Moʻo kemika kumu–N-methylpyrrolidone (NMP)

Inoa kemika: N-methyl-2-pyrrolidone; 1-methyl-2-pyrrolidone; naikokene-methylpyrrolidone.
Helu CAS: 872-50-4
ʻO ke ʻano molekole: C5H9NO

Inoa Pelekania: N-methyl-2-pyrrolidone
Nā Waiwai: ʻO N-methylpyrrolidone (NMP no ka pōkole) kahi hui nitrogen heterocyclic me kahi ʻano molekala o C5H9NO a me kahi kiko paila o 204 ° C. He wai ia me kahi ʻala ammonia iki. Hiki ke hui pū ʻia me ka wai ma kekahi ʻano a kūpono me ka aneane o nā mea hoʻoheheʻe āpau (ethanol, ethanol, Acetaldehyde, ketones, aromatic hydrocarbons, etc.) i hui piha ʻia.

He mea hoʻoheheʻe aprotic polar ka NMP me ke kiko paila kiʻekiʻe, ka polarity ikaika, ka viscosity haʻahaʻa, ka solubility ikaika, ka non-corrosion, ka toxicity haʻahaʻa, ka biodegradability ikaika, ka volatility haʻahaʻa, ke kūpaʻa kemika maikaʻi loa a me ke kūpaʻa thermal.

Kaʻina hana: Ua lōʻihi ka hoʻomohala ʻia ʻana o NMP a ua oʻo ka ʻenehana. ʻO kāna kaʻina hana e pili ana i ka dehydrogenating 1,4-butanediol (BDO) e hana i ka γ-butyrolactone (GBL), a laila amination o γ-butyrolactone a me monomethylamine. Hoʻopuka ka hopena i nā huahana, a laila hoʻoheheʻe ʻia a hoʻomaʻemaʻe ʻia i loko o ka huahana i hoʻopau ʻia ʻo NMP.

Nā wahi noi

ʻO N-Methylpyrrolidone kahi mea hoʻoheheʻe kiʻekiʻe maikaʻi loa i hoʻohana ʻia i nā petrochemicals, pesticides, nā lāʻau lapaʻau, nā mea uila a me nā ʻoihana ʻē aʻe. Hiki ke hoʻohana ʻia e like me ka acetylene concentration, syngas desulfurization, lubricating oil refining, lubricating oil antifreeze, olefin extraction agent, solvent i loko o ka polymerization o nā plastics engineering insoluble, herbicides mahiʻai, nā mea insulation, integrated circuit production, PVC exhaust gas recovery, cleaning agents, dye auxiliaries, dispersants, etc.
