Kev taw qhia luv luv
(S)-1-(4-chlorophenyl) ethanol yog cov organic compound. Nws yog chiral molecule nrog txuas ntxiv chiral nplhaib zoo li qauv. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm cov khoom sib xyaw no:
Zoo:
- Cov tsos mob: (S)-1-(4-chlorophenyl) ethanol yog cov kua tsis muaj xim rau lub teeb daj.
- Soluble: Nws tuaj yeem soluble hauv ntau cov kuab tshuaj organic, xws li cawv, ethers thiab aromatic hydrocarbons.
Siv:
- (S)-1-(4-chlorophenyl) ethanol feem ntau yog siv los ua ib qho nruab nrab hauv cov organic synthesis.
- Nws kuj tuaj yeem siv rau hauv kev npaj cov chiral compounds, chiral ligands, thiab chiral catalysts, thiab lwm yam.
Txoj kev:
- (S)-1-(4-chlorophenyl) ethanol tuaj yeem ua ke los ntawm cov kauj ruam hauv qab no:
1. Ethylene acetonitrile yog condensed nrog 4-chlorobenzaldehyde los ua N-[(4-chlorobenzene)methyl]ethyleneacetonitrile.
2. Qhov nruab nrab no yog ces rhuab nrog sodium hydroxide thiab ethanol los tsim (S)-1-(4-chlorophenyl) ethanol.
Cov ntaub ntawv kev nyab xeeb:
- (S)-1-(4-chlorophenyl) ethanol feem ntau muaj kev nyab xeeb nyob rau hauv kev ua haujlwm ib txwm muaj, tab sis tseem muaj qee cov txheej txheem kev nyab xeeb hauv kev ua haujlwm uas yuav tsum tau ua.
- Nws tuaj yeem ua rau lub qhov muag, tawv nqaij, thiab ua pa, thiab yuav tsum zam kom tsis txhob sib cuag ncaj qha thiab nqus pa. Cov cuab yeej tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab lub ntsej muag yuav tsum hnav thaum tuav.
- Thaum tuav lossis khaws cov khoom sib xyaw, yuav tsum tau saib xyuas kom tsis txhob muaj hluav taws kub thiab kub.
- Thaum siv thiab pov tseg, xa mus rau cov ntaub ntawv Kev Nyab Xeeb thiab cov ntawv sau tshuaj, thiab ua raws li cov lus qhia ua haujlwm kom ntseeg tau tias kev nyab xeeb thiab kev pheej hmoo ntawm kev noj qab haus huv raug txo qis.
