Nhanganyaya
4-carboxylphenylboronic asidhi ndeye organic compound. Iyi inotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye4-carboxylphenylboronic acid:
Hunhu:
- Kuonekwa: Kazhinji chena crystalline kana crystalline poda.
- Soluble: Soluble mumvura uye mamwe organic solvents senge ethanol uye acetone.
- Chemical zvivakwa: Esterification, acylation uye mamwe maitiro anogona kuitika.
Shandisa:
- Seyakakosha yepakati mune organic synthesis, inogona kushandiswa kugadzira mamwe organic komisheni.
Nzira:
- 4-Carboxylbenzylboronic acid inogona kuwanikwa ne esterification reaction ye benzoic acid ine boric acid. Matanho chaiwo ndeaya anotevera: benzoic acid neborate zvinodziyirwa uye zvinoitwa muorganic solvent, uyezve chigadzirwa chinowanikwa nekristalllization.
Zvekuchengetedza
- 4-carboxylphenylboronic acid inowanzoonekwa seyakachengetedzeka musanganiswa, asi zvichiri kukosha kutarisisa kune zvine musoro nzira dzekubata dzakachengeteka.
- Paunenge uchishanda, dzivisa kusangana zvakananga neganda nemeso. Kana wasangana, sukurudza pakarepo nemvura yakawanda.
- Paunenge uchichengeta, inofanira kuchengetwa yakaoma uye kure nemirazvo yakavhurika uye zvinopisa.
