Taw qhia

(1S,2S)-1,2-diphenylethylenediamine, tseem hu ua (1S,2S)-1,2-diphenyl-1,2-ethanediamine, yog cov organic amine compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev npaj thiab kev nyab xeeb:

 

Zoo:

 

Cov tsos mob: Dawb crystalline hmoov

Solubility: soluble hauv cawv, ethers thiab ketones, insoluble hauv dej

Cov roj formula: C14H16N2

Molecular Luj: 212.29 g / mol

 

Siv: (1S,2S)-1,2-diphenylethylenediamine muaj ntau yam kev siv hauv kev lag luam tshuaj thiab tshuaj:

 

Chiral ligand: Nws ua raws li chiral ligand thiab tuaj yeem siv los ua kom cov asymmetric synthesis, tshwj xeeb tshaj yog rau cov synthesis ntawm chiral organic molecules.

Dye synthesis: Nws tuaj yeem siv los ua ib qho nruab nrab hauv kev sib xyaw ntawm cov organic dyes.

Copper-nickel alloy coatings: Nws kuj tseem siv tau los ua ib qho ntxiv hauv kev npaj ntawm tooj liab-nickel alloy coatings.

 

Txoj kev: (1S,2S)-1,2-diphenylethylenediamine tuaj yeem ua ke los ntawm cov kauj ruam hauv qab no:

 

Sulfoxide chloride thiab phenylformaldehyde ntxiv rau ethylene glycol dimethyl ether los ua diphenyl methanol.

Diphenylmethanol yog reacted nrog triethylamine hauv acetonitrile los tsim (1S,2S)-1,2-diphenylethylenediamine.

 

Kev nyab xeeb: Kev siv (1S,2S)-1,2-diphenylethylenediamine kuj muaj kev nyab xeeb thaum tuav thiab khaws cia zoo. Txawm li cas los xij, raws li txhua yam tshuaj, nws tseem yuav tsum tau ua raws li cov txheej txheem kev nyab xeeb ntawm kev ua haujlwm. Tsis txhob kov ntawm daim tawv nqaij thiab qhov muag, thiab tsis txhob nqus los yog nqos. Cov hnab looj tes tiv thaiv thiab tsom iav yuav tsum hnav thaum siv, thiab ua haujlwm hauv qhov chaw muaj cua zoo. Thaum raug xwm txheej los yog nqus tau pa, nrhiav kev kho mob thiab muab cov ntaub ntawv hais txog cov tshuaj.
