Qhov txawv ntawm benzaldehyde thiab benzophenone yog tias benzaldehyde yog aldehyde, whereas benzophenone yog ketone.
Ob leeg benzaldehyde thiab benzophenone yog cov tshuaj tsw qab carbonyl. Txawm li cas los xij, benzaldehyde muaj ib pawg phenyl txuas nrog cov pab pawg carbonyl vim tias sab nraud ntawm cov carbonyl carbon no muaj hydrogen atom vim nws yog aldehyde. Tab sis, hauv benzophenone, ob sab ntawm cov carbonyl carbon muaj phenyl pawg.
Benzaldehyde yog dab tsi?
Benzaldehyde yog ib qho tshuaj tsw qab aldehyde uas muaj cov tshuaj formula C6H5CHO. Nws muaj ib pab pawg phenyl txuas nrog aldehyde ua haujlwm pab pawg. Ntxiv mus, nws yog qhov yooj yim tshaj plaws aromatic aldehyde. Nws tshwm sim raws li cov kua uas tsis muaj xim thiab muaj cov ntxhiab tsw zoo li almond. Tsis tas li ntawd, nws cov molar loj yog 106.12 g / mol. Thiab, nws melting point yog -57.12 ° C thaum lub boiling point yog 178.1 ° C.
Daim duab 01: Cov qauv ntawm Benzaldehyde
Txog kev tsim cov benzaldehyde, txoj hauv kev tseem ceeb ntawm kev tsim cov tshuaj no yog kua theem chlorination thiab oxidation ntawm toluene. Txawm li cas los xij, qhov sib xyaw no kuj tshwm sim nyob rau hauv ntau yam khoom noj thiab; Piv txwv li, nyob rau hauv almonds. Yog li ntawd, ib qho ntawm cov kev siv loj ntawm cov tshuaj no yog nws siv los ua ib qho almond tsw hauv cov khoom noj thiab cov khoom tsw qab.
Benzophenone yog dab tsi?
Benzophenone yog ib qho tshuaj tsw qab ketone muaj cov tshuaj formula C13H10O. Nws yog ib qho tshuaj tsw qab ketone thiab muaj ob lub nplhaib benzene txuas rau tib lub atom ntawm carbonyl pawg. Peb tuaj yeem sau nws li Ph2O qhov twg Ph yog hais txog "phenol" (lwm lub npe rau benzene nplhaib).
Daim duab 02: Cov qauv ntawm Benzophenone
Saib ntawm cov khoom ntawm benzophenone, nws cov molar loj yog 182.22 g / mol. Nws muaj cov ntxhiab tsw zoo li geranium, thiab nws tshwm sim raws li cov khoom dawb ntawm tus qauv kub thiab siab. Ntxiv mus, cov compound no yog insoluble nyob rau hauv dej, tab sis, soluble nyob rau hauv ib co organic solvents. Lub melting point yog 48.5 ° C thaum lub boiling point yog 305.4 ° C. Dhau li ntawd, peb tuaj yeem tsim cov khoom sib xyaw no los ntawm tooj liab-catalyzed oxidation ntawm diphenylmethane nrog 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 Benzaldehyde thiab Benzophenone yog dab tsi?
Benzaldehyde yog ib qho tshuaj tsw qab aldehyde uas muaj cov tshuaj formula C6H5CHO thaum Benzophenone yog ib qho aromatic ketone muaj cov tshuaj formula C 13H10O. Yog li, qhov sib txawv tseem ceeb ntawm benzaldehyde thiab benzophenone yog tias benzaldehyde yog aldehyde, whereas benzophenone yog ketone. Tsis tas li ntawd, benzaldehyde muaj cov ntxhiab tsw zoo li almond, tab sis benzophenone muaj ntxhiab tsw zoo li geranium.
Ntxiv mus, thaum xav txog cov qauv tshuaj ntawm cov tshuaj no, qhov sib txawv ntawm benzaldehyde thiab benzophenone yog tias benzaldehyde muaj phenyl pawg txuas nrog aldehyde functional pawg, whereas benzophenone muaj ob pawg phenyl txuas rau ob sab ntawm carbonyl. carbon.
Hauv qab infographic qhia ntau qhov sib piv txog qhov sib txawv ntawm benzaldehyde thiab benzophenone.
Summary – Benzaldehyde vs Benzophenone
Benzaldehyde yog ib qho tshuaj tsw qab aldehyde uas muaj cov tshuaj formula C6H5CHO thaum Benzophenone yog ib qho aromatic ketone muaj cov tshuaj formula C 13H10O. Hauv cov ntsiab lus, qhov sib txawv tseem ceeb ntawm benzaldehyde thiab benzophenone yog tias benzaldehyde yog aldehyde, whereas benzophenone yog ketone.
