4-Hydroxybenzophenone, tseem hu ua p-benzoylphenol thiab p-hydroxybenzophenone, yog dawb crystalline hmoov tshuaj nrog molecular mis C13H10O2 thiab molecular hnyav 198, uas tuaj yeem tau los ntawm cua sov thiab rov kho benzoic acid phenyl ester.Nws feem ntau yog siv rau hauv cov organic synthesis thiab yog ib qho nruab nrab ntawm cov tshuaj tiv thaiv infertility exoclomiphene.Nws yog khaus rau qhov muag, ua pa thiab tawv nqaij, tsis txhob sib cuag nrog daim tawv nqaij thiab qhov muag.
Xwm thiab Stability:
Tsis muaj decomposition yog siv thiab khaws cia raws li cov lus qhia tshwj xeeb, tsis paub txog kev phom sij, zam oxides
Txoj kev khaws cia:
Khaws cov khoom ntim khoom ntim, khaws cia hauv qhov chaw txias, qhuav, thiab ua kom muaj cua zoo lossis tso pa tawm hauv chav ua haujlwm
Synthesis Methods:
Thaum tshav kub kub benzoic acid phenyl ester rau 70 ℃ yaj, nplawm sai sai rau hauv anhydrous aluminium trichloride, cov tshuaj tiv thaiv tawm hydrogen chloride, thiab nws tus kheej cua sov, cov tshuaj tiv thaiv ntawm 130 ℃ rau 15 min.txias, ntxiv dilute hydrochloric acid.Lim thiab ntxuav nrog dej kom nruab nrab.Lub ncuav mog qab zib lim tau recrystallized nrog benzene muab 4-hydroxydiphenyl ketone hauv 62% tawm los.
Kev piav qhia ntawm kev siv:
Siv nyob rau hauv cov organic synthesis, tshuaj intermediates thiab anti-UV.
Cov ntaub ntawv ecological:
Muaj kev phom sij me ntsis rau dej Tsis txhob cia cov khoom tsis muaj tshuaj lom lossis ntau cov khoom tuaj yeem nkag mus rau hauv av, dej los yog cov kav dej phwj, thiab tsis txhob tso cov khoom pov tseg rau hauv ib puag ncig yam tsis tau tso cai los ntawm tsoomfwv.
