Cov lus piav qhia Benzophenone:
Benzophenone yog ib qho tsis muaj xim siv ua ke nrog lub qab zib thiab yws ntxig rau. Nws muaj lub ntsiab lus melting ntawm 47-49 ° C, ib tug txheeb ze ceev ntawm 1.1146, thiab ib qho ntsuas hluav taws xob tsis zoo ntawm 1.6077. Nws yog soluble hauv cov kuab tshuaj organic thiab monomers xws li Ethanlo, ether thiab chloroform, tab sis insoluble hauv dej. Nws yog tus dawb radical photioInitiator, feem ntau yog siv hauv kev dawb radical UV kho cov tshuab, xws li txheej, thiab lwm yam. Cov khoom no tseem yog cov tshuaj tsw qab polymerization thiab cov tshuaj tsw qab, thiab yog siv cov tshuaj tsw qab, thiab yog siv dav hauv cov naj hoom thiab xab npum flavors. Thaum lub sij hawm cia thiab tsheb thauj mus los, cov khoom yuav tsum tau tiv thaiv los ntawm noo noo, hnub, thiab deb ntawm cov cua sov, thiab nws qhov kub yuav tsum tsis pub tshaj 45 ° C.
