Melemo

1. Bohloeki bo Phahameng: N, N'-Dicyclohexylcarbodiimide ea rona e entsoe ka mokhoa o nepahetseng ka ho fetisisa ho netefatsa bohloeki bo fetang 99%.Boemo bona ba bohloeki bo tiisa ts'ebetso e nepahetseng, e hlahisang litholoana tse tsitsitseng le tse tšepahalang ts'ebelisong ea hau.

2. Motsoako o babatsehang oa ho qhibiliha: DCC e na le ho qhibiliha ka mokhoa o babatsehang lihlahisoa tse fapa-fapaneng tsa manyolo, ho kenyelletsa le metsoako e tloaelehileng ea polar le e seng polar e kang ethanol, acetone, ether, le chloroform.Lintho tse ngata tsa eona tsa ho qhibiliha li etsa hore e tšoanele maemo a fapaneng a karabelo.

3. Moemeli ea sebetsang hantle oa ho kopanya: DCC e sebetsa e le moemeli ea sebetsang hantle ho kopanya li-peptide le ho lokisetsa metsoako e sa tšoaneng ea amido.Ts'ebetso ea carbodiimide e thusa karabelo ea condensation lipakeng tsa li-carboxylic acid le li-amine, e khothalletsang sebopeho se sebetsang sa amide bond.

4. Polokelo e tsitsitseng: N, N'-dicyclohexylcarbodiimide ea rona e phuthetsoe ka hloko le ho bolokoa ho netefatsa botsitso ba nako e telele ntle le ho bola ho bonahalang.Sena se eketsa bophelo ba sethala sa sehlahisoa, se u lumella ho se sebelisa ka botšepehi nako e telele.

5. Mefuta e mengata e fapaneng ea likopo: DCC e na le mefuta e mengata ea likopo lefapheng la meriana, k'hemistri, le lipatlisiso tsa thuto.Ke reagent ea bohlokoa ka har'a motsoako oa li-peptide, li-intermediate tsa lithethefatsi, li-polymers le limolek'hule tse ling tse rarahaneng tsa manyolo.

Khamphani ea rona, re beha boleng le khotsofalo ea bareki pele.N,N'-Dicyclohexylcarbodiimide ea rona e hlahisoa ka tlas'a tataiso e thata ea taolo ea boleng 'me e khomarela litekanyetso tsa machaba.Sepheo sa rona ke ho u fa lihlahisoa tse sa finyelleng feela empa li feta tebello ea hau.

Re fana ka N,N'-Dicyclohexylcarbodiimide ka boholo bo fapaneng ba ho paka ho fihlela litlhoko tse fapaneng.Ka kopo ikutloe u lokolohile ho ikopanya le rona bakeng sa lintlha tse ling kapa lipotso leha e le life tseo u ka bang le tsona.Re labalabela ho u thusa ho fumana tharollo e molemohali bakeng sa litlhoko tsa hau tsa lik'hemik'hale.
