Lub ntsiab
Toluene-D8 丨 CAST 2037-26-5 yog qhov ruaj khov, tag nrho cov qauv kev sib tw thiab siv cov khoom siv sib nqus Nucent thiab siv) thiab cov tshuaj siv tshuaj tshwj xeeb.
Cov Ntawv Thov
1. NMR spectroscopy kuab tshuaj
Siv raws li aKev ua haujlwm ntawm cov kuab tshuajRau cov kev daws teeb meem NMR, tshwj xeeb hauv:
OrgisM Chemistry
Kev Tshawb Fawb Txog Kev Tshawb Fawb
Polymer tsom xam
Lub xub ntiag ntawm kev siv hydrogen minimizes cov cim tom qab nyob rau hauv Proton NMR Spectrum, txhim kho kev pom tseeb thiab daws teeb meem.
Muaj txiaj ntsig thaum kawm cov tebchaw rau hauv tsis-ncov qaumteb qab zib.
2. Sab Nraud Txuj Ci Hauv Kev Tshawb Xyuas Kev Lag Luam
Ua hauj lwm ua tus qauv sab hauv lossis cov ntaub ntawv sib txuas hauv:
Pawg Spectrometry (MS)
Roj Chromatography (GC)
Quantitive NMR (QNMR)
Qhov ISOTOPIC labeling pab kom paub qhov txawv ntawm nws kom meej los ntawm Anallyte cim.
3. Isotopic labeling hauv kev tshawb fawb kev kawm
Siv nyob rau hauvKinetic IsoTeope nyhuvKev sim thiab kev ntsuas kev tshawb fawb kom paub txog cov kev tshuaj tiv thaiv cov kev koom nrog Toluene derivatives.
Kev hloov ntawm cov hydrogen nrog rau deuterium tuaj yeem hloov cov kev tawm tsam, muab kev pom rau hauv kev ua txhaum / ua tiav cov txheej txheem.
4. Tshwj xeeb organic synthesis
Kev ua raws li cov kuab tshuaj lossis reagent nyob rau hauv cov kev xwm txheej uas muaj kevcoration deutercoration yog xav tau los tsimDeuterium-daim ntawv sau npe, Siv tau hauv cov tshuaj tshuaj lossis cov kev kawm ua si.
Cov txiaj ntsig
1. Qhov tsawg kawg ntawm kev cuam tshuam ntawm keeb kwm yav dhau los
Qhov hloov ntawm txhua qhov hydrogens los ntawm cov kev ua tau zoo los ntawm kev ua kom tsis muaj zog heev lossis tsis tuaj kawm ntawv tawm tsam los ntawm cov kuab tshuaj, txhim kho cov nmr spectra.
2. Tshuaj Ntsuam Xyuas Kev Ruaj Ntseg
Kev siv tshuaj lom thiab sov ruaj khov nyob rau hauv cov kab mob kev kuaj mob.
Resistant rau isotope sib pauv, khaws cia cov qauv kev txiav txim siab thaum lub sijhawm cia thiab siv.
3. Txhim kho qhov tseeb hauv kev txheeb xyuas qhov tseeb
Pab tswj cov txiaj ntsig kom paub tseeb hauv NMR thiab MS los ntawm kev muab lub cim zoo ib yam uas tsis muaj kev sib tshooj.
4. Versatility
Haum rau ntau yam ntawm cov tebchaw rau cov neeg sib txuas hauv cov kuab tshuaj uas muaj ntxhiab, nrog rau cov khoom tsis muaj-ncov qaumteb qab zib polar.
