Nhanganyaya
Iyo organic compound ine kemikari formula C6H5ClN2O3.
Zvakasikwa:
-Kuonekwa: Kuchena kusvika kuchiedza yellow solid
-Kunyungudika: 44-46°C
-Kubikira nzvimbo: 262°C
-Soluble in: doro uye ether, isinganyunguriki mumvura
Shandisa:
chinhu chakakosha chepakati, chinoshandiswa zvakanyanya mumunda we organic synthesis. Inogona kushandiswa kugadzira zvakasiyana-siyana biologically inoshanda makomisheni, senge mishonga, dhayi uye mishonga yezvipembenene.
Kugadzirira nzira:
Synthesis inogona kuitwa kuburikidza nematanho anotevera:
1. 2-Nitro-6-formylpyridine yakawanikwa nekuita 2-nitro-6-nitro-pyridine ne sulfuric acid.
2. Kuita kwe2-nitro-6-formylpyridine uye chloromethyl ether pasi pechiito che alkali inogadzirwa.
3. Kuchenesa uye crystallization matanho akaitwa kuti awane chigadzirwa chakachena.
Zvekuchengetedza
Chinhu chine njodzi chinogona kukonzeresa kusvotwa uye kusawirirana nemuviri nekufumurwa kana kufema. Paunenge uchishanda, pfeka matanho ekudzivirira akakodzera senge magirovhosi, magirazi uye zvipfeko zvekudzivirira, uye ona kuti kuvhiya kunoitwa munzvimbo ine mhepo inofefetera. Panguva yekuchengetedza nekubata, kusangana neakasimba oxidants uye zvinhu zvinopisa zvinopisa zvinofanirwa kudziviswa.
