Nhanganyaya
4,4′-Dimethylbenzophenone. Izvi zvinotevera sumo yezvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye4,4'-dimethylbenzophenone:
Hunhu:
4,4′-Dimethylbenzophenone ikristaro isina ruvara yakasimba iyo isinganyanyi kunyungudika mumvura pane tembiricha yekamuri, asi inonyungudika mune organic solvents senge alcohols uye esters.
Zvishandiso: Inogona zvakare kushandiswa seyepakati mune organic synthesis yekubatanidza mamwe makomisheni.
Nzira:
Nzira yekugadzirira inowanzoshandiswa inogadzirirwa nekuita kwebenzophenone uye n-butylformaldehyde pasi pemamiriro e-alkaline. Matanho chaiwo ekugadzirisa anogona kusanganisira chizvarwa chediazonium salts yeketoni kana oxime, iyo yakaderedzwa kusvika ku4,4'-dimethylbenzophenone.
Zvekuchengetedza
Iyo yekuchengetedza mbiri ye4,4'-dimethylbenzophenone yakakwirira, asi zvinotevera zvinofanirwa kucherechedzwa:
- Inogona kutsamwisa maziso neganda, saka tora matanho ekuzvidzivirira paunenge uchiishandisa.
- Dzivisa kufema guruva kana kubata mhinduro yayo kudzivirira kusagadzikana kana allergic reaction.
- Dzivisa kusangana nemoto wakavhurika panguva yekushandiswa, uye chengetedza kure nemoto wakavhurika uye tembiricha yakakwira.
-Shandisa pasi pehutungamiriri hwehunyanzvi uye tevera maitiro akakodzera ekuchengetedza.
