Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Ubungozi Nokuphepha

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R25 – Kunobuthi uma ugwinywe
R40 – Ubufakazi obuncane bomphumela we-carcinogenic
Incazelo Yokuphepha 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.)
I-S37/39 – Gqoka amagilavu ​​afanelekile kanye nokuvikela iso/ubuso
I-S28A -
S36 – Gqoka izingubo ezifanele zokuzivikela.
S22 - Ungaphefumuli uthuli.

2-Amino-3-hydroxypyridine (CAS# 16867-03-1) isingeniso

2-Amino-3-hydroxypyridine. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

Ikhwalithi:
I-2-Amino-3-hydroxypyridine iyinhlanganisela yemvelo ebukeka njengekristalu emhlophe encibilika emanzini nezinye izincibilikisi eziphilayo.
Kuyisisekelo esiqinile esenza ama-asidi angathathi hlangothi futhi enze usawoti ohambisanayo. Ine-pH ephezulu futhi ivame ukusetshenziswa ekuphenduleni kokungathathi hlangothi.

Ukusetshenziswa: Ingasetshenziswa futhi ekulungiseni imikhiqizo ehlukahlukene yamakhemikhali efana nodayi, okokunamathela, nezithambisa.

Indlela:
Ukulungiswa kwe-2-amino-3-hydroxypyridine ngokuvamile kuqala ku-pyridine. Okokuqala, i-pyridine isabela ngegesi ye-ammonia ukuze yakhe i-2-aminopyridine. Khona-ke, phambi kwe-sodium hydroxide, ukusabela kwakhiwa ukwakha i-2-amino-3-hydroxypyridine.

Ulwazi Lokuphepha:
I-2-Amino-3-hydroxypyridine ingase ibe nomthelela ocasulayo emehlweni, esikhumbeni, nasohlelweni lokuphefumula. Ngesikhathi sokusebenzisa, sicela ugcine izinyathelo zokuzivikela ezifanele, njengokugqoka amagilavu, izibuko zokuphepha, njll. Sicela ugcine inhlanganisela ngendlela efanele, kude nomlilo nezinto ezivuthayo.
