| 41 | VERFAHREN ZUR HERSTELLUNG VON CALCIUMCYANAMID AUS HARNSTOFF | EP95910546.1 | 1995-03-02 | EP0749401B1 | 1997-11-12 | WEBER, Günter; GRAEFE, Jürgen; KLIMA, Hubertus; WOLFERSTETTER, Johann |
| The invention concerns a process for preparing calcium cyanamide by reacting urea with an oxygenous calcium compound in at least two steps: a) in a first step the reaction components are reacted by condensation and/or circulation or by applying them to a hot surface at temperatures of between 120 and 500 °C until a solid forms; and b) the resultant solid reaction mixture is then calcined at temperatures of between 600 and 900 °C. In this way high yields and charges of calcium cyanamide can be obtained without necessitating complicated reprocessing of the reaction product after the first or second step. | ||||||

| Calcium cyanamide compositions and methods for their use are disclosed. The compositions and methods stabilize active ionic compositions comprising calcium cyanamide and enhance the effectiveness of calcium cyanamide alone or synergistically in combination with nitrogen containing materials such as urea and organics, for example, manures. The compositions and methods also facilitate controllable site directed delivery of the contents of the stabilized compositions. The compositions and methods are effective for fertilizing, soil amending, metal stabilizing and odor and organism inhibition. The compositions are stable, easily calibrated, and non-clogging for spray delivery to target sites. | ||||||

| Processes and structures for using calcium cyanamide fertilizer in a manner to greatly enhance its most effective oil treatment form prior to its application. Dry, dusty granules and fines of calcium cyanamide are placed directly into tanks of liquid for transformation or within biodegradable bags through which water can freely flow. The bags are submerged in a tank of water. The insoluble calcium oxide and carbon components thereof remain as solid residuals within the bags. Hydrolysis occurs and the solution is biocidal and ready for immediate application. The solution can be sprayed or irrigated onto a targeted soil area with conventional dispersal equipment. The remaining non-dissolved material in the bags can be dispersed on and into the plant crop soil. Additives of other fertilizers into the above solution can be used to enhance effectiveness. When the calcium cyanamide is placed directly into the liquid, the mixture will become slurry-like. | ||||||

| Processes and structures for using calcium cyanamide fertilizer in a manner to greatly enhance its most effective soil treatment form prior to its application. Calcium cyanamide transformation structures have both fertilizing and pesticidal qualities; however, it is difficult to obtain uniform, efficient effectiveness from dry calcium cyanamide's liquid transformation structures. In the process of this invention, dry, dusty granules and fines of calcium cyanamide are placed directly into tanks of liquid for transformation or within biodegradable bags through which water can freely flow. The bags are submerged in a tank of water. The insoluble calcium and carbon components thereof remain as solid residuals within the bags. Hydrolysis occurs and the solution is biocidal and ready for immediate application. The solution can be sprayed or irrigated onto a targeted soil area with conventional dispersal equipment. The remaining non-dissolved material in the bags can be dispersed on and into the plant crop soil. Additives of other fertilizers into the above solution can be used to enhance effectiveness. When the calcium cyanamide is placed directly into the liquid, the mixture will become slurry-like. In the processes herein, when the solids of calcium cyanamide are not isolated during hydrolysis, the slurry mixture is utilized in recent modern specialized solids fertilizer suspension dispersed equipment having sufficient agitation to keep the solids in suspension. | ||||||
