Omaka bomkhiqizo

Ubungozi Nokuphepha

Amakhodi Engozi 34 - Ibangela ukusha
Incazelo Yokuphepha S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)

 

 

2-FLUORO-3-NITRO-4-PICOLINE (CAS# 19346-43-1) Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali C6H5FN2O2. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:Imvelo:
iqinile elingenambala ukuya kokuphuzi ngokuphaphathekile. Iyazinzile ezingeni lokushisa elivamile futhi ayincibiliki emanzini, kodwa incibilika kuzincibilikisi eziphilayo njenge-ethanol ne-dimethylformamide. Kuyinhlanganisela ye-alkali ebuthakathaka.

Sebenzisa:
Isetshenziswa kakhulu njengengxenye ebalulekile ekuhlanganiseni kwe-organic. Ingasetshenziselwa ukulungiselela izinhlobonhlobo zezinhlanganisela ezifana nezidakamizwa, odayi nezibulala-zinambuzane. Ivame ukusetshenziswa njengempahla eluhlaza yama-antibiotics, izidakamizwa ezilwa nomdlavuza kanye nezibulala-zinambuzane emkhakheni wezokwelapha.

Indlela:
Ukulungiswa kwe-mercury kungafinyelelwa ngezindlela ezihlukahlukene. Indlela evamile iwukusabela i-4-picoline ne-hydrogen fluoride noma i-sodium fluoride bese kuba nge-nitric acid ukuze uthole umkhiqizo owufunayo.

Ulwazi Lokuphepha:
Ingokwezinhlanganisela eziphilayo futhi inobuthi obuthile. Ngenqubo yokusebenza nokusetshenziswa, kuyadingeka ukuthatha izinyathelo zokuzivikela ezanele, okuhlanganisa ukugqoka amagilavu, izibuko, izingubo zokuzivikela, njll. Gwema ukuhogela, ukungenwa kanye nokuxhumana nesikhumba. Ngesikhathi sokugcina nokuphatha, ukunakekelwa kufanele kuthathwe ukugwema umlilo futhi ugweme ukuthintana nama-oxidants, ama-acids aqinile nezinye izinto. Lapho kulahlwa imfucuza, kufanele ilahlwe ngokuhambisana nemithethonqubo ehambisanayo ukuze kuvinjelwe ukungcoliswa kwemvelo.
