5-Bromo-2-chloro-3-nitropyridine (CAS# 67443-38-3)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R21/22 – Kuyingozi ukuthinta isikhumba futhi uma ugwinyiwe. R41 – Ingozi yokulimala okubi emehlweni R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba. R25 – Kunobuthi uma ugwinywe I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
I-2-Chloro-5-bromo-3-nitropyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
I-2-Chloro-5-bromo-3-nitropyridine iqinile emhlophe enephunga elibi. Inoncibilika okuphakathi futhi iyancibilika kuzincibilikisi zemvelo ezifana notshwala nama-hydrocarbon ane-chlorine.
Ukusetshenziswa: Ingasetshenziselwa ucwaningo kanye nezicelo zaselabhorethri.
Indlela:
Indlela yokulungiselela i-2-chloro-5-bromo-3-nitropyridine ingafinyelelwa ngezindlela ezihlukahlukene. Indlela evamile ukufeza ukushintshwa kwe-chlorine ne-bromine ngokungeza i-aluminium chloride noma amanye ama-sulfate ngaphansi kwezimo ze-alkaline ze-3-bromo-5-nitropyridine. Izindlela zokuhlanganisa ezinemininingwane zingadluliselwa ezincwadini zamakhemikhali noma kumanuwali ochwepheshe.
Ulwazi Lokuphepha:
Le nhlanganisela iyi-oxidizing eqinile ku-organic synthesis futhi idinga ukunakekelwa lapho igcinwa futhi iphathwa uma kwenzeka kuba nomlilo noma ukuqhuma.
Gwema ukuthinta izinto ezivuthayo, izinto ezinciphisayo nezinto ezivuthayo.
Izimpahla zokuzivikela ezifanele njengamagilavu elebhu, izibuko, nezingubo zokugqoka zidinga ukugqokwa ngesikhathi sokuphatha nokuphatha.
Gwema ukuhogela, ukumunca, noma ukuthinta isikhumba.
Kufanele igcinwe yomile lapho igcinwe futhi igweme ukuthintana nomswakama emoyeni.
Lapho ilahlwa, kufanele ilahlwe ngokuhambisana nemithetho yendawo futhi akufanele ilahlwe noma ikhishwe endaweni ezungezile.
