2-Chloro-6-methoxy-3-nitropyridine (CAS# 38533-61-8)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R44 – Ingozi yokuqhuma uma kushisa uvalelwe R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. |
| I-WGK Germany | 3 |

Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali C6H5ClN2O3.
Imvelo:
-Ukubukeka: Okuqinile okumhlophe kuya kokuphuzi okukhanyayo
-Indawo yokuncibilika: 44-46°C
-Indawo yokubilisa: 262°C
-Incibilika ku: utshwala ne-ether, ayincibiliki emanzini
Sebenzisa:
iyingxenye ebalulekile, esetshenziswa kabanzi emkhakheni we-organic synthesis. Ingasetshenziselwa ukuhlanganisa inhlanganisela yezinto eziphilayo ezisebenzayo, njengezidakamizwa, odayi nezibulala-zinambuzane.
Indlela Yokulungiselela:
I-synthesis ingenziwa ngezinyathelo ezilandelayo:
1. I-2-Nitro-6-formylpyridine itholwe ngokuphendula i-2-nitro-6-nitro-pyridine nge-sulfuric acid.
2. Ukusabela kwe-2-nitro-6-formylpyridine ne-chloromethyl ether ngaphansi kwesenzo se-alkali kukhiqizwa.
3. Izinyathelo zokuhlanzwa kanye ne-crystallization zenziwe ukuze kutholwe umkhiqizo ohlanzekile.
Ulwazi Lokuphepha:
Into eyingozi engase ibangele ukucasuka nokungezwani komzimba ngokuchayeka noma ngokuhogela. Lapho usebenza, gqoka izindlela zokuzivikela ezifanele njengamagilavu, izibuko nezingubo zokuzivikela, futhi uqinisekise ukuthi umsebenzi wenziwa endaweni enomoya omuhle. Ngesikhathi sokugcina nokuphatha, ukuthintana nama-oxidants aqinile kanye nezinto ezivuthayo kufanele kugwenywe.
