4-Formylphenylboronic acid (CAS# 87199-17-5)
| Amakhodi Engozi | R34 – Ibangela ukusha 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. 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 S36 – Gqoka izingubo ezifanele zokuzivikela. |

Isingeniso
I-4-carboxylphenylboronic acid iyinhlanganisela ephilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-4-carboxylphenylboronic acid:
Ikhwalithi:
- Ukubukeka: Imvamisa i-crystalline emhlophe noma i-crystalline powder.
- Iyancibilika: Incibilika emanzini nakwezinye izincibilikisi eziphilayo njenge-ethanol ne-acetone.
- Izakhiwo zamakhemikhali: I-Esterification, i-acylation nokunye ukusabela kungenzeka.
Sebenzisa:
- Njengengxenye ebalulekile ku-organic synthesis, ingasetshenziswa ukulungisa ezinye izinhlanganisela eziphilayo.
Indlela:
- I-4-Carboxylbenzylboronic acid ingatholwa ngokusabela kwe-esterification ye-benzoic acid ne-boric acid. Izinyathelo eziqondile zimi kanje: i-benzoic acid ne-borate ziyashiswa futhi zisabela ku-solvent ephilayo, bese umkhiqizo utholwa nge-crystallization.
Ulwazi Lokuphepha:
- I-4-carboxylphenylboronic acid ngokuvamile ibhekwa njengenhlanganisela ephephile, kodwa kusabalulekile ukunaka izindlela zokuphatha eziphephile ezinengqondo.
- Uma usebenza, gwema ukuthintana ngqo nesikhumba namehlo. Uma kwenzeka ukuthintana, hlambulula ngokushesha ngamanzi amaningi.
- Lapho uyigcina, kufanele igcinwe yomile futhi ikude namalangabi avulekile nemithombo yokushisa.
