Hoʻolauna

ʻO N-Methylacetamide kahi mea hoʻohuihui. He wai waihoʻoluʻu ʻole i hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik he nui i ka lumi wela.

 

Hoʻohana maʻamau ʻia ka N-methylacetamide i ka synthesis organik ma ke ʻano he solvent a me ka waena. Hiki ke hoʻohana ʻia ʻo N-methylacetamide ma ke ʻano he mea hoʻomaʻemaʻe wai, ka mea hoʻokalakupua, a me ka mea hoʻoulu i ka waikawa carboxylic i nā hopena synthesis organik.

 

ʻO ka hoʻomākaukau ʻana o N-methylacetamide hiki ke loaʻa ma ka hopena o ka acetic acid me ka methylamine. ʻO ka ʻanuʻu kikoʻī e hoʻopili i ka waikawa acetic me ka methylamine ma kahi ratio molar o 1: 1 ma lalo o nā kūlana kūpono, a laila hoʻomaʻemaʻe a hoʻomaʻemaʻe e loaʻa ai ka huahana i manaʻo ʻia.

 

ʻIke palekana: Hiki i ka mahu o N-methylacetamide ke hoʻonāukiuki i nā maka a me ka ʻōpū hanu, a he hopena hoʻonāukiuki maʻalahi ke pili me ka ʻili. I ka hoʻohana ʻana a i ʻole ka lawelawe ʻana, pono e lawe ʻia nā hana pale pilikino, e like me ke komo ʻana i nā aniani pale, nā mīkina lima pale, a me nā mea ʻē aʻe. ka hoʻolei pono ʻana i ka ʻōpala. I ka hoʻohana ʻana a me ka mālama ʻana, pono e hahai ʻia nā kaʻina hana palekana kūpono a me nā alakaʻi hana.
