Zoo siv
Tshuaj lom neeg:Lwm Cov Chav Kawm -> Benzophenones
Canonical luag nyav:C1 = CC = C (C = C1) C (= O) C2 = CC = CC = C2
Inhalation kev pheej hmoo:Evaporation ntawm 20 ° C yog negligible; Kev thab plaub-ua rau muaj kev kub siab ntawm cov pa pa hluav taws xob tuaj yeem, tau mus txog sai sai thaum tawg.
Qhov cuam tshuam ntawm kev sib kis luv luv:Cov tshuaj yog me me khaus rau daim tawv nqaij.
Qhov cuam tshuam ntawm kev raug mob ntev:Cov tshuaj yuav muaj teebmeem ntawm daim siab thiab lub raum, ua rau muaj kev tsis taus. Cov qog tau kuaj pom hauv cov tsiaj sim tab sis yuav tsis cuam tshuam rau tib neeg.
