Qhov sib txawv tseem ceeb ntawm anisole thiab cresol yog tias anisol tsis hnov mob nrog nruab nrab ferric chloride, whereas cresol reacts nrog nruab nrab ferric chloride kom muab xim violet.
Anisole thiab cresol yog cov organic tebchaw uas yog txoj haujlwm isomers ntawm ib leeg. Ob lub tebchaw no muaj cov qauv tshuaj tib yam vim tias lawv yog isomers ntawm ib leeg. Txawm li cas los xij, ob lub tebchaw no muaj lub nplhaib benzene txuas rau lub atom oxygen. Nyob rau hauv anisol, cov pa atom no yog txuas mus rau ib pawg methyl functional, whereas nyob rau hauv cresol, cov pa atom yog txuas mus rau ib hydrogen atom, thiab muaj ib tug methyl pab pawg neeg txuas mus rau cov nyob ib sab carbon atom ntawm lub nplhaib benzene.
Anisole yog dab tsi?
Anisole yog cov organic compound uas muaj cov tshuaj formula CH3OC6H5. Qhov no yog ib qho ether compound uas muaj ib pawg methyl thiab ib pawg phenyl txuas rau tib lub hauv paus oxygen atom. Nws tshwm sim raws li cov kua tsis muaj xim thiab muaj ntxhiab tsw uas zoo li tus ntxhiab ntawm cov noob txiv ntoo. Peb tuaj yeem soj ntsuam lub xub ntiag ntawm qhov sib xyaw no hauv ntau cov tshuaj tsw qab ntuj thiab dag. Nws yog cov khoom siv hluavtaws uas peb tuaj yeem siv rau kev sib txuas ntawm lwm cov organic sib txuas ua ntej. Anisole tuaj yeem tsim los ntawm methylation ntawm sodium phenoxide nyob rau hauv lub xub ntiag ntawm dimethyl sulfate los yog methyl chloride.
Daim duab 01: Kev lag luam muaj Anisole
Anisole tuaj yeem dhau los ua cov tshuaj tsw qab electrophilic hloov pauv. Cov pab pawg methoxy ntawm qhov sib xyaw yog ib pawg ortho / para directing. Cov pab pawg methoxy no muaj kev cuam tshuam loj rau cov huab cua hluav taws xob ntawm lub nplhaib qauv txuas nrog oxygen atom. Tsis tas li ntawd, anisole tuaj yeem ua rau cov tshuaj tiv thaiv electrophilic ib yam nkaus. Piv txwv li, anisol reacts nrog acetic anhydride, tsim 4-methoxyacetophenone. Kev sib txuas ntawm ether ntawm qhov sib txuas no ruaj khov heev, tab sis pawg methyl tau yooj yim hloov los ntawm hydrochloric acid. Anisole feem ntau categorized raws li ib tug tsis muaj tshuaj lom compound, tab sis nws yog ib tug flammable kua.
Cresol yog dab tsi?
Cresol yog cov organic compound uas muaj cov tshuaj formula HO-C6H4-CH3. Txij li thaum nws muaj phenol hloov nrog ib pawg methyl, peb tuaj yeem hu nws "methylphenol" thiab. Ntxiv mus, cov compound no tuaj yeem yog ntuj lossis hluavtaws. Raws li kev hloov pauv ntawm pawg methyl, muaj peb tus qauv isomers ntawm cresol li ortho-, para- thiab meta-hloov cresol. Peb daim ntawv no tuaj yeem tshwm sim hauv tib qhov sib tov; Peb hu nws "tricresol." Feem ntau, cresol yog tau los ntawm thee tar. Cov ntaub ntawv hluavtaws yog tsim los ntawm methylation ntawm phenol. Tsis tas li ntawd, hydrolysis ntawm chlorotoluene tuaj yeem tsim cresol.
Daim duab 02: Cov Ntawv Sib Txawv ntawm Cresol Molecule
Ntxiv mus, cresol tuaj yeem muaj nyob hauv cov khoom, kua, lossis roj theem vim tias lawv cov ntsiab lus melting thiab boiling tsis deb ntawm chav tsev kub. Thaum raug huab cua ntev, qhov sib xyaw no tuaj yeem maj mam dhau oxidation. Feem ntau, cresol yog cov xim tsis muaj xim, tab sis muaj cov impurities tuaj yeem ua rau xim daj lossis xim av. Tsis tas li ntawd, cresol muaj cov ntxhiab tsw zoo li phenol tsw.
Dhau li ntawd, muaj ntau yam kev siv tseem ceeb ntawm cresol. Piv txwv li, nws yog ib qho tseem ceeb raws li ib tug precursor rau cov ntaub ntawv xws li yas, tshuaj tua kab, tshuaj, thiab dyes. Txawm li cas los xij, kev nqus tau los yog noj cresol tuaj yeem ua rau muaj kev phom sij rau peb. Qee cov tshuaj lom muaj xws li khaus tawv nqaij, qhov muag, qhov ncauj, thiab caj pas. Tsis tas li ntawd, nws tuaj yeem ua rau mob plab thiab ntuav.
Qhov txawv ntawm Anisole thiab Cresol yog dab tsi?
Anisole yog cov organic compound uas muaj cov tshuaj formula CH3OC6H5, thaum cresol yog cov organic compound uas muaj cov tshuaj formula HO-C6H4-CH3. Qhov sib txawv tseem ceeb ntawm anisole thiab cresol yog tias anisole tsis hnov mob nrog nruab nrab ferric chloride, whereas cresol reacts nrog nruab nrab ferric chloride kom muab xim violet.
Cov hauv qab no qhia txog qhov sib txawv ntawm anisole thiab cresol hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Anisole vs Cresol
Anisole thiab cresol yog cov organic tebchaw uas yog txoj haujlwm isomers ntawm ib leeg. Qhov sib txawv tseem ceeb ntawm anisole thiab cresol yog tias anisole tsis hnov mob nrog nruab nrab ferric chloride, whereas cresol reacts nrog nruab nrab ferric chloride kom muab xim violet.
