Mawu Oyamba
Dimethyldione ndi mankhwala omwe ali ndi dzina la mankhwala methylbenzophenone. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha dimetethone:
Ubwino:
- Maonekedwe: Madzi opanda mtundu kapena achikasu owoneka bwino.
- Kusungunuka: Kusungunuka m'madzi, ma alcohols ndi zosungunulira za ether.
- Fungo: Ndi fungo labwino lapadera.
Gwiritsani ntchito:
- Dimethyldiketone imagwiritsidwa ntchito kwambiri popanga mankhwala monga zosungunulira, zochepetsera komanso chothandizira.
- Itha kugwiritsidwa ntchito ngati gawo lapakati pakupanga organic ndikuchita nawo kaphatikizidwe kamitundu yosiyanasiyana.
Njira:
- Njira yokonzekera yomwe imagwiritsidwa ntchito nthawi zambiri ndikuchitapo benzoic acid ndi sulfuric acid kapena phosphoric acid kuti mupeze benzoyl chloride, ndiyeno kuchitapo kanthu ndi methanol ndi sodium carbonate kuti mupeze dimethyldione.
- Pali njira zina zambiri zokonzekera dimethyldione, monga chloroformic acid ndi phenylisocyanate reaction, ndi chloroazobenzene ndi protonated dimethylamine reaction, etc.
Zambiri Zachitetezo:
- Dimethyldiketone ndi organic pawiri yokhala ndi kawopsedwe kena, ndipo kuwonekera kwambiri kapena kutulutsa mpweya kumatha kuwononga thupi la munthu.
- Methadiketone iyenera kusungidwa mu chidebe chotchinga mpweya, kutali ndi kuyatsa ndi okosijeni.
- Valani magolovesi oteteza ndi magalasi mukamagwiritsa ntchito ndikupewa kukhudzana ndi khungu kapena maso.
- Njira zoyendetsera chitetezo ndi malangizo oyenera kutsatiridwa mu labotale kapena kupanga mafakitale.
