Gabatarwa
3,4-Dimethylbenzophenone, kuma aka sani da ketocarbonate ko Benzoin. Mai zuwa shine bayanin yanayinsa, amfaninsa, shirye-shiryensa da bayanan aminci:
Hali:
-Bayyana: 3,4-Dimethylbenzophenone wani farin crystalline ne mai ƙarfi.
-Solubility: Yana kusan rashin narkewa a cikin ruwa, kuma yana da babban solubility a cikin kaushi na kwayoyin halitta kamar ethanol da dimethylformamide.
-Ma'anar narkewa: Matsayin narkewa na 3,4-dimethylbenzophenone yana kusan 132-134 digiri Celsius.
Properties: Yana da wani electrophilic reagent wanda zai iya shiga cikin daban-daban halayen kamar hydrogen bond samuwar, hadawan abu da iskar shaka-rage dauki tsakanin ketone carbon da methyl.
Amfani:
- 3,4-Dimethyl benzophenone aka yafi amfani da matsayin reagent ga Organic kira halayen.
Ana iya amfani da shi azaman reagent na electrophilic don shiga cikin haɓakar haɓakar electrophilic, samuwar ketone carbonate da sauran halayen.
- Hakanan za'a iya amfani dashi azaman na'urar daukar hoto don lithography, warkar da haske da sauran filayen.
Hanyar Shiri:
Ɗayan hanya don shirye-shiryen -3,4-dimethyl benzophenone shine haɗuwa da barone. Matakan halayen sune kamar haka: Na farko, styrene yana amsawa tare da wuce haddi na bromine a karkashin haske ko hasken ultraviolet don samar da β-bromostyrene. Ana mayar da β-bromostyrene tare da hydroxide (misali, NaOH) don samar da 3,4-dimethylbenzophenone.
-Wani hanyar shiri shine amsa acetophenone da sodium bromide a ƙarƙashin yanayin alkaline don samar da 3,4-dimethyl benzophenone.
Bayanin Tsaro:
- 3,4-Dimethylbenzophenone ba shi da guba.
-A guji saduwa da fata da shakar numfashi yayin amfani.
-Ruyi waje da fata, yakamata a wanke da ruwa mai yawa.
-Idan an shaka, a matsa nan da nan zuwa wuri mai kyau.
-Ana ba da shawarar sanya safofin hannu masu kariya da na'urorin numfashi masu dacewa yayin aiki.
-Lokacin da ake amfani da shi da adanawa, da fatan za a bi ka'idodin aiki masu aminci kuma sanya shi cikin abin da yara ba za su iya isa ba.
