Nhanganyaya
Iro organic compound ine kemikari formula yeC, H, BrN, O. Inotevera sumo yezvimwe zvayo, kushandiswa, nzira uye ruzivo rwekuchengetedza:
Zvakasikwa:
-Kuonekwa: isina ruvara kune yero crystal kana fomu yehupfu.
-Solubility: Inogona kunyungudutswa mune organic solvents, senge ethanol, dimethyl sulfoxide uye chloroform, asi isinganyungudika mumvura.
Shandisa:
-Synthetic chemistry: Iyo inowanzoshandiswa ligand, iyo inogona kuumba ma complexes ane shanduko yesimbi uye inoshandiswa se catalysts mu organic synthesis.
-Kugadzira mishonga yezvipembenene: Inogona zvakare kushandiswa seyepakati kune mamwe mishonga yezvipembenene.
Nzira:
Iyo nzira yekugadzirira inogona kuitwa nematanho anotevera:
1. Kutanga, lutidine inonyungudutswa mu dimethyl sulfoxide.
2. Pakutonhora kwakadzika, zvishoma nezvishoma wedzera nitric acid uchichengeta maitiro ekushisa ari pasi pe0 degrees Celsius.
3. Zvishoma nezvishoma wedzera bromoethane Dropwise mugadziriro yekugadzirisa, ramba uchichengetedza kutonhora kwakadzika, uye simbisa kusvika pakuguma kwekuita.
4. Pakupedzisira, kusanganiswa kwekuita kunonatswa, kushambidzwa, kusvibiswa uye kuomeswa kuti uwane calcium.
Zvekuchengetedza
Inogona kukonzera dzimwe njodzi kumuviri wemunhu uye nharaunda, saka iwe unofanirwa kutarisisa kune hutano nekuchengetedza nyaya kana uchishandisa nekubata. Hezvino zvimwe zvekuchengetedza:
-Pfeka midziyo yekudzivirira yakakodzera semagirovhosi, magirazi nembatya dzekudzivirira kana uchinge washandiswa.
-Dzivisa kufema guruva rayo uye kubata neganda. Kana wasangana netsaona, kurumidza kugezesa nzvimbo yakakanganisika nemvura yakawanda uye tsvaga rubatsiro kuna chiremba.
-Gara kure nekupisa uye kunobva moto panguva yekuchengetera nekubata, uye chengetedza mhepo yakanaka.
-Dzivisa kusangana zvakananga nemaoxidants, acids, alkalis uye zvimwe zvinhu kuti udzivise kuita zvine njodzi.
Ndapota cherechedza kuti ruzivo rwakapiwa pano nderwereferensi chete. Paunenge uchishandisa uye kubata makemikari mukuita, iva nechokwadi chekutaura kune akakodzera mabhuku uye kubata mitemo yekuchengetedza, uye tevera nhungamiro yehunyanzvi.
