Eugenolyog ib yam khoom ntuj tsim nyob rau hauv cov roj geranol, cais los ntawm cov nroj tsuag xws li clove roj (Cloves roj), nutmeg roj (Nutmeg roj), cinnamon roj (Cinnamon roj) thiab dill roj (Basil roj) tau. Eugenol muaj txiaj ntsig zoo ntawm daim ntawv thov, xws li tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tua kab mob, tshuaj tua kab mob thiab lwm yam teebmeem, yog li nws tau nyiam ntau yam.
Eugenol yog ib yam khoom ntuj tsim nyob rau hauv cov roj yam tseem ceeb ntawm qee cov nroj tsuag, xws li roj clove thiab cinnamon roj. Eugenol muaj ntau yam kev ua haujlwm lom neeg, xws li tshuaj tiv thaiv oxidation, tshuaj tiv thaiv kab mob, tshuaj tua kab mob, tshuaj tua kab mob, thiab lwm yam, thiab muaj ntau yam kev siv tshuaj, zaub mov, txuj lom, thiab lwm yam.
1. Pharmaceutical teb:
Eugenol muaj analgesic, anti-inflammatory thiab bactericidal teebmeem, yog li nws yog dav siv nyob rau hauv kev kho mob ntawm qhov ncauj kab mob. Cov roj yam tseem ceeb xws li roj clove thiab cinnamon roj muaj cov Eugenol ntau, uas tuaj yeem siv los kho cov teeb meem ntawm qhov ncauj xws li pulpitis, gingivitis, thiab stomatitis. Tsis tas li ntawd, Eugenol kuj tau siv dav hauv kev tsim tshuaj. Piv txwv li, Eugenol yuav tsum muaj rau kev sib txuas ntawm cov tshuaj aspirin thiab lwm yam tshuaj.
2. Zaub mov teb:
Eugenol tuaj yeem siv los ua zaub mov ntxiv, feem ntau yog rau seasoning thiab khaws cia. Noj clove ua piv txwv, nws tuaj yeem siv los ua cov khoom noj xws li hnyuv ntxwm, nqaij npua, kas fes, thiab lwm yam, muab nws qhov tshwj xeeb aroma thiab saj. Tsis tas li ntawd, Eugenol kuj tuaj yeem ua tshuaj tua kab mob thiab ua kom cov zaub mov tshiab. Piv txwv li, ntxiv Eugenol rau cov khoom noj nqaij tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob.
3. Fragrance teb:
Eugenol yog cov khoom siv tshuaj tsw qab ntuj, uas kuj tau siv dav hauv cov tshuaj tsw qab. Piv txwv li, hauv xab npum, naj hoom, lipsticks, scented tswm ciab thiab lwm yam khoom, Eugenol tuaj yeem muab ntxiv kom muab cov ntxhiab tsw tshwj xeeb. Lub aroma ntawm Eugenol yog dav siv nyob rau hauv tshuaj pleev ib ce, perfumes, lub qhov ncauj fresheners, ntaub hoob nab thiab lwm yam khoom.
Nyob rau hauv luv luv, Eugenol plays lub luag haujlwm tseem ceeb hauv kev kho mob, zaub mov thiab txuj lom. Yog li ntawd, kev tsim khoom thiab kev tshawb fawb ntawm Eugenol tau dhau los ua neeg nyiam nyob rau xyoo tas los no.
Txij li thaum Eugenol tau muab rho tawm thawj zaug hauv xyoo 1870, ntau txoj hauv kev tau tsim los ua kom cov khoom sib xyaw no. Txog tam sim no, ntau txoj kev sib txawv hluavtaws tau pom. Cov ntawv tshaj tawm no yuav qhia qee txoj hauv kev paub thiab sib piv lawv qhov zoo thiab qhov tsis zoo.
1. Ib-kauj ruam synthesis los ntawm guaiacol thiab aldehyde:
Cov txheej txheem hluavtaws no yog thawj zaug los ntawm R.Post hauv xyoo 1907. Cov txheej txheem ntawm cov tshuaj tiv thaiv yog npaj los ntawm cov tshuaj tiv thaiv ntawm guaiacol thiab aldehyde nyob rau hauv lub xub ntiag ntawm sodium hydroxide. Txawm li cas los xij, txoj kev no muaj qhov tsis zoo pom tseeb: thawj zaug, cov txiaj ntsig qis, tsuas yog kwv yees li 30-40 feem pua ; Qhov thib ob, vim hais tias cov tshuaj tiv thaiv yuav hloov cov pab pawg hydroxyl nyob rau hauv lub nplhaib furan nrog cov pab pawg hydroxyl ntawm lub nplhaib benzene, nws yuav tsum tau noj ntau ntawm catalyst.
2. Synthesized los ntawm clove roj los ntawm alkaline hydrolysis thiab txo txoj kev:
Txoj kev no yog muab cov roj clove rau hauv cawv rau alkaline hydrolysis, condense nrog txhuas nitrate los tsim 2-methoxy-4-hydroxystyrene, thiab tom qab ntawd nqa tawm cov coupling los tsim eugenol.
Lub ntsiab kom zoo dua ntawm cov tshuaj tiv thaiv no yog qhov (kuj) hloov pauv ntawm cov roj clove rau eugenol. Txawm li cas los xij, lub ntsiab tsis zoo ntawm txoj kev no yog lub siab toxicity thiab flammability ntawm cov reactants ntawm eugenol.
3. Tsim eugenol los ntawm acetophenone:
Txoj kev sib xyaw no yog kom condense acetophenone nrog guanosine los yog inosine nyob rau hauv lub xub ntiag ntawm lub hauv paus, ua raws li los ntawm reductive coupling los tsim eugenol.
Qhov kom zoo dua ntawm txoj kev no yog tias cov khoom pib rau cov tshuaj tiv thaiv no yooj yim rau kev npaj, cov txiaj ntsig tau siab (siab dua 85 feem pua), thiab tsis tas yuav siv cov tshuaj phem. Hmoov tsis zoo, qhov tsis zoo ntawm txoj kev no yog tias cov txheej txheem tshuaj tiv thaiv yog qhov nyuaj heev thiab yuav tsum tau siv sijhawm ntev thiab kev kub ntxhov.
4. Tsim eugenol los ntawm benzoic acid:
Cov tshuaj tiv thaiv yog nqa tawm Knoevenagel condensation ntawm benzoic acid thiab aldehyde nyob rau hauv lub xub ntiag ntawm tetrahydrofuran thiab potassium hydroxide kom tau txais 4-hydroxy-3- methoxystyrene, thiab tom qab ntawd nqa tawm lub nplhaib kaw cov tshuaj tiv thaiv thaum muaj tooj liab iodide rau Thaum kawg tau eugenol.
Qhov zoo ntawm txoj kev no suav nrog kev ua haujlwm yooj yim, cov khoom siv pheej yig, cov khoom lag luam siab (tshaj li 80 feem pua), thiab rov siv tau cov tshuaj hnyav. Txawm li cas los xij, qhov tsis zoo yog lub sijhawm ntev cov tshuaj tiv thaiv ntawm txoj kev hluavtaws no.
Hauv kev xaus, txawm hais tias eugenol tau ua tiav zoo los ntawm ntau txoj hauv kev, txhua txoj kev muaj qee qhov tsis zoo. Txoj kev xaiv twg feem ntau yog nyob ntawm yam xws li kev xav tau ntau lawm, txheej txheem txheej txheem thiab cov nqi lag luam.
Eugenol, phenylacetone derivative nrog cov tshuaj formula C10H12O2, yog ib qho tseem ceeb ntawm cov khoom ntuj tsim. Nws cov khoom siv tshuaj muaj feem xyuam rau nws cov solubility hauv dej, nws cov reactivity thiab nws cov haujlwm tshwj xeeb. Cov tshuaj lom neeg ntawm Eugenol tau piav qhia hauv qab no.
1. Solubility:
Eugenol yog qhov sib xyaw nrog cov organic ua haujlwm. Nws yog ib tug fat-soluble compound nrog tsawg solubility. Solubility hauv dej yog li ntawm 0.5mg/mL, tab sis nws tuaj yeem yaj hauv cov kuab tshuaj xws li ethanol, chloroform thiab acetone. Yog li ntawd, thaum siv Eugenol, nws yog ib qho tsim nyog yuav tau xaiv cov kuab tshuaj uas tsim nyog los yaj nws. Nyob rau tib lub sijhawm, Eugenol yuav decompose nyob rau hauv kev co, yog li yuav tsum tau saib xyuas kom tsis txhob muaj kev vibration thaum khaws cia, thauj thiab siv.
2. Reactivity:
Eugenol yog ib qho tshuaj reactive uas yog tshuaj reactive thiab muaj peev xwm ua tau ntau yam tshuaj tiv thaiv. Eugenol molecules muaj cov pab pawg ua haujlwm xws li benzene nplhaib, allyl pawg thiab hydroxyl pawg, uas ua rau nws muaj ntau yam kev cuam tshuam. Eugenol tuaj yeem ua rau cov kua qaub, alkalis, oxidants, thiab lwm yam. Piv txwv li, Eugenol thiab sodium hydroxide tuaj yeem ua rau cov kua qaub-puag los tsim cov ntsev ntsev; Eugenol thiab hydrogen peroxide tuaj yeem raug oxidation cov tshuaj tiv thaiv los tsim cov khoom xws li tannic acid.
3. Cov pab pawg ua haujlwm tshwj xeeb:
Eugenol molecules muaj cov pab pawg ua haujlwm xws li benzene nplhaib, allyl pawg thiab hydroxyl pawg, uas ua rau nws muaj cov haujlwm tshwj xeeb thiab kev siv. Ntawm lawv, benzene nplhaib thiab allyl functional pawg ua rau nws muaj cov kab mob zoo thiab cov tshuaj tua kab mob antioxidant, yog li Eugenol tuaj yeem siv los ua cov kab mob ntuj tsim, antioxidant thiab tshuaj tsw qab. Cov pab pawg ua haujlwm hydroxyl ua rau nws muaj hydrophilicity zoo, yog li Eugenol tuaj yeem siv los ua ke qee cov dej-soluble polymers.
4. Lwm yam kev tshwm sim:
Eugenol tuaj yeem ua rau qee qhov kev cuam tshuam, xws li cov tshuaj tiv thaiv esterification, cov tshuaj tsw qab halogenation thiab lwm yam. Cov tshuaj tiv thaiv esterification yog ib qho ntawm cov tshuaj tiv thaiv feem ntau ntawm Eugenol, uas siv cov pab pawg hydroxyl ntawm Eugenol los teb nrog cov kua qaub los ua ib qho ester. Tsis tas li ntawd, Eugenol kuj tseem tuaj yeem npaj cov khoom sib xyaw xws li chloro-Eugenol, bromo-Eugenol thiab iodo-Eugenol los ntawm cov tshuaj tsw qab halogenation.
Cov saum toj no yog cov khoom tseem ceeb ntawm Eugenol. Eugenol muaj cov ntawv thov siab heev thiab tuaj yeem siv rau ntau qhov chaw xws li tshuaj lom neeg, tshuaj, thiab kev lag luam khoom noj. Nyob rau tib lub sijhawm, Eugenol kuj muaj qee yam toxicity, yog li nws yuav tsum tau siv kom zoo.
