| titleOfInvention | Synthetic method of 2,3-dimethyl-2,3-dinitrobutane |
| abstract | The invention discloses a synthetic method of 2,3-dimethyl-2,3-dinitrobutane. The synthetic method comprises the following steps that 1, acetoxime, water, and catalyst modified titanium silicalite (TS)-1 are added into a reaction container at room temperature; 2, aqueous alkali and hydrogen peroxide are added dropwisely into the reaction system obtained by the previous step at a temperature of 60 to 90 DEG C with stirring; the pH of the reaction system is kept in a range of 8 to 10; and a mol ratio of hydrogen peroxide and acetoxime is in a range of 1 to (3: 1); 3, after dropwiseaddition, the mixture obtained from the step 2 undergoes a reaction at a temperature of 60 to 90 DEG C for 0 to 2 hours; 4, reaction products obtained from the step 3 is cooled to room temperature and then is subjected to a filtration or a centrifugation process thus modified TS-1 is separated from the cooled reaction product and mother liquor is obtained; the modified TS-1 is washed by acetone; washing liquid is collected; and the collected washing liquid is added into the mother liquor; and 5, the mother liquor containing the collected washing liquid is subjected to a distillation process at a temperature less than or equal to 80 DEG C so that acetone in the reaction system is removed; the mother liquor treated by the distillation process is cooled and filtrated; and filter residues are washed by water to form 2,3-dimethyl-2,3-dinitrobutane products. Raw materials adopted by the synthetic method have the advantages of good safety and low cost. 2,3-dimethyl-2,3-dinitrobutane synthesized by the synthetic method has the advantages of less impurities and high product quality. |
