Nhanganyaya
2-Bromoisoniacin, inozivikanwawo se2-bromopyridine-4-carboxylic acid, inhengo yeorganic. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2-bromoisoniacinic acid:
Hunhu:
- Kuonekwa: 2-Bromoisoniacinic acid ichena kana isina-white crystalline yakasimba.
- Solubility: Inogona kunyungudutswa mune organic solvents senge mvura, ethanol, uye ether.
- Kemikari zvivakwa: Inogona kuita alkaline hydrolysis maitiro pasi pe alkaline mamiriro kuti igadzire inoenderana bromopyridine makomisheni.
Shandisa:
-Inogona zvakare kushandiswa sedhayi yepakati mukugadzirwa kwedhayi uye pigment.
Nzira:
- Nzira yakajairika yekugadzirira 2-bromoisoniacinic acid inowanikwa nekuita 2-picolinic acid ne thionyl bromide. Sanganisa 2-picolinic acid uye sulfoxide mumushonga wakakodzera uye wedzera imwe acidic catalyst. Zvadaro, thionyl bromide inowedzerwa zvishoma nezvishoma, uye maitiro anoitika. Mhinduro yekugadzirisa yakabatwa zvakanaka uye yakacheneswa kuti iwane 2-bromoisoniacinic acid chigadzirwa nekuchena kwepamusoro.
Ruzivo rwekuchengetedza: Chinhu chinogumbura chinogona kukonzera kusvotwa uye kusagadzikana mukubata neganda, maziso, kana nzira yekufema. Midziyo yekuzvidzivirira yakakodzera yakadai semagirovhosi, magirazi, nenhoo yekumeso inofanira kupfekwa kana ichishandiswa.
- Kana uchibata 2-bromoisoniacin, dzivisa kufemesa guruva rayo kana mhute. Mushure mekurapwa, nzvimbo dzakasvibiswa uye midziyo inofanira kunyatsocheneswa.
- Kuchengetedzwa kwakakodzera kwe2-bromoisoniacin, inofanira kuchengetwa munzvimbo yakaoma, inotonhorera uye ine mhepo yakanaka, kure nekupisa uye oxidants. Chengetedza zvakasiyana kubva kune zvinopisa, asidhi uye zvinodzikisa.
- Kana ukafemerwa netsaona, kuratidzwa, kana kunwa 2-bromoisoniacin, tsvaga kurapwa nekukasira uye uuye nemirairo kana label yechigadzirwa chiri mubvunzo.
