Hoʻolauna

ʻO ka N-ethyl-2-pyrrolidone he wai kala ʻole me kahi ʻala liʻiliʻi. Eia ka wehewehe kikoʻī i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o N-ethyl-2-acetylpyrrole:

 

ʻAno maikaʻi:

- Ke ʻano: ʻO N-ethyl-2-acetylpyrrole kahi wai aniani ʻole.

- Solubility: N-ethyl-2-acetylpyrrole maikaʻi ka solubility i ka wai a me nā ʻano mea hoʻoheheʻe organik.

 

E hoʻohana:

- Solvent: N-ethyl-2-acetylpyrrole he mea hoʻoheheʻe polar maikaʻi loa i hoʻohana nui ʻia i nā ʻoihana kemika, lāʻau lapaʻau, mahiʻai, a me nā ʻoihana uila. Hiki ke hoʻohana ʻia e hoʻoheheʻe i nā mea hoʻohui like ʻole, resins a me nā uhi, a hoʻohana ʻia i ka hoʻokumu ʻana i nā uhi, pena a me nā mea hoʻomaʻemaʻe, etc.

 

Hanana:

Loaʻa pinepine ʻia ka N-ethyl-2-acetylpyrrole ma ka hana ʻana i ka 2-pyrrolidone me ka ethanol. Hiki ke hana i kēia ma ka hana ʻana i ka 2-pyrrolone me ka ethanol me ka hoʻohana ʻana i kahi catalyst alkali ma 250-280 ° C no kekahi mau hola.

 

ʻIke palekana:

- He hopena hoʻonāukiuki ka mahu o N-ethyl-2-acetylpyrrole i ka ʻōnaehana hanu a me nā maka, a hiki i ka pili ʻana me nā maka ke hōʻino. Pono e mālama ʻia e pale aku i ka pili ʻana me ka ʻili a me nā maka ke hoʻohana a lawelawe paha.

- E hoʻohana i nā mea pale pilikino kūpono e like me nā mīkina lima, nā makaaniani palekana, a me nā pale alo ke hoʻohana a lawelawe paha.

- Pono e mālama ʻia ʻo N-ethyl-2-acetylpyrrole ma kahi ʻoluʻolu a maikaʻi hoʻi ka makani, ma kahi mamao mai nā wela kiʻekiʻe a me ke ahi.

- I ka lawelawe ʻana i ka pūhui, e hahai i nā kaʻina hana palekana a hoʻolei pono i ka ʻōpala.
