Phenoxyethanol thiab 2-phenoxyethanol yog rau feem ntau suav tias yog tib yam khoom **. Qhov no yog vim hais tias, nyob rau hauv lub teb ntawm chemistry, tshwj xeeb tshaj yog nyob rau hauv lub tswv yim daim ntaub ntawv uas muaj xws li industries xws li tshuaj pleev ib ce thiab tshuaj, phenoxyethanol feem ntau yog hais txog 2-phenoxyethanol.
1. Cov qauv tshuaj
Phenoxyethanol muaj nyob rau hauv ob hom: 1-phenoxyethanol thiab 2-phenoxyethanol. Qhov sib txawv tseem ceeb ntawm lawv yog txoj hauj lwm ntawm phenoxy linkage ntawm ethanol molecule. Hauv qhov no, pawg phenoxy ntawm 1-phenoxyethanol txuas nrog cov pa roj carbon uas cov pawg hydroxyl ntawm ethanol nyob, thaum pawg phenoxy ntawm 2-phenoxyethanol txuas rau lwm cov pa roj carbon monoxide.
Hauv kev siv tswv yim, txij li 2-phenoxyethanol tuaj yeem ua ke, phenoxyethanol feem ntau raug xa mus rau hauv khw feem ntau txhais tau tias 2-phenoxyethanol.
2, Lub cev muaj zog thiab kev siv
2-Phenoxyethanol (xws li phenoxyethanol) yog cov kua tsis muaj xim oily, me ntsis aroma thiab astringent hauv saj. Nws yog me ntsis soluble hauv dej, tab sis tuaj yeem sib xyaw nrog cov kuab tshuaj xws li acetone, ethanol thiab glycerol.
Raws li ib qho tseem ceeb ntawm cov organic compound, phenoxyethanol muaj ntau yam kev siv hauv ntau qhov chaw. Nyob rau hauv cov tshuaj pleev ib ce, nws yog feem ntau siv raws li ib tug preservative nrog tsawg toxicity thiab zoo stability. Nws kuj yog siv los ua ib qho fixative hauv cov tshuaj tsw qab, ua tshuaj tua kab, thiab ua tshuaj tua kab mob. Hauv kev lag luam tshuaj, phenoxyethanol yog siv los ua bactericide, preservative thiab hluavtaws raw khoom rau qee yam tshuaj. Tsis tas li ntawd, nws yog siv los ua tshuaj loog rau cov ntses hauv kev lag luam aquaculture.
3, Kev nyab xeeb thiab txwv
Kev siv phenoxyethanol hauv cov tshuaj pleev ib ce yog raug txwv nruj kom ntseeg tau tias nws muaj kev nyab xeeb. Feem ntau, phenoxyethanol yuav tsum tsis txhob siv rau hauv cov khoom siv tshuaj pleev ib ce ntawm ntau tshaj 1 feem pua (0.1-2 ib xees rau cov kev daws teeb meem, uas 10 feem pua ethanol ntxiv).
Txawm hais tias phenoxyethanol raug suav hais tias yog ib qho tshuaj tiv thaiv zoo, kev raug mob ntev ntev tuaj yeem ua rau muaj kev phiv xws li tawv nqaij khaus lossis ua xua. Yog li ntawd, thaum siv cov tshuaj pleev ib ce uas muaj phenoxyethanol, yuav tsum tau saib xyuas kom siv cov nqi tsim nyog thiab tshem tawm cov khoom ua - kom raws sij hawm kom txo tau qhov hnyav ntawm daim tawv nqaij.
Hauv cov ntsiab lus, phenoxyethanol thiab 2-phenoxyethanol tuaj yeem suav tau tias yog tib yam tshuaj nyob rau hauv feem ntau, nrog rau qhov zoo sib xws hauv cov qauv tshuaj, lub cev thiab kev siv. Txawm li cas los xij, hauv cov ntawv thov tshwj xeeb, tseem yuav tsum tau them nyiaj rau lawv cov cai txwv thiab teeb meem kev nyab xeeb.
