N-METHYL PYRROLIDONE(NMP), molecular formula :C5H9NO, English：1-Methyl-2-pyrrolidinone, kala ole a melemele ka wai alohilohi, ʻala iki ka amonia, hiki ke hoʻoheheʻe ʻia me ka wai i kēlā me kēia ʻāpana, hoʻoheheʻe ʻia i loko o ka ethyl ether, acetone, ester, halogenated hydrocarbon, aromatic hydrocarbons a me nā mea kūlohelohe ʻē aʻe. ʻO nā mea hoʻoheheʻe, ʻaneʻane hoʻopiha nā mea hoʻoheheʻe a pau i ka hui ʻana o Chemicalbook, kahi e hoʻolapalapa ai 204 ℃, kiko uila 91 ℃, hygmoscopic, paʻa kemika, ʻaʻohe ʻino i ke kila kalapona, aluminika, ʻino iki i ke keleawe.Loaʻa iā ia nā pōmaikaʻi o ka viscosity haʻahaʻa, ke kūpaʻa kemika maikaʻi a me ke kūpaʻa wela, ka polarity kiʻekiʻe, ka haʻahaʻa haʻahaʻa, a me ka miscibility pau ʻole me ka wai a me nā mea hoʻoheheʻe organik he nui.He lāʻau maʻalahi kēia huahana, ʻo ka palena palena ʻae ʻia i ka lewa he 100PPM.
Waiwai a me ke kūpaʻa:
1. ʻO ka wai kala ʻole, ʻono ammonia, haʻahaʻa haʻahaʻa o kēia huahana.Hiki ke hoʻoheheʻe ʻia me ka wai, hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe organik e like me ka ether a me ka acetone.Hiki iā ia ke hoʻoheheʻe i ka hapa nui o nā pūhui organik a me nā mea ʻole, nā kinoea polar, nā pūhui polymer kūlohelohe a me ka synthetic.
2. Nā waiwai kemika: ʻano paʻa i ka hoʻonā kū ʻole.Ma hope o 8 mau hola o 4% o ka sodium hydroxide solution, 50% ~ 70% o ka hydrolysis.Hana ʻia ka hydrolysis i loko o nā concentrates a hoʻopuka i ka 4-meth aminocyl acid.Ma muli o ka hopena o ke kumu kimebala, hiki iā ia ke hana i ka ketone a i ʻole sulfurboline.
3. I ka noho ana o ka alkaline catalysts, loaʻa iā ia ka hopena o kahi olefin, a loaʻa ka hopena alkylated ma ke kolu o ka wahi.ʻO ka N-methylporide he alkaline nāwaliwali a hiki ke hoʻohua i ka paʻakai hydrochloride.Hoʻohui ʻia me ka paʻakai metala kaumaha, e like me ka hoʻomehana ʻana me ka nickel bromide i 150 ℃, e hana ana i ka NIBR2(C5H9ON)3, a me kahi helu heheʻe o 105 ℃.
Hana hana:Loaʻa ia ma ka hopena mai γ-butthochroditettes a me methylemine.ʻO ka hana mua o ka pane ʻana, ʻo ia ka hoʻohua ʻana i ka 4-hydroxyl-N-methyl-base amine no ka γ-butthlor a me ka methylide, a laila hoʻomaʻemaʻe ʻia ka lua e hoʻohua ai i ka N-methylpidohone.Hiki ke hana ʻia ka hopena ʻelua-ʻanuʻu i ka lālani i loko o ka pahu reactor.ʻO ka γ-butthole ka 1: 1.15, ʻo ke kaomi ma kahi o 6MPa, a ʻo ka mahana he 250 ° C. Ma hope o ka pau ʻana o ka hopena, loaʻa ka huahana i hoʻopau ʻia e ka concentrated a me ka decompression distillation.ʻO 90% ka loaʻa kālā.Inā hoʻopuka ʻia ka puke anti-ChemicalBook, ʻo ka nui o ka methylmine he 1.5-2.5 manawa ka nui o ka theoretical, a ua hoʻohana ʻia ka hoʻomākaukau ʻana i ke keʻena.Ma waena o ka 500ml hydropower, 2mol γ-butterotone a me 4 Moore wai i hoʻohui ʻia e pani ʻia a hoʻopaʻa ʻia i ka 280 ° C no 4h.Ma hope o ka hoʻoluʻu, hoʻokuʻu i ka methamine kiʻekiʻe, distillation, e hōʻiliʻili i nā helu distillation 201-202 ° C, loaʻa ma kahi o 180g o nā huahana, a ʻo ka loaʻa kālā ma kahi o 90%.Ka hoʻohana ʻana i nā mea maka (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Ka hana a me ka mālama ʻana:
1. Keʻano mālama
E kūʻai ma lalo o ke kinoea maloʻo maloʻo, e hoʻopaʻa paʻa i ka pahu, a waiho i kahi maloʻo a maloʻo.
2. Nā hana mālama
Hōʻalo i ka ʻike: Pono ʻoe e loaʻa i ke alakaʻi kūikawā ma mua o ka hoʻohana ʻana.Hōʻalo i ka pili ʻana me ka ʻili a me nā maka.E pale i ka inhalation o ka mahu a me ka uahi.Mai hoʻokokoke i ke kumu o ke ahi.-ʻAʻole puhi paka.E hana i nā hana e pale ai i ka hoʻonui ʻana.
3. Nā mālama mālama
Aia kahi wahi ʻoluʻolu i ka waiho ʻana.E pani i ka pahu a waiho i kahi maloʻo a me ka makani.Pono e hoʻopaʻa pono ʻia ka pahu hāmama a mālama i ke kūlana kūpaʻa e pale ai i ka leakage.Hoʻopau ʻia ka mālama ʻana i ka inflatable i ka haʻahaʻa.
