Sebenzisa Izicelo zisetshenziswa kakhulu ekuhlanganiseni kwe-asymmetric kanye nesixazululo se-optical, njenge-asymmetric hydroxylation reaction of olefins, asymmetric aldol condensation reaction, asymmetric Diels-Alder reaction, asymmetric allylation reaction of carbonyl, synthesis of Allylene alcohols optically active and propynyl alcohols epoxinsation ngaphandle kwamaqembu asebenzayo, ukulungiswa kwe i-binaphthol, njll.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izimpawu Eziyingozi C – Iyabola
Amakhodi Engozi R34 – Ibangela ukusha
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)

Isingeniso

(1S,2S)-1,2-diphenylethylenediamine, eyaziwa nangokuthi (1S,2S)-1,2-diphenyl-1,2-ethanediamine, inhlanganisela ye-amine ephilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa, izindlela zokulungiselela nokuphepha:

 

Ikhwalithi:

 

Ukubukeka: I-crystalline powder emhlophe

Ukunyibilika: kuncibilika otshwaleni, ethers namaketone, okungancibiliki emanzini

I-Molecular Formula: C14H16N2

Isisindo sengqamuzana: 212.29 g/mol

 

Isebenzisa: (1S,2S)-1,2-diphenylethylenediamine inezinhlobonhlobo zezicelo ezimbonini zamakhemikhali nezemithi:

 

I-Chiral ligand: Isebenza njenge-chiral ligand futhi ingasetshenziselwa ukugqugquzela ukuhlanganiswa kwe-asymmetric, ikakhulukazi ekuhlanganiseni kwama-molecule e-chiral organic.

Ukwakheka kodayi: Kungasetshenziswa njengendawo ephakathi ekuhlanganiseni odayi bezinto eziphilayo.

I-copper-nickel alloy coating: Ingasetshenziswa futhi njengesengezo ekulungiseleleni i-copper-nickel alloy coatings.

 

Indlela: (1S,2S)-1,2-diphenylethylenediamine ingahlanganiswa ngezinyathelo ezilandelayo:

 

I-Sulfoxide chloride ne-phenylformaldehyde yengezwa ku-ethylene glycol dimethyl ether ukuze kwakhiwe i-diphenyl methanol.

I-Diphenylmethanol isabela nge-triethylamine ku-acetonitrile ukuze ikhiqize (1S,2S) -1,2-diphenylethylenediamine.

 

Ukuphepha: Ukusetshenziswa kwe-(1S,2S)-1,2-diphenylethylenediamine kuphephile uma kuphethwe futhi kugcinwe kahle. Kodwa-ke, njenganoma yiliphi ikhemikhali, kusadingeka ukuthi ilandele izinqubo ezifanele zokusebenza zokuphepha zaselabhorethri. Gwema ukuthinta isikhumba namehlo, futhi gwema ukuhogela umoya noma ukugwinya. Amagilavu ​​okuzivikela kanye nezibuko kufanele kugqokwe lapho kusetshenziswa, futhi kusetshenziswe endaweni enomoya omuhle. Esimeni sokuchayeka ngengozi noma uhogele umoya, funa usizo lwezokwelapha futhi unikeze ulwazi mayelana nekhemikhali.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
