Ubungozi Nokuphepha
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R22 – Iyingozi uma igwinywe R34 – Ibangela ukusha I-R11 – Ivutha Kakhulu |
| Incazelo Yokuphepha | S22 - Ungaphefumuli uthuli. I-S24/25 - Gwema ukuthintana nesikhumba namehlo. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. 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.) S16 – Zigcine kude nemithombo yokuthungela. |

I-Pyridine-4-boronic acid (i-CAS# 1692-15-5) isingeniso
I-4-Pyridine boronic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-4-pyridine boronic acid:
Ikhwalithi:
- Ukubukeka: I-4-pyridine boronic acid iyi-crystalline solid solid.
- Ukunyibilika: Kuncibilika emanzini nasezincibilikisini ezivamile ezifana notshwala, ama-ether, nama-ketone.
- Ukuzinza: I-4-Pyridine boronic acid izinzile ekamelweni lokushisa, kodwa ukubola kungase kwenzeke lapho kukhona izinga lokushisa eliphezulu, ukucindezela okukhulu, noma ama-oxidants aqinile.
Sebenzisa:
- I-Catalyst: I-4-pyridylboronic acid ingasetshenziswa njenge-catalyst ekuphenduleni kwe-organic synthesis, njengokusabela kokwakheka kwebhondi ye-CC kanye nokusabela kwe-oxidation.
- I-reagent yokuxhumanisa: Iqukethe ama-athomu e-boron, futhi i-4-pyridylboronic acid ingasetshenziswa njenge-reagent yokuxhumanisa i-ion yensimbi, idlala indima ebalulekile ku-catalysis nokunye ukusabela kwamakhemikhali.
Indlela:
- I-4-Pyridine boronic acid ingatholakala ngokuphendula i-4-pyridone nge-boric acid. Izimo ezithile zokusabela zizolungiswa ngokuya ngesimo sangempela.
Ulwazi Lokuphepha:
- I-4-Pyridine boronic acid iyinhlanganisela evamile yezinto eziphilayo, kodwa kusadingeka ukunakekela ukuphatha okuphephile. Izibuko zokuzivikela namagilavu kufanele kugqokwe uma kusetshenzwa.
- Gwema ukuthinta isikhumba kanye nokuhogela uthuli. Uma kwenzeka ukuthinta isikhumba ngengozi, hlambulula ngokushesha ngamanzi amaningi.
- Ngesikhathi sokusetshenziswa nokugcinwa, kufanele kuqashelwe ukugwema ukuthintana nama-oxidants aqinile nama-acids aqinile ukuze kugwenywe ukubangela ukusabela okuyingozi.
- Lapho ulahla imfucuza, kufanele ilahlwe ngokuphepha ngokuhambisana nemithetho yendawo.
