 to 7QX in order to obtain a powder with less than 5% of water. This gives 80 g of powder containing at least 5% water and 3% methylolhamethane.
b) Nach der gleichen Arbeiteweise stellt man ein Mangan(II)-Hthylen-bis-dithiocarbamatpulver, Jedoch ohne Netzmittel und ohne Dimethylolharnstoff her.b) A manganese (II) -ethylene-bis-dithiocarbamate powder is prepared in the same way, However, without wetting agents and without dimethylolurea.
c) und d) Nach der gleichen Arbeitsweise wie unter a) stellt man 2 ManganCllJ-Mthylen-biS-dithioearbamatpulver her, bei denen man die 40 g Dimethylolhamstoff durch 53 g Dlmethylolharnetoff bzw. 53 g Hexamethylentetramin ersetzt. Man erhält so die Probe (c) mit h% Dimethylolharnstoff und die Probe (d) mit 4$ Hexamethylentetramin« einem bekannten Stabilisierungsmittel für Mangan(II)-Äthylen-bis-dlthiocarbamat.c) and d) The same procedure as under a) is used to prepare 2 ManganCIIJ-Mthylen-bis-dithioearbamatpulver in which the 40 g of dimethylolurea are replaced by 53 g of dimethylol urea or 53 g of hexamethylenetetramine. This gives sample (c) with 1% dimethylolurea and sample (d) with 4% hexamethylenetetramine, a known stabilizing agent for manganese (II) ethylene bis-thiocarbamate.
Diese Proben a), b), c) und d) werden bei 7OT gelagert, und ihre Gehaltsabnahme wird in verschiedenen ZeitabstKnden durch Bestimmung des verschwundenen Schwefelkohlenstoffs gemessen.These samples a), b), c) and d) are stored at 7OT, and their wage decrease will occur at different time intervals Determination of the disappeared carbon disulfide measured.
