| titleOfInvention | Preparation method of guanylurea nitrate copper salt complex |
| abstract | A preparation method of a guanylurea nitrate copper salt complex comprises the following steps of (by mass percent) dicyandiamide, solvent =10% -20%: preparing a solution by 90-80 percent, and heating the solution until the solution is transparent; putting copper nitrate with the dicyandiamide amount of 1.4-1.5 mass ratio into dicyandiamide solution at 50-70 ℃, and adding the copper nitrate within 30 min-1 h; after the feeding is finished, heating to 80-95 ℃, and continuing to react for 2-5 h; stopping the reaction, and cooling until a large amount of products are separated out; filtering, washing and drying at 30-80 ℃ to obtain the CuGUN product. Compared with the prior art, the method provided by the invention adopts excessive copper nitrate with crystal water as a reactant, and can be completely removed in the subsequent washing process. |
