Mawu Oyamba

(1S,2S) -1,2-diphenylethylenediamine, wotchedwanso (1S,2S) -1,2-diphenyl-1,2-ethanediamine, ndi organic amine pawiri. Zotsatirazi ndizofotokozera za katundu wake, ntchito, njira zokonzekera ndi chitetezo:

 

Ubwino:

 

Maonekedwe: ufa woyera wa crystalline

Kusungunuka: kusungunuka mu mowa, ethers ndi ketoni, osasungunuka m'madzi

Molecular formula: C14H16N2

Kulemera kwa maselo: 212.29 g/mol

 

Ntchito: (1S,2S) -1,2-diphenylethylenediamine ali osiyanasiyana ntchito m'mafakitale mankhwala ndi mankhwala:

 

Chiral ligand: Imakhala ngati chiral ligand ndipo ingagwiritsidwe ntchito pothandizira kaphatikizidwe ka asymmetric, makamaka popanga ma molekyulu a chiral organic.

Kaphatikizidwe ka utoto: Itha kugwiritsidwa ntchito ngati chapakatikati pakupanga utoto wachilengedwe.

Copper-nickel alloy coating: Itha kugwiritsidwanso ntchito ngati chowonjezera pokonzekera zokutira za aloyi zamkuwa-nickel.

 

Njira: (1S,2S) -1,2-diphenylethylenediamine ikhoza kupangidwa ndi njira zotsatirazi:

 

Sulfoxide chloride ndi phenylformaldehyde amawonjezeredwa ku ethylene glycol dimethyl ether kupanga diphenyl methanol.

Diphenylmethanol imachitidwa ndi triethylamine mu acetonitrile kupanga (1S,2S) -1,2-diphenylethylenediamine.

 

Chitetezo: Kugwiritsa ntchito (1S,2S) -1,2-diphenylethylenediamine kumakhala kotetezeka ngati kugwiridwa bwino ndikusungidwa. Komabe, monga mankhwala aliwonse, amafunikabe kutsatira njira zoyendetsera chitetezo cha labotale. Pewani kukhudza khungu ndi maso, ndipo pewani kutulutsa mpweya kapena kumeza. Magolovesi oteteza ndi magalasi oteteza ayenera kuvala akamagwiritsidwa ntchito, ndipo azigwiritsidwa ntchito pamalo omwe mpweya wabwino umatuluka. Ngati mwakumana ndi ngozi mwangozi kapena pokoka mpweya, pitani kuchipatala ndikudziwitsani za mankhwalawo.
