Description

Düngung Es ist bekannt, Melamin (2 . 4.6 . Trinitro r # 3 # 5 . Triazin) zu verschiedenen Zwecken zu verwenden, und zwar insbesondere zur Herstellung von Harzen, die man zu Maschinenteilen, Kunstharzleim, wasserfesten Papieren usw. verarbeiten kann. Außerdem werden Melaminharze zur Textilveredelung angewandt, und sie können infolge ihrer durchsichtigen Eigenschaft als Überzugmittel verwandt werden.Fertilization It is known to use melamine (2. 4.6. Trinitro r # 3 # 5. Triazine) to be used for various purposes, in particular for the production of Resins that are processed into machine parts, synthetic resin glue, waterproof papers, etc. can. Melamine resins are also used for textile finishing, and they can be used as a coating agent due to their transparent property.

Auf dem Düngemittelgebiet ist bisher die Verwendung von anunonnitrathaltigen Düngemitteln, Ammonsulfat sowie Harnstoff und Kalkstickstoff vorherrschend. Es sind bereits Produkte, die durch Erhitzen von Rhodanammonium, Thioharnstoff oder Guanidinrhodanid hergestellt werden, als Düngemittel vorgeschlagen worden. Der Anteil des in diesen Gemischen enthaltenen Melamins ist jedoch äußerst gering und beträgt etwa nur einige Prozente. Ferner ist gleichzeitig auch schon der Vorschlag gemacht worden, die in den Gemischen enthaltenen einzelnen Verbindungen, wie Melam oder Melem, für Düngezwecke zu verwenden. Die Verwendung von fertig hergestelltem Melamin als einwandfrei chemisch festgestellter Substanz für Düngezwecke ist dort jedoch nicht vorgesehen. Dabei ist noch zu berücksichtigen, daß das hergestellte Melam erst noch einer weiteren Behandlung bedürfte, um aus diesem Melamin zu bilden.In the field of fertilizers, the use of anunon nitrate has so far been used Fertilizers, ammonium sulfate, and urea and calcium cyanamide predominate. There are already products made by heating rhodanammonium, thiourea or guanidine rhodanide have been proposed as fertilizers. The proportion of in these Melamine contained in mixtures, however, is extremely small and amounts to only a few Percentages. Furthermore, the suggestion was made at the same time, which is specified in the mixtures contained individual compounds, such as melam or melem, for fertilization purposes to use. The use of ready-made melamine as perfectly chemically identified substance for fertilization purposes is not provided there. Included it has to be taken into account that the melam produced is still another Treatment would be required to turn this into melamine.

Weiter sind auch Düngemittel bekanntgeworden, welche durch Erhitzen von Harnstoff bis zur Beendigung der Ammoniakentwicklung entstehen. Dabei erhält man wohl Stoffe, welche der gleichen Gruppe wie Melamin angehören (Cyanursäure und Ammelid), die jedoch auch andere chemische Eigenschaften haben und außerdem auch einen viel geringeren Stickstoffgehalt aufweisen.Fertilizers have also become known which are produced by heating from urea to termination the development of ammonia. In doing so, you get substances that belong to the same group as melamine (cyanuric acid and ammelide), which, however, also have other chemical properties and besides also have a much lower nitrogen content.

Durch angestellte Versuche hat sich überraschenderweise herausgestellt, daß für die Stickstoffdüngung an Stelle der bisher üblichen Düngemittel mit Vorteil Melamin angewandt werden kann, da durch den dem Melamin eigenen hohen Stickstoffgehalt sich eine vorteilhafte Verwendungsmöglichkeit für diesen Zweck ergibt. Außerdem steht, da Melamin schwer wasserlöslich ist, ein langsam wirkendes stickstoffhaltiges Düngemittel damit zur Verfügung, das für bestimmte Bodenarten -und manche Kulturpflanzen vorzuziehen ist. Ausführungsbeispiele: Boden: Gewaschener Sand Gesamtertrag im Verhältnis zu dem Versuch Ertrag von ungedüngtem Sand Spinat I Hafer I keine Düngung des Sandes 1,00 1,00 Düngung g/1oo g Sand Melamin Na2HP04 .12 H20 K2S04 11 0,274 - - 6,54 3,00 111 0,0274 o,o6 0,0475 7,21 5,23 Man kann Melamin mit anderen Düngesalzen, wie z. B. Kalisalzen, Superphosphat, Triplephosphat, Kaliumnitrat und Calciumnitrat, in jedem Verhältnis mischen. Zum Beispiel: a) Melamin 15 0/0, Superphosphat 50 0%, Chlorkali 35 % ergeben einen Dünger mit 1o % Stickstoff, 12 % Phosphorsäure, 19,2 % Kali (K20); b) Melamin 22,5 0/0, Triplephosphat 40 0/0, Chlorkali 37,5 % ergeben einen Dünger mit 15 % Stickstoff, 18 % Phosphorsäure, 2o,8 % Kali (K20). Nachdem es gelungen ist, Melamin auf wirtschaftlicher Basis im großen herzustellen, so daß, mengenmäßig gesehen, allen Ansprüchen Genüge getan werden kann, ist Melamin auch wirtschaftlich vorteilhaft für Düngezwecke anzuwenden, da der Stickstoffgehalt des Melamins bekanntlich 66 0% beträgt.Through experiments it has surprisingly been found that melamine can advantageously be used for nitrogen fertilization in place of the previously customary fertilizers, since the high nitrogen content inherent in melamine results in an advantageous use for this purpose. In addition, since melamine is sparingly water-soluble, a slow-acting nitrogenous fertilizer is available, which is preferable for certain types of soil and some crops. Embodiments: Soil: washed sand Total return in proportion to the Try yield from unfertilized sand Spinach I oats I no fertilization of the sand 1.00 1.00 Fertilization g / 100 g sand Melamine Na2HP04 .12 H20 K2S04 11 0.274 - - 6.54 3.00 111 0.0274 o. O6 0.0475 7.2 1 5.23 You can mix melamine with other fertilizer salts, such as B. Potash salts, superphosphate, triple phosphate, potassium nitrate and calcium nitrate, mix in any ratio. For example: a) Melamine 15 0/0, superphosphate 50 0%, chlorine potash 35% result in a fertilizer with 10% nitrogen, 12% phosphoric acid, 19.2% potash (K20); b) Melamine 22.5 0/0, triple phosphate 40 0/0, chlorine potash 37.5% result in a fertilizer with 15% nitrogen, 18% phosphoric acid, 2o, 8% potash (K20). After it has been possible to produce melamine on an economical basis on a large scale, so that, in terms of quantity, all requirements can be met, melamine can also be used economically for fertilization purposes, since the nitrogen content of melamine is known to be 66 0%.

Außerdem eignet sich Melamin besonders gut auch deswegen für Düngezwecke, da das kristallisierte Salz nicht hygroskopisch ist und daher bei der Lagerung, beim Versand und beim Ausstreuen auf den Acker erhebliche Vorteile bietet. Melamin kann auch gemischt mit anderen Stoffen, z. B. phosphorsäure- oder kalihaltigen Düngemitteln und ebenfalls mit neutralen stickstoffhaltigen Düngemitteln (Ammonsulfat), verwendet werden, so daß derart mit Melamin hergestellte Mischdünger für viele Zwecke in ausreichendem Maße zur Verfügung stehen.In addition, melamine is particularly suitable for fertilization purposes, since the crystallized salt is not hygroscopic and therefore in storage, offers considerable advantages when it comes to shipping and spreading in the field. melamine can also be mixed with other substances, e.g. B. phosphoric acid or potassium fertilizers and also used with neutral nitrogenous fertilizers (ammonium sulfate) so that mixed fertilizers produced in this way with melamine are sufficient for many purposes Dimensions are available.
