Taw qhia
4,4′-Dimethylbenzophenone. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 4,4'-dimethylbenzophenone:
Zoo:
4,4′-Dimethylbenzophenone yog cov xim tsis muaj kob crystalline uas tsis zoo soluble hauv dej ntawm chav tsev kub, tab sis soluble hauv organic solvents xws li cawv thiab esters.
Siv: Nws kuj tseem siv tau los ua ib qho nruab nrab hauv cov organic synthesis rau kev sib txuas ntawm lwm cov tebchaw.
Txoj kev:
Ib txoj kev npaj siv feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm benzophenone thiab n-butylformaldehyde nyob rau hauv alkaline tej yam kev mob. Cov kauj ruam tshwj xeeb synthesis yuav suav nrog cov cim diazonium ntsev ntawm ketones lossis oxime, uas txo qis rau 4,4′-dimethylbenzophenone.
Cov ntaub ntawv kev nyab xeeb:
Kev nyab xeeb profile ntawm 4,4'-dimethylbenzophenone yog siab, tab sis cov hauv qab no yuav tsum tau sau tseg:
- Nws yuav ua rau khaus rau qhov muag thiab tawv nqaij, yog li ceev faj thaum siv nws.
- Tsis txhob nqus cov plua plav lossis kov nws cov tshuaj kom tsis txhob muaj qhov tsis xis nyob lossis ua xua.
- Tsis txhob sib cuag nrog cov nplaim taws qhib thaum siv, thiab khaws cia kom deb ntawm cov nplaim taws qhib thiab kub siab.
- Siv raws li kev cob qhia kws tshaj lij thiab ua raws li kev coj ua kev nyab xeeb uas cuam tshuam.
