Hoʻolauna
ʻO Acetone aldehyde dimethanol, i ʻike ʻia hoʻi he acetone methanol. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka acetone aldehyde dimethanol:
ʻAno maikaʻi:
ʻO ka Acetone aldehyde dimethanol he wai ʻole a melemele me ka ʻala ʻala. He mea hoʻohuihui ia i hiki ke hoʻoheheʻe ʻia i ka wai, nā waiʻona, a me nā ethers. ʻAʻole paʻa ka Acetone aldoldehyde methanol, maʻalahi ka hydrolyzed a me ka oxidized, pono e mālama ʻia i kahi anuanu a me ka pouli, a mālama ʻia mai ka oxygen, wela a me nā kumu hoʻāla.
E hoʻohana:
Hoʻohana pinepine ʻia ʻo Acetone aldoldehyde dimethanol ma ke ʻano he waena i ka synthesis organik. Hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā esters, ethers, amides, polymers, a me kekahi mau pūhui organik. Hoʻohana pū ʻia ʻo Pyrudaldehyde methanol ma ke ʻano he mea hoʻoheheʻe, pulu a me nā mea hoʻohui i loko o nā ʻoihana uhi a me nā plastics.
Hanana:
Nui nā ala e hoʻomākaukau ai i ka acetone aldehyde dimethanol. Loaʻa kahi ala maʻamau e ka hopena condensation o ka methanol me ka acetone. I ka hoʻomākaukau ʻana, ua hui pū ʻia ka methanol a me ka acetone ma kahi ratio molar a hoʻoneʻe ʻia i mua o kahi catalyst acidic, ʻo ia ka mea e pono ai ka hoʻomehana ʻana i ka hui ʻana. Ma hope o ka pau ʻana o ka hopena, loaʻa ka acetone aldoldehyde dimethanol maʻemaʻe e ka distillation, crystallization a i ʻole nā ʻano hoʻokaʻawale ʻē aʻe.
ʻIke palekana:
ʻO ka Acetone aldoldemic methanol kahi mea hoʻonāukiuki a pono e pale ʻia i ka hoʻopili pololei ʻana me ka ʻili, nā maka, a me nā membrane mucous. Pono e hoʻokō ʻia ka ventila maikaʻi i ka wā o ka hana, a pono e hoʻohana ʻia nā mīkina lima pale a me nā goggles. I ka lawelawe ʻana a me ka mālama ʻana, pono e hoʻopaʻa ʻia ka pahu mai ka wela, ka ʻā a me nā mea ʻona. Inā komo a inhaled, e ʻimi koke i ka lāʻau lapaʻau.
