Intshayelelo
I-4-carboxylphenylboronic acid yi-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi olukhuselekileyo lwe-4-carboxylphenylboronic acid:
Umgangatho:
- Imbonakalo: Ngokuqhelekileyo i-crystalline emhlophe okanye i-crystalline powder.
-Inyibilika: Inyibilika emanzini kunye nezinye izinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-acetone.
- Iipropati zeMichiza: I-Esterification, i-acylation kunye nezinye iimpendulo zingenzeka.
Sebenzisa:
- Njengombindi obalulekileyo kwi-organic synthesis, ingasetyenziselwa ukulungisa ezinye izinto eziphilayo.
Indlela:
- I-4-Carboxylbenzylboronic acid inokufumaneka ngokuphendula kwe-esterification ye-benzoic acid kunye ne-boric acid. Amanyathelo athile alandelayo: i-benzoic acid kunye ne-borate iyafudumala kwaye iphendule kwi-solvent ye-organic, kwaye ke imveliso ifunyenwe nge-crystallization.
Ulwazi ngoKhuseleko:
- I-4-carboxylphenylboronic acid ngokuqhelekileyo ithathwa njengento ekhuselekileyo, kodwa kusabalulekile ukunikela ingqalelo kwiindlela ezifanelekileyo zokuphatha ezikhuselekileyo.
- Xa usebenza, kuphephe ukudibana ngqo nolusu namehlo. Kwimeko yoqhagamshelwano, hlambulula ngokukhawuleza ngamanzi amaninzi.
- Xa ugcina, kufuneka igcinwe yomile kwaye kude namadangatye avulekileyo kunye nemithombo yobushushu.
