Indlela Yokuhlaziya ye-L-Valinol (GC)
1 Isimiso Isampula ifakwa umhwamuko ngekholomu yechromatographic ukuze izingxenye ezizokalwa zihlukaniswe, bese kusetshenziswa umtshina we-hydrogen flame ionization ukuze kutholwe inombolo.Okuqukethwe okuphezulu okuphezulu kukalwa ngokuya ngendlela.
2. Insimbi
I-Carrier gas: ngaphezu kuka-99.95% we-nitrogen
Igesi: i-hydrogen engaphezu kuka-99.95%.
Igesi elisizayo: umoya ongaphezu kuka-99.95%.
I-Chromatograph: I-Lunan Chemical Instrument Factory 6800A igesi chromatograph
Ikholomu: SE-54 ikholomu ye-capillary (30M)
Umtshina: umtshina we-hydrogen flame ionization.
3. I-reagent yesicelo: i-ethanol
4. Izimo zokuhlola
Izinga lokushisa lomtshina: 250 ℃
Izinga lokushisa lekamelo elishisayo: 250 ℃
Izinga lokushisa lekholomu: 160 ℃
Ingcindezi yangaphambi kwekholomu: 0.05MPa
IHydrojeni: 0.06MPa
Umoya: 0.06MPa
Usayizi wesampula: 0.1ul
Isilinganiso se-Shunt: 50:1
Ukulungiswa kwesampula: Isampula ichithwa ku-ethanol
Indlela yokuhlaziya i-chiral ye-Valinol
I-Fmoc-Valinol yalungiswa ngokusabela kwe-1mg/mg Valinol nge-Fmoc-OSU.I-1mg ye-valerine elungiswe yi-Fmoc
Ihlakazwe ngo-1ml we-MEOH, u-2ml wesampula ujovwe kudivayisi yokuhlola ye-HPLC exhunywe kukholomu yokuhlola i-chiral
Kuzinga lokugeleza elingu-0.5ml/s, i-FMOC-L-VALINOL iphakama ngamasekhondi angu-19, i-FMOC-D-VALINOL iphakama ngamasekhondi angu-58.
Indlela yokunquma ukujikeleza kwe-Valinol
1. Ngemva kokuba impushana ivuliwe, vula inkinobho yamandla bese ulinda i-15min ukwenza isibani se-sodium sikhanye ngokuzinzile.
2. Vula iswishi yomthombo wokukhanya, futhi isibani sesodium sikhanyiswa ngaphansi kwamandla kagesi e-DC.
3. Lungisa ishubhu lokuhlola.
4, ku-tube kulungiselelwe ukujova i-trichloromethane solvent, cindezela ukhiye "zero", ukuze isibonisi sibe nguziro.
5. Khipha i-solvent engenalutho bese ujova isampula ukuze ihlolwe.
6, ukulungiswa kwesampula: ithi 2.5g isampula enomthamo wamanzi ukuya ku-25ml.
7. Cindezela u-"Measurement" ukuze ubonise umphumela wokuqala wokulinganisa, cindezela u-"retest" ukuze ubonise umphumela wesibili, bese ucindezela u-"Hlola kabusha" futhi.
Umphumela wesithathu uyavezwa.
