Mawu Oyamba
4-carboxylphenylboronic acid ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chitetezo cha 4-carboxylphenylboronic acid:
Ubwino:
- Maonekedwe: Nthawi zambiri woyera crystalline kapena crystalline ufa.
- Zosungunuka: Zosungunuka m'madzi ndi zosungunulira zina monga ethanol ndi acetone.
- Chemical katundu: Esterification, acylation ndi zina zimachitika.
Gwiritsani ntchito:
- Monga gawo lofunikira pakuphatikizika kwa organic, itha kugwiritsidwa ntchito pokonzekera zinthu zina zakuthupi.
Njira:
- 4-Carboxylbenzylboronic asidi angapezeke ndi esterification anachita benzoic asidi ndi asidi boric. Masitepe enieni ndi awa: benzoic acid ndi borate zimatenthedwa ndikuchitapo kanthu mu zosungunulira za organic, ndiyeno mankhwalawa amapezedwa ndi crystallization.
Zambiri Zachitetezo:
- 4-carboxylphenylboronic acid nthawi zambiri imatengedwa kuti ndi yotetezeka, komabe ndikofunikira kulabadira njira zotetezeka zogwirira ntchito.
- Mukamachita opaleshoni, pewani kukhudza khungu ndi maso. Mukakhudza, muzimutsuka nthawi yomweyo ndi madzi ambiri.
- Posunga, ikuyenera kukhala yowuma komanso yotalikirana ndi malawi otseguka komanso kutentha.
