Ubungozi Nokuphepha

Izimpawu Eziyingozi Xi - Irritant
Amakhodi Engozi 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36 – Gqoka izingubo ezifanele zokuzivikela.
Ama-ID e-UN UN 3439 6.1/PG III

I-6-methylpyridine-2-carbonitrile (CAS# 1620-75-3) Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali i-C8H8N2. Okulandelayo yincazelo yobunjalo bayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:Imvelo:
-Ukubukeka: Iwuketshezi olungenambala ukuya kokuphuzi okuphaphathekile.
-Ukuminyana: mayelana ne-0.975g/cm³.
Iphuzu elibilayo: mayelana nama-64-66 degrees Celsius.
-Indawo yokuncibilika: Cishe -45 degrees Celsius.
-Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-methanol ne-dimethylformamide.Sebenzisa:
-futhi ingasetshenziswa njengama-reagents kanye nama-catalysts ku-organic synthesis.
-Isetshenziswa kabanzi emkhakheni we-chemistry yezokwelapha kanye nemithi ukuze kuhlanganiswe izidakamizwa.
-Ingasetshenziswa futhi njengesincibilikisi.

Indlela:
-ingalungiselelwa ukusabela kwe-pyridine nge-methyl hydrocyanate.
-Izimo zokusabela ngokuvamile zidinga ukwenziwa ngaphansi komkhathi wegesi engasebenzi, futhi i-catalyst, njenge-sodium cyanide iodide, iyengezwa.

Ulwazi Lokuphepha:
-okucasulayo emehlweni nasesikhumbeni, sicela ugweme ukuthintana ngqo.
-Uma usebenzisa, sicela usebenzise izinto zokuzivikela, njengezibuko zokuphepha namagilavu.
-Gcina endaweni epholile neyomile kude nomlilo nezinto ezivuthayo.
-Njengoba abanye abantu bengase bangezwani nakho, sicela wenze ukuhlolwa kokuphepha okufanele kanye nokuqeqeshwa kokusebenza elabhorethri ngaphambi kokusetshenziswa.
