N-METHYL PYRROLIDONE (NMP), ʻano molekala: C5H9NO, Pelekania: 1-Methyl-2-pyrrolidinone, wai aniani ʻole a melemele, ʻala iki ka ammonia, hui pū me ka wai ma kekahi ʻano, hoʻoheheʻe ʻia i loko o ka ethyl ether, acetone, ester, hydrocarbon halogenated, hydrocarbons ʻala a me nā mea hoʻoheheʻe organik ʻē aʻe, ʻAneʻane pau nā mea hoʻoheheʻe i ka hui Chemicalbook, kiko paila 204 ℃, kiko flash 91 ℃, hygmoscopic, kūpaʻa kemika, ʻaʻohe pala i ke kila kalapona, alumini, ʻānai iki i ke keleawe. Loaʻa iā ia nā pono o ka viscosity haʻahaʻa, kūpaʻa kemika maikaʻi a me ke kūpaʻa wela, polarity kiʻekiʻe, volatility haʻahaʻa, a me ka hui pū ʻole me ka wai a me nā mea hoʻoheheʻe organik he nui. He lāʻau lapaʻau akahai kēia huahana, ʻo ka palena palena i ʻae ʻia i ka lewa he 100PPM.
Nā Waiwai a me ke kūpaʻa:
1. Wai kala ʻole, ʻono ammonia, haʻahaʻa ka ʻawahia 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 hui organik a me nā inorganic, nā kinoea polar, nā hui polymer kūlohelohe a me synthetic.
2. Nā waiwai kemika: paʻa iki i ka hopena kūlike ʻole. Ma hope o 8 mau hola o 4% o ka hopena sodium hydroxide, ua hana ʻia he 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 cymbal, hiki iā ia ke hoʻopuka i ka ketone a i ʻole sulfurboline.
3. I ke ola ʻana o nā mea hoʻouluulu alkaline, loaʻa iā ia ka hopena o kahi olefin, a loaʻa kahi hopena alkylated ma ke kolu o kahi. He alkaline nāwaliwali ʻo N-methylporide a hiki ke hoʻoulu i ka hydrochloride paʻakai. Hoʻokumu ʻia kahi i hoʻohui ʻia me ka paʻakai metala kaumaha, e like me ka hoʻomehana ʻana me ka nickel bromide a i 150 ℃, e hoʻoulu ana iā NIBR2 (C5H9ON) 3, a me kahi kiko heheʻe o 105 ℃.
ʻAno hana:Loaʻa ia ma o ka hopena mai nā γ-butthochroditettes a me ka methylemine. ʻO ka hana mua o ka hopena, ʻo ia ka hana ʻana i ka 4-hydroxyl-N-methyl-base amine no γ-butthlor a me methylide, a laila hoʻomaloʻo ʻia ka lua o ka hana e hana iā N-methylpidohone. Hiki ke hana ʻia ka hopena ʻelua-ʻanuʻu ma ka lālani i loko o ka reactor tube. ʻO ka γ-butthole he 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 ma o ka distillation i hoʻopaʻa ʻia a me ka decompression. ʻO ka helu loaʻa kālā he 90%. Inā hana ʻia ka kettle anti-ChemicalBook, ʻo ka nui o ka methylmine he 1.5-2.5 mau manawa o ka nui theoretical, a hoʻohana ʻia ka hoʻomākaukau ʻana o ka hale hana ma ke ʻano he laʻana. Ma waena o ka hydropower 500ml, ua hoʻohui ʻia ka 2mol γ-butterotone a me 4 Moore wai e pani ʻia a hoʻomehana ʻia ma 280 ° C no 4h. Ma hope o ka hoʻomaʻalili ʻana, e hoʻokuʻu i ka methamine nui, distillation, e hōʻiliʻili i nā kiko distillation 201-202 ° C, e kiʻi i kahi 180g o nā huahana, a ʻo ka loaʻa kālā ma kahi o 90%. ʻO ka hoʻohana ʻana i nā mea maka (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Ka hana a me ka mālama ʻana:
1. Ke ʻano mālama
E mālama ma lalo o ke kinoea inert maloʻo, e hoʻopaʻa pono i ka ipu, a mālama i kahi maloʻo a me kahi anuanu.
2. Nā hana palekana
E pale i ka hoʻopili ʻana: Pono ʻoe e kiʻi i ke alakaʻi kūikawā ma mua o ka hoʻohana ʻana. E pale i ka pili ʻana me ka ʻili a me nā maka. E pale i ka hanu ʻana i ka mahu a me ka uahi. Mai hoʻokokoke aku i ke kumu o ke ahi. -Mai puhi paka. E hana i nā hana e pale aku ai i ka hōʻiliʻili ʻana o ka static.
3. Nā hana palekana no ka mālama ʻana
Aia kahi wahi anuanu i loko o ka waihona. E pani i ka ipu a mālama i kahi maloʻo a me ka ea. Pono e sila pono ʻia ka ipu hāmama a mālama i ke kūlana kū pololei e pale aku i ka liki ʻana. ʻO ka hoʻopau ʻana i ka mālama ʻana i ka inflatable he mea maʻalahi ia i ka haʻahaʻa.
