Qhov sib txawv tseem ceeb ntawm acetophenone thiab benzophenone yog tias acetophenone muaj methyl pawg thiab lub nplhaib benzene txuas nrog carbonyl carbon, whereas benzophenone muaj lub nplhaib benzene txuas nrog carbonyl carbon.
Ob leeg acetophenone thiab benzophenone yog cov organic tebchaw uas poob rau hauv qeb ntawm ketones vim tias ob lub tebchaw no muaj carbonyl carbon nrog alkyl lossis aryl pawg txuas rau ob sab. Ntxiv mus, cov tebchaw no muaj lub nplhaib benzene txuas rau carbon atom ntawm pawg carbonyl.
Acetophenone yog dab tsi?
Acetophenone yog cov organic compound uas muaj cov tshuaj formula C8H8O. Nws yog ketones, thiab nws yog ketone yooj yim tshaj plaws ntawm cov ketones aromatic. Lub npe IUPAC ntawm cov tshuaj no yog 1-Phenylethane-1-ib. Lwm cov npe muaj xws li methyl phenyl ketone thiab phenylethanone.
Xav txog nws cov khoom, cov molar loj yog 120.15 g / mol. Tsis tas li ntawd, lub melting point yog nyob ntawm 19-20 ° C thaum lub boiling point yog 202 ° C. Thiab, qhov sib xyaw no tshwm sim raws li cov xim tsis muaj xim, kua nplaum. Tsis tas li ntawd, peb tuaj yeem tau txais nws ua cov khoom lag luam los ntawm oxidation ntawm ethylbenzene los ua ethylbenzene hydroperoxide.
Daim duab 01: Cov qauv ntawm Acetophenone
Thaum xav txog kev siv acetophenone, hauv kev lag luam nplai, nws yog ib qho tseem ceeb ua cov khoom ua ntej rau kev tsim cov resins, ua cov khoom xyaw hauv cov tshuaj tsw qab, thiab lwm yam. Peb tuaj yeem hloov nws mus rau hauv styrene, thiab nws muaj txiaj ntsig zoo kev tsim kho ntau yam tshuaj thiab.
Benzophenone yog dab tsi?
Benzophenone yog cov organic compound uas muaj cov tshuaj formula C13H10O. Nws yog ib qho tshuaj tsw qab ketone, thiab nws muaj ob lub nplhaib benzene txuas rau tib lub atom ntawm carbonyl pawg. Peb tuaj yeem sau nws li Ph2O – Ph yog hais txog "phenol" (lwm lub npe rau benzene nplhaib).
Daim duab 02: Cov qauv ntawm Benzophenone
Saib ntawm nws cov khoom, cov molar loj ntawm benzophenone yog 182.22 g / mol. Thiab, nws melting point yog 48.5 ° C thaum lub boiling point yog 305.4 ° C. Ntxiv mus, nws muaj geranium-zoo li tsw thiab tshwm sim raws li ib tug dawb khoom ntawm tus qauv kub thiab siab. Tsis tas li ntawd, qhov sib xyaw no yog insoluble hauv dej tab sis soluble hauv qee cov organic solvents. Txog kev tsim khoom, peb tuaj yeem tsim cov khoom sib xyaw no los ntawm tooj liab-catalyzed oxidation ntawm diphenylmethane nrog huab cua.
Thaum xav txog kev siv benzophenone, nws yog ib qho tseem ceeb ua lub tsev thaiv rau kev sib txuas ntawm ntau cov organic tebchaw, ua tus yees duab-initiator hauv UV curing daim ntaub ntawv, raws li UV blocker rau cov pob yas, thiab lwm yam.
Qhov txawv ntawm Acetophenone thiab Benzophenone yog dab tsi?
Acetophenone yog cov organic compound uas muaj cov tshuaj formula C8H8O thaum Benzophenone yog cov organic compound uas muaj cov tshuaj formula C 13H10O. Qhov sib txawv tseem ceeb ntawm acetophenone thiab benzophenone yog tias acetophenone muaj methyl pawg thiab lub nplhaib benzene txuas rau carbonyl carbon, thaum benzophenone muaj lub nplhaib benzene txuas nrog carbonyl carbon. Tsis tas li ntawd, cov molar loj ntawm acetophenone yog 120.15 g / mol, thaum molar loj ntawm benzophenone yog 182.22 g / mol.
Ntxiv mus, hais txog cov khoom, qhov sib txawv ntawm acetophenone thiab benzophenone yog tias acetophenone yog dej-soluble tsis zoo, whereas benzophenone yog insoluble hauv dej. Tsis tas li ntawd, peb tuaj yeem tau txais acetophenone ua cov khoom lag luam los ntawm oxidation ntawm ethylbenzene los ua ethylbenzene hydroperoxide, thaum peb tuaj yeem tsim benzophenone los ntawm tooj liab-catalyzed oxidation ntawm diphenylmethane nrog cua.
Summary – Acetophenone vs Benzophenone
Acetophenone yog cov organic compound uas muaj cov tshuaj formula C8H8O thaum Benzophenone yog cov organic compound uas muaj cov tshuaj formula C 13H10O. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm acetophenone thiab benzophenone yog tias acetophenone muaj ib pawg methyl thiab lub nplhaib benzene txuas nrog carbonyl carbon, whereas benzophenone muaj lub nplhaib benzene txuas nrog carbonyl carbon.
