Indlela yohlalutyo lwe-chiral yeValinol
I-Fmoc-Valinol yalungiswa ngokusabela kwe-1mg / mg i-Valinol kunye ne-Fmoc-OSU.I-1mg i-valerine iguqulwe yi-Fmoc
Ichithwe nge-1ml ye-MEOH, i-2ml yesampuli yafakwa kwisixhobo sokuvavanya se-HPLC esiqhagamshelwe kwikholamu yovavanyo lwe-chiral.
Kwinqanaba lokuhamba kwe-0.5ml / s, i-FMOC-L-VALINOL iphakamileyo kwimizuzwana ye-19, i-FMOC-D-VALINOL iphezulu kwimizuzwana ye-58.
Indlela yokumisela ukujikeleza kweValinol
1. Emva kokuba i-powder ivuliwe, vula umbane kwaye ulinde i-15min ukwenza isibane se-sodium sikhanye ngokuzinzileyo.
2. Vula isibane somthombo wokukhanya, kwaye isibane sesodium sikhanyiswa phantsi konikezelo lwamandla e-DC.
3. Lungisa ityhubhu yovavanyo.
I-4, kwi-tube ilungiselelwe ukujova i-trichloromethane solvent, cinezela iqhosha elithi "zero", ukuze umboniso ube ngu-zero.
5. Susa i-solvent engenanto kwaye utofe isampuli ukuba ihlolwe.
I-6, ukulungiswa kwesampula: yithi isampuli ye-2.5g kunye nomthamo wamanzi ukuya kwi-25ml.
7. Cofa u-"Measurement" ukubonisa isiphumo somlinganiselo wokuqala, cofa u-"retest" ukubonisa isiphumo sesibini, kwaye ucinezele u-"Retest" kwakhona.
Isiphumo sesithathu siyaboniswa.
8. Ukubala:
