Qhov sib txawv tseem ceeb ntawm phenol thiab nonylphenol yog tias phenol muaj pawg hydroxyl hloov mus rau hauv lub nplhaib benzene whereas nonylphenol muaj ib pawg hydroxyl thiab lwm pawg organic hloov mus rau lub nplhaib benzene.
Cov tebchaw organic yog cov tshuaj lom neeg muaj cov pa roj carbon thiab hydrogen atoms. Yuav muaj lwm cov atoms xws li oxygen thiab sulfur atoms thiab. Phenol yog ib qho hnyav hauv cov tshuaj synthesis, thaum nonylphenol yog ib qho derivative ntawm phenol.
Phenol yog dab tsi?
Phenol yog cov organic compound pab tau raws li cov kuab tshuaj, thiab nws muaj cov tshuaj formula HO-C6H5Nws yog cov qauv uas muaj ntxhiab (muaj lub nplhaib benzene nrog kev hloov). Tsis tas li ntawd, nws tshwm sim raws li cov khoom dawb uas yog volatile. Ntxiv mus, phenol yog ib qho me me acidic compound vim muaj cov proton tshem tau ntawm pawg hydroxyl ntawm phenol. Txawm li cas los xij, peb yuav tsum tau ua tib zoo saib xyuas kom tsis txhob kub hnyiab.
Daim duab 01: Cov qauv dav dav ntawm Phenol
Peb tuaj yeem tau txais phenol los ntawm kev rho tawm los ntawm thee tar. Txawm li cas los xij, nws tsuas yog tsim los ntawm cov khoom siv roj av. Cov txheej txheem ntau lawm yog hu ua "cumene process". Cov khoom dawb ntawm phenol no muaj ntxhiab tsw qab. Nws yog soluble hauv dej vim nws polarity.
Tsis tas li ntawd, phenol nyhav dhau los ntawm kev hloov pauv hluav taws xob vim tias cov khoom siv hluav taws xob ib leeg ntawm cov pa atom tau pub rau lub nplhaib qauv. Yog li ntawd, ntau pawg, suav nrog halogens, acyl pawg, pawg sulfur-muaj, thiab lwm yam tuaj yeem hloov mus rau lub nplhaib no. Tsis tas li ntawd, phenol tuaj yeem txo qis rau benzene ntawm distillation nrog zinc plua plav.
Nonylphenol yog dab tsi?
Nonylphenol yog ib qho derivative ntawm phenol uas muaj cuaj carbon tail txuas rau phenol molecule. Cov tshuaj formula ntawm no compound yog C15H24O. Nonylphenol poob rau hauv qeb ntawm alkylphenols. Txawm li cas los xij, cov qauv ntawm nonylphenol tuaj yeem sib txawv me ntsis. Feem ntau, pawg nonyl txuas nrog lub nplhaib benzene ntawm para txoj haujlwm, tab sis nws kuj tuaj yeem sib txawv raws li txoj kev tsim khoom. Tsis tas li ntawd, qhov sib xyaw no muaj nyob rau hauv cov kua hauv lub xeev ntawm chav tsev kub, thiab nws tshwm hauv cov xim daj daj. Txawm li cas los xij, lub ntsiab lus ntshiab yog xim tsis muaj xim. Tsis tas li ntawd, qhov sib xyaw no yog dej-soluble me ntsis. Tab sis, nws zoo soluble hauv cawv.
Daim duab 02: Cov qauv dav dav ntawm Nonylphenol
Nonylphenol tuaj yeem tsim los ntawm kev degradation ntawm alkylphenol ethoxylates. Tsis tas li ntawd, peb tuaj yeem tsim cov khoom sib xyaw no hauv kev lag luam-teev ntawm alkylation ntawm phenol nrog cov sib tov ntawm nonenes nyob rau hauv muaj cov kua qaub catalyst.
Thaum xav txog nws cov ntawv thov, nonylphenol yog ib qho tseem ceeb hauv kev tsim cov tshuaj antioxidants, cov roj nplua nyeem ntxiv, cov kua ntxhua khaub ncaws, cov tshuaj ntxuav tais diav, emulsifiers, thiab solubilizers. Tsis tas li ntawd, nws yog siv los ua ib qho nruab nrab hauv kev tsim cov nonionic surfactants.
Qhov txawv ntawm Phenol thiab Nonylphenol yog dab tsi?
Phenol thiab nonylphenol yog cov organic tebchaw. Nonylphenol yog derivative ntawm phenol. Qhov sib txawv tseem ceeb ntawm phenol thiab nonylphenol yog tias phenol muaj cov pab pawg hydroxyl hloov mus rau hauv lub nplhaib benzene whereas nonylphenol muaj ib pawg hydroxyl thiab lwm pawg organic hloov mus rau lub nplhaib benzene. Thaum xav txog cov kev siv ntawm phenol, nws yog ib qho tseem ceeb raws li intermediates nyob rau hauv cov organic synthesis txheej txheem, raws li ib tug hnyav, raws li ib tug tshuaj tua kab mob, thiab lwm yam. Nonylphenol yog ib qho tseem ceeb nyob rau hauv manufacturing antioxidants, lubricant oil additives, ntxhua khaub ncaws kua, ntxuav tais diav, emulsifiers, thiab solubilizers.
Hauv qab infographic qhia txog qhov sib txawv ntawm phenol thiab nonylphenol.
Summary – Phenol vs Nonylphenol
Phenol thiab nonylphenol yog cov organic tebchaw. Nonylphenol yog derivative ntawm phenol. Qhov sib txawv tseem ceeb ntawm phenol thiab nonylphenol yog tias phenol muaj cov pab pawg hydroxyl hloov mus rau hauv lub nplhaib benzene whereas nonylphenol muaj ib pawg hydroxyl thiab lwm pawg organic hloov mus rau lub nplhaib benzene.
