| titleOfInvention | A kind of preparation method of 1,4,5,8-tetramino naphthalene stannic chloride hydrochlorate |
| abstract | A kind of Isosorbide-5-Nitrae, the preparation method of 5,8 tetramino naphthalene stannic chloride hydrochlorates, relate to the preparation method of a kind of hydrochlorate.The present invention is to solve that existing method prepares Isosorbide-5-Nitrae, the by-product that 5,8 tetramino naphthalene stannic chloride hydrochlorates exist is many, and cost is high, and productivity is low, and post processing is loaded down with trivial details, it is difficult to the technical problem of industrial amplification production.The method comprise the steps that one, prepare highly purified 1,4,5,8 tetranitro-naphthalenes；Two, highly purified 1,4,5,8 tetramino naphthalene stannic chloride hydrochlorates are prepared.The present invention successfully prepares the highly purified Isosorbide-5-Nitrae that routine is difficult to synthesize, and 5,8 tetranitro-naphthalenes, and by the addition of catalyst aid, use stannous chloride and concentrated hydrochloric acid height yield to be prepared for Isosorbide-5-Nitrae, 5,8 tetramino naphthalene stannic chloride hydrochlorates, simplify operating procedure, and raw material selected by the present invention is cheap and easy to get, yield is high, low cost, and environmental friendliness, applicable industry are amplified.The present invention is applied to the preparation field of organic intermediate. |
