2-Amino-3-methyl-5-nitropyridine (CAS# 18344-51-9) chiyambi
2-Amino-3-methyl-5-nitropyridine, yomwe imadziwikanso kuti methylnitropyridine. Zotsatirazi ndikuyambitsa zina mwazinthu, ntchito, njira zokonzekera, ndi chidziwitso chachitetezo:
Ubwino:
1. Maonekedwe: 2-amino-3-methyl-5-nitropyridine ndi woyera wonyezimira wachikasu kristalo kapena crystalline ufa.
3. Kusungunuka: Kusungunuka m'madzi, koma kusungunuka muzinthu za acidic.
Gwiritsani ntchito:
1. Chemical reagent: 2-amino-3-methyl-5-nitropyridine ingagwiritsidwe ntchito ngati chitsulo chosakanikirana ndi chitsulo, chothandizira kupanga organic synthesis ndi mankhwala ofunikira apakati.
2. Zida zophulika ndi mfuti: Chigawochi chimakhala ndi kuphulika kwakukulu, ndipo chitha kugwiritsidwa ntchito pokonzekera zophulika ndi mfuti.
3. Mankhwala ophera tizilombo: 2-amino-3-methyl-5-nitropyridine angagwiritsidwe ntchito ngati mankhwala ophera tizilombo ndi herbicide.
Njira:
2-Amino-3-methyl-5-nitropyridine ikhoza kukonzedwa ndi:
1. Imapezedwa ndi zomwe ma molekyulu a pirani ndi asidi wa nitric pansi pa acidic.
2. Amapezedwa pochita ndi formaldehyde pamene oxidizing ammonium nitrite pogwiritsa ntchito aminopyrrole.
Zambiri Zachitetezo:
1. 2-amino-3-methyl-5-nitropyridine ili ndi kuphulika kwakukulu ndipo ndi chinthu choyaka moto, choncho iyenera kusungidwa kutali ndi moto wotseguka ndi magwero a kutentha.
2. Fumbi limene limakhudzana ndi khungu ndi kutulutsa mankhwalawo lingayambitse mkwiyo, choncho pewani kukhudzana ndi khungu ndi kupuma fumbi panthawi yogwira ntchito, ndipo valani magolovesi otetezera ndi masks.
3. Njira zoyendetsera ntchito zotetezeka ziyenera kutsatiridwa pogwira chinthu ndikusungidwa bwino kuti tipewe ngozi ndi kuwonongeka. Ayenera kusindikizidwa ndi kusungidwa pamene sakugwiritsidwa ntchito.
