Expressed lej: enantiomeric ntau dhau =% ntawm cov enantiomer loj - % ntawm me me enantiomer. Piv txwv li: Ib qho kev sib xyaw ua ke ntawm 86% R enantiomer thiab 14% S enantiomer muaj 86% - 14%=72% ee. Ib yam khoom uas yog ib leeg, ntshiab enantiomer (piv txwv li, muaj 100% ee) hu ua homochiral lossis optically ntshiab.
txhais li cas los ntawm enantiomeric tshaj?
Enantiomeric ntau dhau (ee) yog kev ntsuas purity siv rau cov tshuaj chiral. Nws qhia txog qib uas ib qho piv txwv muaj ib qho enantiomer ntau dua li lwm tus. Ib qho kev sib xyaw racemic muaj ee ntawm 0%, thaum ib qho ntshiab ntshiab enantiomer muaj ee ntawm 100%.
Puas yog kho qhov muag purity tib yam li enantiomeric tshaj?
Yog li, qhov kho qhov muag purity yog li sib npaug rau feem pua ntawm cov enantiomer loj tshaj tus me enantiomer. Lo lus no, "enantiomeric tshaj", lossis "e.e." luv luv, yog sib npaug rau qhov kho qhov muag purity thiab yog siv ntau zaus rau kev nthuav qhia enantiomeric purity ntawm ib tug sib tov.
Thaum twg cov tshuaj tuaj yeem muaj enantiomeric ntau dhau?
Yog li ntawd, yog sib tov muaj 75% ntawm R enantiomer thiab 25% S, qhov enantiomeric tshaj yog 50%. Ib yam li ntawd, ib qho kev sib xyaw uas yog 95% ntawm ib qho enantiomer, qhov enantiomeric tshaj yog 90%, thiab lwm yam. Ib yam nkaus, cov enantiomeric tshaj nyob rau hauv ib qho sib tov tuaj yeem ntsuas tau yog tias qhov kev sib hloov kho qhov muag ntawm cov ntshiab enantiomer paub.
txhais li cas 94%enantiomeric tshaj?
txhais li cas 94% enantiomeric tshaj? Cov khoom | Chegg.com. Nrhiav. Dab tsi txhais tau tias 94% enantiomeric tshaj? Cov khoom muaj 94% ntawm ib qho enantiomer thiab 6% ntawm lwm cov enantiomer Cov khoom muaj 94% ntawm ib enantiomer thiab 6% ntawm lwm cov khoom Cov khoom muaj ib tug enantiomer uas yog 94% ntshiab.
