Hoʻolauna
ʻO Dimethyldione kahi mea kemika me ka inoa kemika methylbenzophenone. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka dimetethone:
ʻAno maikaʻi:
- Ke ʻano: ʻAʻole waihoʻoluʻu a i ʻole melemele māmā wai aniani.
- Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, nā waiʻona a me nā solvents ether.
- Aʻala: Me kahi ʻala ʻono kūikawā.
E hoʻohana:
- Hoʻohana nui ʻia ʻo Dimethyldiketone i ka synthesis kemika ma ke ʻano he mea hoʻoheheʻe, hōʻemi a me ka catalyst.
- Hiki ke hoʻohana ʻia ma ke ʻano he koʻikoʻi koʻikoʻi i ka synthesis organik a komo i ka synthesis o nā ʻano mea like ʻole.
Hanana:
- ʻO ke ʻano hoʻomākaukau maʻamau ka hoʻopili ʻana i ka waikawa benzoic me ka sulfuric acid a i ʻole ka waikawa phosphoric e loaʻa ai ka benzoyl chloride, a laila e hana me ka methanol a me ka sodium carbonate e loaʻa ai ka dimethyldione.
- Nui nā ala ʻē aʻe e hoʻomākaukau ai i ka dimethyldione, e like me ka chloroformic acid a me ka phenylisocyanate reaction, e ka chloroazobenzene a me ka protonated dimethylamine reaction, etc.
ʻIke palekana:
- ʻO ka Dimethyldiketone kahi mea hoʻohuihui me nā mea ʻawaʻawa, a ʻo ka hoʻolaha nui ʻana a i ʻole ka inhalation hiki ke hōʻeha i ke kino o ke kanaka.
- Pono e mālama ʻia ka Methadiketone i loko o kahi pahu paʻa i ka ea, ma kahi mamao aku i ka ʻā a me nā mea oxidants.
- E hoʻohana i nā mīkina lima pale a me nā maka aniani i ka wā e hoʻohana ai a pale i ka pili ʻana me ka ʻili a i ʻole nā maka.
- Pono e hahai ʻia nā kaʻina hana palekana a me nā alakaʻi i loko o nā kaʻina hana hoʻokolohua a i ʻole nā hana hana ʻenehana.
