Nyob rau tib lub sijhawm, nws cov derivatives tseem dav siv nyob rau hauv cov tshuaj pleev ib ce hnub ci, xws li bp -1}}}, kom cov tawv nqaij qeeb.
2. Lub teeb Catilility ua haujlwm
Los ntawm kev nqus cov ultraviolet rays nyob rau hauv sab nraud ib puag ncig thiab tso tawm rau hauv daim ntawv ntawm lub zog tawg, tiv thaiv teeb meem xws li kev hloov xim thiab cov khoom siv kho tshuab. Cov cuab yeej no yog qhov tshwj xeeb tshaj nyob rau hauv cov khoom yas (xws li PE, PP, PVC), tshwj xeeb cov ntaub ntawv siv nyob rau sab nraum zoov ib puag ncig.
3. Photosensitivity muaj nuj nqi
Benzophenone muaj qee yam duab kos duab thiab tuaj yeem txaus siab rau lub xeev travet, yog li txhawb nqa hluav taws xob hloov lossis dawb radical tshua muaj. Cov cuab yeej no ua rau nws tseem ceeb ntawm tus kws yees duab thaij duab, tshwj xeeb tshaj yog haum rau UV kho cov txheej txheem. Nws yog feem ntau siv nyob rau hauv UV lub teeb ci-kho inks, cov nplaum, cov luam ntawv ntxiv los txhim kho kev kho kom nrawm thiab cov tshuaj tiv thaiv kev ua haujlwm ntawm cov kab ke.
4. Ua haujlwm ntawm cov organic synthesis intermediates
Raws li ib qho yooj yim thiab reactive aromatic ketone, benzophenone tuaj yeem koom nrog ntau yam kev ua kom muaj zog xws li, thiab lwm yam kev ua kom zoo nkauj rau cov hluavtaws ntawm ntau hom sib txuas. Hauv cov chaw muag tshuaj, nws cov derivatives tuaj yeem siv los siv tshuaj tua kab mob, tshuaj xyuas thiab lwm hom tshuaj nquag molecules; Nyob rau tib lub sijhawm, nws kuj muaj qhov muaj txiaj ntsig zoo hauv cov khoom noj kom zoo xws li cov tshuaj tsw qab, ua kom zoo nkauj, thiab cov ntaub ntawv yees duab.
