3 4-Dimethylbenzophenone (CAS# 2571-39-3)

Okwu mmalite

3,4-Dimethylbenzophenone, nke a makwaara dị ka ketocarbonate ma ọ bụ Benzoin. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:

Ọdịdị:

-ọdịdị: 3,4-Dimethylbenzophenone bụ kristal ọcha siri ike.

-Solubility: Ọ fọrọ nke nta ka ọ ghara ịsọpụ na mmiri, ma nwee nnukwu solubility na ihe mgbaze organic dị ka ethanol na dimethylformamide.

-Mgbaze: Ebe mgbaze nke 3,4-dimethylbenzophenone bụ ihe dịka 132-134 degrees Celsius.

Njirimara kemịkalụ: Ọ bụ reagent electrophilic nke nwere ike isonye na mmeghachi omume dị iche iche dị ka njikọ njikọ hydrogen, mmeghachi omume mbelata oxidation n'etiti ketone carbon na methyl.

Jiri:

- 3,4-Dimethyl benzophenone na-bụ-eji dị ka a reagent maka organic njikọ mmeghachi omume.

Enwere ike iji ya dị ka onye na-ahụ maka electrophilic iji sonye na mmeghachi omume mgbakwunye electrophilic, nhazi carbonate ketone na mmeghachi omume ndị ọzọ.

-Enwekwara ike iji ya dị ka fotosentizer maka lithography, ọgwụgwọ ọkụ na mpaghara ndị ọzọ.

Ụzọ nkwadebe:

Otu usoro maka nkwadebe nke -3,4-dimethyl benzophenone bụ mmeghachi omume nke barone. Nzọụkwụ nke mmeghachi omume bụ ndị a: Nke mbụ, a na-emeghachi styrene na ngafe bromine n'okpuru ìhè ma ọ bụ ultraviolet ìhè iji mepụta β-bromostyrene. A na-emeghachi β-bromostyrene na hydroxide (dịka ọmụmaatụ, NaOH) iji mepụta 3,4-dimethylbenzophenone.

Usoro nkwadebe ọzọ bụ imeghachi omume acetophenone na sodium bromide n'okpuru ọnọdụ alkaline iji mepụta 3,4-dimethyl benzophenone.

Ozi nchekwa:

- 3,4-Dimethylbenzophenone bụ obere egbu egbu.

- Zere kọntaktị akpụkpọ ahụ na iku ume mgbe ị na-eji.

-Ruyi mpụga kọntaktị na akpụkpọ, kwesịrị ozugbo itucha na ọtụtụ mmiri.

-Ọ bụrụ na ikuru ume, kwaga ozugbo gaa n'ebe ikuku dị mma.

-A na-atụ aro iyi uwe nchebe kwesịrị ekwesị na ngwa iku ume mgbe ị na-arụ ọrụ.

-Mgbe ị na-eji ma na-echekwa, biko soro usoro arụ ọrụ nke ọma ma debe ya n'ebe ụmụaka enweghị ike.
