Description

Düngemittel Der Gegenstand des Patentes 917 o72 bezieht sich auf ein Düngemittel, welches aus Sulfitablauge, Harnstoff, Formaldehyd und aus einem sauren Katalysator, wie z. B. Superphosphat, besteht. Beim Mischen und Rühren der vorgenannten Stoffe miteinander setzt eine Kondensation ein, die so lange fortgesetzt wird, bis die Umwandlung in eine schneid- und stechbare Masse aus feinstverteilten Kunstharzteilchen erfolgt ist, die durch entsprechendes Zerkleinern in streufähige Form gebracht wird.Fertilizers The subject matter of patent 917 o72 relates to a Fertilizer made from sulphite waste liquor, urea, formaldehyde and an acidic Catalyst, such as B. superphosphate. When mixing and stirring the aforementioned Substances with each other set in a condensation, which continues until the conversion into a cut and puncture mass of finely divided synthetic resin particles has taken place, which is brought into spreadable form by appropriate crushing.

Der Gegenstand der vorliegenden Erfindung bezieht sich nun auf ein Düngemittel nach dem Hauptpatent, bei welchem in weiterer Ausbildung des Gegenstandes des Hauptpatentes an Stelle von Harnstoff auch beliebige andere kondensationsfähige NH.-Gruppen enthaltende Verbindungen, wie z. B. Melamin oder Sulfonamid, und an Stelle von Formaldehyd beliebige andere Aldehyde, wie z. B. Acetaldehyd oder Crotonaldehyd, verwendet werden. Bei Verwendung dieser Mischbestandteile wird ebenfalls aus der in der Technik in großen Mengen als Abfallprodukt anfallenden Sulfitablauge, die an sich schwierig zu verwerten und zu verarbeiten ist, in technisch einfacher, leicht durchzuführender Weise ein Düngemittel mit den gleich guten Eigenschaften und Vorteilen erhalten wie desjenigen nach dem Hauptpatent. Auch die Vorteile des Verfahrens nach dem Hauptpatent werden in gleicher Weise bei dem Gegenstand der vorliegenden Erfindung erreicht. Außerdem werden die Möglichkeiten, aus Sulfitablauge für die landwirtschaftliche Praxis brauchbare, gehaltreiche Düngemittel zu gewinnen , gemäß der vorliegenden Erfindung erheblich erweitert.The subject matter of the present invention relates to a fertilizer according to the main patent, in which, in a further development of the subject matter of the main patent, instead of urea, any other compounds containing condensable NH groups, such as, for. B. melamine or sulfonamide, and any other aldehydes in place of formaldehyde, such as. B. acetaldehyde or crotonaldehyde can be used. When using these mixed components, a fertilizer with the same good properties and advantages as the one after is obtained from the sulphite waste liquor, which is produced in large quantities as a waste product and is difficult to utilize and process the main patent. The advantages of the method according to the main patent are achieved in the same way with the subject matter of the present invention. In addition, the opportunities to gain useful, content-rich fertilizer from sulfite liquor for agricultural practice, greatly expanded according to the present invention.

Ausführungsbeispiele 75o Gewichtsteile Sulfitablauge (32' B6), 117 Gewichtsteile Acetaldehyd und --oo Gewichtsteile Harnstoff werden z. B. miteinander bis zur völligen Lösung des letzteren gemischt und dann 2oo Gewichtsteile Superphosphat unter weiterem Rühren zugesetzt.Embodiments 75o parts by weight of sulphite waste liquor (32 ' B6), 117 parts by weight of acetaldehyde and --oo parts by weight of urea are z. B. mixed with each other until the latter is completely dissolved and then 200 parts by weight of superphosphate are added with continued stirring.

An Stelle der drei erstgenannten Stoffe können z. B. auch 75o Gewichtsteile Sulfitablauge (32,' B6), 33o Gewichtsteile Formaldehyd (35"/,ig) und 28o Gewichtsteile Melamin oder 75o Gewichtsteile Sulfitablauge (32'B6), 117 Gewichtsteile Acetaldehyd und --8o Gewichtsteile Melamin auf die gleiche Weise miteinander vermischt und danach 2oo Gewichtsteile Superphos-.phat zugesetzt werden,Instead of the first three substances, z. B. also 75o parts by weight of sulphite waste liquor (32, ' B6), 33o parts by weight of formaldehyde (35 "/, ig) and 28o parts by weight of melamine or 75o parts by weight of sulphite waste liquor (32'B6), 117 parts by weight of acetaldehyde and -8o parts by weight of melamine in the same way mixed with one another and then 2oo parts by weight of Superphos-.phat are added,
