Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha S22 - Ungaphefumuli uthuli.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.

 

Isingeniso

I-4-Iodo-3-nitrobenzoic acid iyinhlanganisela ye-organic enefomula yamakhemikhali i-C7H4INO4. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

 

Imvelo:

-Ukubukeka: I-4-Iodo-3-nitrobenzoic acid iyimpuphu ye-crystalline ephuzi.

-Indawo yokuncibilika: cishe ku-230°C.

-I-Solubility: Incibilika ku-ethanol, ether ne-chloroform, ayincibiliki emanzini.

 

Sebenzisa:

- I-4-Iodo-3-nitrobenzoic acid isetshenziswa kakhulu njengendawo ephakathi ku-organic synthesis.

-Kuyinto ebalulekile yokusetshenziswa kwezidakamizwa kanye nezibulala-zinambuzane.

-Ingase futhi isetshenziselwe ukuhlanganiswa kwezingqimba ezikhipha ukukhanya kumadivayisi we-organic electroluminescent (OLED).

 

Indlela Yokulungiselela:

Kunezindlela eziningi zokulungiselela i-4-Iodo-3-nitrobenzoic acid, enye yazo evame ukusetshenziswa ukuthola nge-nitrate ye-iodobenzoic acid. Izinyathelo zokulungiselela zimi kanje:

1. chitha i-iodobenzoic acid ku-nitric acid egxilile.

2. Faka kancane kancane i-sulfuric acid egxilile ekushiseni okuphansi bese uvuselela ukusabela.

3. Ngemuva kokuthi ukusabela kwenziwa isikhathi esithile, umkhiqizo kwisisombululo sokuphendula uhlukaniswa ngokuhlunga noma i-crystallization.

4. I-4-Iodo-3-nitrobenzoic acid ekugcineni yahlanzwa ngokugeza nge-solvent efanelekile kanye ne-crystallization.

 

Ulwazi Lokuphepha:

I-4-Iodo-3-nitrobenzoic acid iyinhlanganisela yezinto eziphilayo. Kufanele kuthathwe izinyathelo zokuzivikela uma uyisebenzisa, njengokugqoka amagilavu ​​nezibuko zokuvikela amehlo.

-Inhlanganisela iyagqwala ngezinga elithile, gwema ukuthintana kwesikhumba nokuhogela.

-Ngesikhathi sokusebenza, qaphela ukugwema ukuthintana nama-oxidants aqinile kanye nama-ejenti anciphisayo ukuze ugweme ukusabela okuyingozi.

-Ngesikhathi sokuyigcina, kufanele igcinwe endaweni epholile, eyomile, enomoya omuhle, ehlukaniswe nezinto ezivuthayo kanye nezinto ezivuthayo.

-Uma kwenzeka ukuthintana, hlambulula ngokushesha indawo ethintekile ngamanzi amaningi futhi ufune usizo lwezokwelapha.
