I-2-Amino-5-nitropyridine CAS 4214-76-0

I-2-Amino-5-nitropyridine CAS 4214-76-0 itholakala ku-nitrate ye-2-aminopyridine. Ezingeni lokushisa elingu-50 °C, i-2-aminopyridine yanezelwa ku-concentrated sulfuric acid, kwase kwengezwa i-nitric acid evuthayo, futhi izinga lokushisa alidluli ku-50 °C. Fukamela ku-45°C amahora angu-2, bese ugoqa ekamelweni lokushisa amahora angu-4. Isixazululo sokusabela sithelwa eqhweni elichotshoziwe, futhi i-pH yalungiswa yaba ngu-6 ngokungeza amanzi e-ammonia ngaphansi kuka-5 ° C, futhi amakristalu ancipha. Hlunga futhi wome. Ukuvuselela kabusha ngamanzi ukuze uthole ama-platelet aphuzi aphuzi, khiqiza ama-75%

Incazelo Yomkhiqizo

I-Believe Chemical ingumkhiqizi ohamba phambili wase-China 2-Amino-5-nitropyridine CAS 4214-76-0, umphakeli kanye nomkhiqizi. Ukunamathela ekuphishekeleni ikhwalithi ephelele yemikhiqizo, ukuze i-2-Amino-5-nitropyridine CAS 4214-76-0 yethu yaneliswe amakhasimende amaningi. Shandong Kholwa

Sisebenza kahle ngezinzuzo zemikhiqizo yamakhemikhali emkhakheni. Imikhiqizo yethu ithunyelwa eYurophu, e-United States, Japan, South Korea, Southeast Asia nakwamanye amazwe nezifunda. Ngomhlahlandlela wesayensi nobuchwepheshe, ukwethembeka njengesisekelo, ikhwalithi njengempilo, nokuthembela kumqondo webhizinisi wokuqamba nokuthuthuka, sithemba ngobuqotho ukusungula ukuhwebelana nokubambisana okubanzi namakhasimende asekhaya nawakwamanye amazwe ukuze sakhe ukuchuma!
