2-Hydroxy-4-methyl-5-nitropyridine (CAS# 21901-41-7)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. 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. S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C7H7N2O3.
Imvelo:
iqinile enombala ophuzi ophuzi kuya kophuzi. Incibilika kakhulu kuzincibilikisi futhi ayincibiliki kalula emanzini. Inezinga elithile lokuvutha, futhi lapho ishiswa noma ihlangabezana nelangabi elivulekile lizokhiqiza ama-nitrogen oxides anobuthi (NOx).
Sebenzisa:
Ivame ukusetshenziswa ku-organic synthesis njengento ebalulekile ephakathi. Ingasetshenziswa ekuhlanganiseni ama-pyridine compounds, njengezibulala-zinambuzane, izidakamizwa kanye namadayi. Ngaphezu kwalokho, ingasetshenziswa futhi njenge-ligand yezakhiwo zensimbi.
Indlela:
Ngokuvamile kulungiselelwe ukusabela kwe-4-methyl-2-nitropyridine ne-sodium hydroxide. Ukusabela kuvame ukwenziwa ku-solvent ephilayo futhi umkhiqizo ungatholakala.
Ulwazi Lokuphepha:
Kuyingozi emzimbeni womuntu. Ukuthinta isikhumba kungase kubangele ukungezwani komzimba, futhi ukuhogela uthuli noma umhwamuko kufanele kugwenywe. Lapho uphatha, kufanele kuthathwe izinyathelo zokuzivikela ezifanele, njengokugqoka amagilavu, izibuko nezingubo zokuzivikela. Lapho isetshenziswa noma igcinwa, kufanele ibe kude nomlilo kanye ne-oxidant. Endabeni yokuvuza ngengozi, shiya indawo evuzayo ngokushesha futhi uthathe izinyathelo ezifanele zokuhlanza.
