2-Hydroxy-6-methyl-5-nitropyridine (CAS# 28489-45-4)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. 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. |
| Ikhodi ye-HS | 29333990 |
Isingeniso
I-2-Hydroxy-3-nitro-6-methylpyridine iyinhlanganisela ye-organic ene-chemical formula C7H7N2O3. Okulandelayo incazelo eningiliziwe yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-2-hydroxy-3-nitro-6-methylpyridine iyimpuphu ye-crystalline emhlophe kuya ephuzi ekhanyayo.
-I-Solubility: ukuncibilika kwayo emanzini kuphansi, kuncibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala, i-ether, i-ketone, njll.
-Iphuzu elincibilikayo: Indawo encibilikayo yalesi sithako icishe ibe ngu-194-198°C.
-Ukuzinza: kuzinzile uma kuqhathaniswa nezinga lokushisa legumbi, kodwa kufanele kugweme ukuchayeka endaweni yokukhanya kanye nezinga lokushisa eliphezulu.
Sebenzisa:
I-2-hydroxy-3-nitro-6-methylpyridine ivame ukusetshenziswa njengendawo ephakathi ku-organic synthesis futhi isetshenziselwa ukuhlanganiswa kwamanye ama-compounds.
-Ingasetshenziswa futhi ekulungiseni izinsiza zokucubungula irabha, izibulala-zinambuzane, imithi kanye nodayi neminye imikhakha.
Indlela:
-2-Hydroxy-3-nitro-6-methylpyridine ngokuvamile itholakala ngokuhlanganisa amakhemikhali. Indlela ethize ingatholakala ngokusabela i-3-methylpyridine nge-nitric acid ngokusabela kwe-nitrate, bese kuthi ngokunciphisa kanye nokusabela kwe-hydroxylation.
Ulwazi Lokuphepha:
-2-hydroxy-3-nitro-6-methylpyridine ikhemikhali enobuthi obuthile. Landela izinqubo zokuphepha zaselabhorethri ngesikhathi sokusebenza.
-Ukuxhumana noma ukuhogela lesi sakhi kungabangela ukucasuka nokulimala emzimbeni womuntu. Ukuthintana nesikhumba, ukuhogela umoya nokuwungenisa kufanele kugwenywe. Amagilavu okuvikela ochwepheshe, iso nempahla yokuphefumula kufanele kugqokwe ngesikhathi sokusetshenziswa.
-Uma uthinta isikhumba noma amehlo, hlambulula ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha ngokushesha ngangokunokwenzeka.
-Inhlanganisela kufanele igcinwe endaweni evalekile, eyomile, engenawo umoya, kude nomlilo kanye nama-oxidizing agents. Lapho ulahla imfucuza, landela imithetho yendawo yokuvikela imvelo.
