Qhov txawv ntawm Phenoxyethanol thiab Benzyl Cawv yog dab tsi

Muaj qhov sib txawv tseem ceeb ntawm phenoxyethanol thiab benzyl cawv hauv ntau yam. Cov hauv qab no yog cov ncauj lus kom ntxaws sib piv thiab cov ntsiab lus ntawm cov ntsiab lus:
Cov qauv tshuaj thiab cov khoom
Phenoxyethanol:
Cov tshuaj formula: C ₈ H ₁₀ O ₂
Nws yog ib qho organic compound synthesized los ntawm etherification ntawm ethylene glycol thiab phenol.
Nws yog cov kua tsis muaj xim thiab me ntsis viscous nrog cov ntxhiab tsw, me ntsis soluble hauv dej, thiab yooj yim soluble hauv ethanol thiab sodium hydroxide.
Tsawg toxicity, LD (tsawg koob tshuaj ntawm 50%) yog 3000mg / kg ntawm qhov ncauj rau nas thiab 4000mg / kg ntawm qhov ncauj rau cov nas.
Benzyl cawv:
Cov tshuaj formula: C ₇ H ₈ O
Nws yog ib qho organic compound nrog cov ntxhiab tsw tsis muaj zog, yooj yim soluble hauv aromatic hydrocarbons, ethers, thiab cawv, thiab me ntsis soluble hauv dej.
Cov tsos yog xim tsis muaj xim, pob tshab los yog kua dawb, nrog rau cov khoom siv tshuaj lom neeg, volatility, antibacterial zog, tsawg toxicity, thiab flammability.
lub hom phiaj
Phenoxyethanol:
Feem ntau yog siv los ua cov tshuaj tua kab mob hauv cov tshuaj pleev ib ce thiab cov khoom tu tawv nqaij, nws muaj cov tshuaj tua kab mob thiab cov tshuaj tua kab mob tshwj xeeb tiv thaiv Pseudomonas aeruginosa.
Raws li ib qho hnyav rau cov tshuaj thiab ib feem ntawm cov tshuaj tiv thaiv nyob rau hauv kws tshuaj.
Siv hauv kev lag luam ua cov kuab tshuaj, roj chromatography nyob twj ywm kua, thiab lwm yam.
Benzyl cawv:
Siv dav hauv tshuaj, tshuaj, zaub mov thiab lwm yam lag luam, suav nrog cov kuab tshuaj, tshuaj tsw qab, tshuaj intermediates, thiab lwm yam.
Siv los ua cov tshuaj tua kab mob hauv cov tshuaj pleev ib ce, nws muaj kev cuam tshuam zoo rau cov pwm thiab qee cov kab mob.
Corrosion Resistance
Phenoxyethanol:
Thaum siv ib leeg, cov nyhuv tsis zoo thiab nws feem ntau siv ua ke nrog lwm cov tshuaj tua kab mob.
Cov tshuaj tua kab mob ntawm Pseudomonas aeruginosa yog qhov zoo, thiab qhov zoo tshaj pH rau cov kab mob tua kab mob yog 3-9.
Qhov nyiaj siab tshaj ntxiv yog 1%.
Benzyl cawv:
Nws muaj cov nyhuv inhibitory zoo ntawm cov kab mob thiab qee cov kab mob, tab sis yuav ua tsis tau raws li qee yam kev mob (xws li nrog qee yam uas tsis yog-ionic surfactants thiab pH tsawg dua 5).
Qhov siab tshaj plaws pub dawb feem ntau yog 0.1%.
Kev ruaj ntseg
Phenoxyethanol:
Tsawg toxicity, suav hais tias muaj kev nyab xeeb thaum siv los ua cov khoom noj.
Kev siv hauv tshuaj pleev ib ce yog saib xyuas.
Benzyl cawv:
Nws kuj muaj cov tshuaj toxicity qis dua, tab sis nyob rau qee qhov xwm txheej (xws li kev noj haus ntau) nws kuj yuav ua rau muaj teeb meem kev noj qab haus huv.
Cov ntsiab lus
Muaj qhov sib txawv tseem ceeb ntawm phenoxyethanol thiab benzyl cawv nyob rau hauv cov ntsiab lus ntawm cov qauv tshuaj, khoom siv, kev siv, thiab kev tiv thaiv corrosion. Phenoxyethanol feem ntau yog siv los ua cov tshuaj tiv thaiv thiab hnyav hauv cov tshuaj pleev ib ce thiab tshuaj, thaum benzyl cawv yog siv dav hauv ntau qhov chaw lag luam. Hauv cov tshuaj pleev ib ce, ob qho tib si tuaj yeem siv ua cov tshuaj tua kab mob, tab sis phenoxyethanol muaj cov kab mob tua kab mob dav dua thiab feem ntau siv ua ke nrog lwm cov tshuaj tua kab mob. Hais txog kev nyab xeeb, ob qho tib si suav hais tias muaj kev nyab xeeb, tab sis cov qauv tsim thiab cov kev cai tseem yuav tsum tau ua raws li thaum siv.
