Selelekela
4-carboxylphenylboronic acid ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa, tšebeliso, mekhoa ea ho lokisa le tlhaiso-leseling ea polokeho ea 4-carboxylphenylboronic acid:
Boleng:
- Ponahalo: Hangata phofo e tšoeu ea kristale kapa kristale.
- E qhibiliha: E qhibiliha ka metsing le linthong tse ling tsa tlhaho tse kang ethanol le acetone.
- Thepa ea lik'hemik'hale: Esterification, acylation le liketso tse ling li ka etsahala.
Sebelisa:
- Joalo ka karolo ea bohlokoa lipakeng tsa organic synthesis, e ka sebelisoa ho lokisa metsoako e meng ea manyolo.
Mokhoa:
- 4-Carboxylbenzylboronic acid e ka fumanoa ka karabelo ea esterification ea asiti ea benzoic ka asiti ea boric. Mehato e tobileng ke e latelang: benzoic acid le borate li futhumatsoa 'me li itšoara ka har'a motsoako oa lintho tse phelang, ebe sehlahisoa se fumanoa ka crystallization.
Lintlha tsa Tšireletseho:
- 4-carboxylphenylboronic acid ka kakaretso e nkoa e le motsoako o batlang o sireletsehile, empa ho ntse ho le bohlokoa ho ela hloko mekhoa e utloahalang ea ho tšoara e sireletsehileng.
- Ha o sebetsa, qoba ho kopana ka ho toba le letlalo le mahlo. Haeba u kopana, hlatsoa hang-hang ka metsi a mangata.
- Ha e bolokoa, e lokela ho bolokoa e omme le hole le malakabe a bulehileng le mehloli ea mocheso.
