Daim duab 01: Cov Qauv Tshuaj ntawm R thiab S Carvone Molecules
R carvone yog ib qho tseem ceeb rau cov khoom cua freshening. Zoo ib yam li ntau lwm cov roj tseem ceeb, cov roj uas muaj carvone yog ib qho tseem ceeb hauv aromatherapy thiab lwm yam tshuaj. Nws zoo nkaus li cov kua ntshiab, tsis muaj xim uas yog insoluble hauv dej tab sis me ntsis soluble hauv dej kub. Txawm li cas los xij, nws yog soluble hauv ethanol, chloroform, thiab diethyl ether. Tsis tas li ntawd, R carvone tau pom zoo los ntawm US lub koom haum tiv thaiv ib puag ncig kom siv los ua cov khoom siv tshuaj yoov tshaj cum.
Feem ntau, peb yuav tsum siv qee qhov kev kho mob ntxiv rau kev tsim cov purity R carvone. Peb tuaj yeem ua qhov no los ntawm kev tsim cov tshuaj ntxiv nrog hydrogen sulfide. Nyob ntawd, carvone tuaj yeem rov tsim dua los ntawm kev kho nrog potassium hydroxide hauv ethanol, tom qab ntawd los ntawm distillation ntawm cov khoom nyob rau hauv ib tug tam sim no ntawm chav.
S Carvone yog dab tsi?
S carvone yog qhov sib txawv isomer ntawm R carvone. Cov pab pawg ua haujlwm ntawm cov molecule no yog teem rau hauv ib lub clockwise kev taw qhia. Nws yog stereoisomer ntawm R carvone. Ntxiv mus, S carvone yog qhov tsawg dua isomer ntawm carvone. Peb tseem tuaj yeem hu nws Dextro lossis D carvone.
Daim duab 02: Tus qauv ntawm S Carvone
Muaj ntau cov ntawv thov tseem ceeb ntawm S carvone. Piv txwv li, nws muaj txiaj ntsig zoo hauv kev lag luam khoom noj rau kev siv flavoring. Ntxiv mus, nws qhia tau hais tias muaj kev cuam tshuam los tiv thaiv kev noj zaub mov muaj rog uas tuaj yeem ua rau muaj qhov hnyav nce hauv cov nas. Tsis tas li ntawd, cov isomer no muaj txiaj ntsig zoo hauv kev ua liaj ua teb rau kev tiv thaiv ntxov ntxov sprouting ntawm qos yaj ywm thaum khaws cia. Nws tseem yog ib qho tseem ceeb hauv kev tsim cov terpenoid quassin.
Qhov txawv ntawm R thiab S Carvone yog dab tsi?
R carvone thiab S carvone yog enantiomers ntawm ib leeg. Qhov sib txawv tseem ceeb ntawm R thiab S carvone yog tias R carvone yog cov khoom siv carvone ntau tshaj plaws thiab muaj cov ntxhiab tsw qab ntxiag, thaum S carvone yog cov khoom siv tsawg dua thiab muaj cov ntsim ntsim nrog cov ntawv sau ntawm rye. Ntxiv mus, R carvone yog siv nyob rau hauv cov zaub mov flavoring, ib qho tseem ceeb rau huab cua freshening khoom, tsim ntawm yoov tshaj cum, thiab lwm yam., whereas S carvone yog siv nyob rau hauv cov zaub mov flavoring, qhia suppressant nyhuv tawm tsam ib tug high-rog noj, tiv thaiv ntxov ntxov sprouting ntawm qos yaj ywm thaum lub sij hawm. cia, synthesizing terpenoid quassin, thiab lwm yam.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm R thiab S carvone hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – R vs S Carvone
