Nhanganyaya
Dimethyldione ikemikari ine zita remakemikari methylbenzophenone. Iyi inotevera sumo kune zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza dimetethone:
Hunhu:
-Kutaridzika: isina ruvara kana yakareruka yero inoonekera mvura.
- Solubility: Inonyungudika mumvura, madoro uye ether zvinonyungudutsa.
- Kunhuwa: Nekunhuhwirira kwakakosha.
Shandisa:
- Dimethyldiketone inoshandiswa zvakanyanya mumakemikari synthesis sechinhu chinogadziriswa, chinoderedza mumiririri uye chinokonzera.
- Inogona kushandiswa seyakakosha yepakati mune organic synthesis uye inotora chikamu mukuumbwa kweakasiyana organic komisheni.
Nzira:
- Nzira yekugadzirira inowanzoshandiswa ndeyekuita benzoic acid ne sulfuric acid kana phosphoric acid kuwana benzoyl chloride, uyezve kuita ne methanol uye sodium carbonate kuti uwane dimethyldione.
- Kune dzimwe nzira dzakawanda dzekugadzira dimethyldione, senge chloroformic acid uye phenylisocyanate reaction, ne chloroazobenzene uye protonated dimethylamine reaction, nezvimwe.
Zvekuchengetedza
- Dimethyldiketone isanganiswa yeorganic ine humwe huturu, uye kufumurwa zvakanyanya kana kufema kunogona kukonzera kukanganisa kumuviri wemunhu.
- Methadiketone inofanira kuchengetwa mumudziyo usina mhepo, kure nekupisa uye oxidants.
- Pfeka magurovhosi ekudzivirira uye magirazi paunenge uchishandisa uye kudzivirira kusangana neganda kana maziso.
- Yakakodzera kuchengetedza maitiro ekushanda uye nhungamiro dzinofanirwa kuteverwa mumarabhoritari kana maindasitiri ekugadzira maitiro.
