2-Pyrrolidinone CAS 616-45-5
ʻO 2-Pyrrolidinone kahi hui heterocyclic i loaʻa ka naikokene a me kahi amide cyclic o ka gamma aminobutyric acid (GABA). Hiki ke hoʻomaopopo ʻia he apo ʻelima lālā (4 mau ʻātoma kalapona a me 1 ʻātoma naikokene) a me kahi hui carbonyl (C=O). ʻO 2-Pyrrolidinone kahi mea hoʻoheheʻe aprotic polar me ke kiko paila kiʻekiʻe, ke kiko hau haʻahaʻa, ka solubility ikaika, ka paʻa wela a me ke kemika maikaʻi loa.

1. A laila ua polymerized ʻia i loko o polyvinylpyrrolidone (PVP) a me polyvinylpyrrolidone (PVPP). Hoʻohana nui ʻia kēia mau polymers ma nā kahua e like me ka lāʻau lapaʻau, ka meaʻai, nā mea hoʻonani, a pēlā aku.
2. I loko o ka ʻoihana uila, ka hopena hoʻohemo photoresist: ʻO 2-Pyrrolidinone kahi ʻāpana koʻikoʻi i hoʻohana ʻia i ke kaʻina hana o nā semiconductors a me nā panela hōʻike e wehe pono a palekana i ka photoresist, he mea nui ia no ka ʻoihana uila hou. Hoʻohana ʻia e hoʻomaikaʻi i ka hana pākaukau a hoʻonui i ka palekana.
3. Hoʻohana ʻia nā mea hoʻomaʻemaʻe ʻoihana a me nā mea hoʻohemo pena, me ko lākou solubility ikaika, e hoʻomākaukau i nā mea hoʻomaʻemaʻe ʻoihana holomua, ʻoi aku hoʻi no ka wehe ʻana i nā resins paʻakikī, nā ʻīnika, nā uhi, a pēlā aku.
4. Hoʻohana ʻia ka ʻīnika a me nā uhi ʻana, ma ke ʻano he mau mea hoʻoheheʻe holomua, no nā ʻīnika kūikawā (e like me ka ʻīnika inkjet) a me nā uhi ʻana, e hāʻawi ana i ka pae maikaʻi a me ke kūpaʻa.
1. Ka hoʻoheheʻe ʻia: Hiki ke hui pū ʻia ka 2-Pyrrolidinone me ka hapa nui o nā mea hoʻoheheʻe organik e like me ka wai, nā alcohols, nā ethers, nā esters, nā hydrocarbons chlorinated, a me nā hydrocarbons aromatic, a he mea hoʻoheheʻe "honua".
2. Nā kūpaʻa kino: Kiʻekiʻe ka paila kiʻekiʻe (245 ° C), haʻahaʻa ka hau hau (-23 ° C), kiʻekiʻe ka lapalapa ahi (129 ° C), kūpaʻa wela maikaʻi.
3. Nā waiwai kemika: He hana nā waiwai kemika, a hiki i kāna mau pilina NH a me C=O ke komo i nā hopena like ʻole.
4. Ka hoʻoheheʻe ikaika loa: Hiki ke hoʻoheheʻe i nā polymers like ʻole, nā resins, nā dyes, a me nā paʻakai inorganic, me nā ʻano noi like ʻole.
