A kind of method for decomposing triazine ring residue and recovering methylhydrazine

ActiveCN110950775BSolve the difficult problems of industrializationAchieve recyclingHydrazine preparationPtru catalystBis-triazine
The invention discloses a method for decomposing and recovering methylhydrazine residues of triazine rings. Adding residues of triazine rings, water and copper salt into a reaction bottle, starting stirring, raising the temperature to 80-130°C for 2-5 hours, and following the reaction Carry out, extract distillate fraction from reaction bottle, distill distillate after distillate adds alkali, distill out composition and be the mixture of methylhydrazine and water. The present invention hydrolyzes the by-product triazine ring residue to recover methylhydrazine and is used for the synthesis of 2-methylthiosemicarbazide, further synthesizing the triazine ring, utilizing waste resources, solving the problem that the industrialization of the triazine ring residue is difficult to handle, and realizing The triazine ring residue is recycled to methylhydrazine and then to the triazine ring. No solvent is used, which eliminates the disadvantages of flammability, explosion and high cost of organic solvents; the raw material is only the triazine ring residue reacts with water, and the copper salt is used as a catalyst to recover and produce methylhydrazine, and hydrolyze the triazine ring residue into small Molecular salt, easy to handle, safe and environmentally friendly, low cost, suitable for industrial production.
