N-METIL PYRROLIDONE (NMP), tātai ngota: C5H9NO, Ingarihi：1-Methyl-2-pyrrolidinone, wai mārama kore tae ki te kōwhai, kakara haukini pakupaku, ka taea te whakaranu ki te wai i roto i tetahi ōwehenga, ka rewa ki te ethyl ether, acetone, ester, hauwaiwaro halogenated, hauwaiwaro kakara me ētahi atu whakarewa waro. Tata ki ngā whakarewa katoa he ranunga Chemicalbook katoa, te ira kohua 204℃, te ira mura 91℃, hygmoscopic, pumau matū, kāore he waikura ki te maitai waro, te konumohe, he waikura pakupaku ki te parahi. He painga ōna ko te matotoru iti, te pumau matū pai me te pumau wera, te polarity teitei, te iti o te hurihuri, me te mutunga kore o te whakaranu ki te wai me te maha o ngā whakarewa waro. He rongoā ngawari tēnei hua, ko te kukū rohe whakaaetia i te hau ko te 100PPM.
Ngā Āhuatanga me te pumau:
1. He wai kore tae, he reka haukini, he iti te paitini o tēnei hua. Ka taea te wairewa ki te wai, ka wairewa ki te nuinga o ngā whakarewa waro pērā i te ether me te acetone. Ka taea e ia te wairewa i te nuinga o ngā matū waro me ngā matū kore-waro, ngā hau porotaka, ngā matū polymer tūturu me ngā matū hangai.
2. Ngā āhuatanga matū: he pumau tonu i roto i te otinga kūpapa. I muri i ngā hāora e 8 o te 4% o te otinga hauwai konutai, ka puta te 50% ~ 70% o te waikura. Ka puta te waikura i roto i ngā mea kukū, ā, ka puta te waikawa aminocyl 4-meth. Nā te tauhohenga o te turanga himipora, ka taea te whakaputa i te ketone, te sulfurboline rānei.
3. I roto i te noho o ngā whakakorikori kawakore, he rite tōna pānga ki te olefin, ā, ka puta he tauhohenga alkylated i te tuatoru o ngā tūranga. He ngoikore te kawakore o te N-methylporide, ā, ka taea e ia te whakaputa i te tote hydrochloride. Ka hangaia he ranunga ki te tote konganuku taumaha, pērā i te whakamahana me te nickel bromide ki te 150℃, ka puta te NIBR2(C5H9ON)3, me te ira rewa o te 105℃.
Tikanga whakaputa:Ka whiwhi mā te tauhohenga mai i ngā γ-butthochroditettes me te methylemine. Ko te taahiraa tuatahi o te tauhohenga ko te whakaputa i te 4-hydroxyl-N-methyl-base amine mō te γ-butthlor me te methylide, ā, ka whakamaroketia te taahiraa tuarua hei whakaputa i te N-methylpidohone. Ka taea te mahi i te tauhohenga e rua-taahiraa i roto i te tauhohenga ngongo. Ko te γ-butthole he 1:1.15, ko te pēhanga he tata ki te 6MPa, ā, ko te pāmahana he 250 °C. I muri i te otinga o te tauhohenga, ka whiwhihia te hua kua oti mā te whakamaroke kukū me te decompression. Ko te reiti whiwhinga he 90%. Mena ka puta te kettle anti-ChemicalBook, ko te nui o te methylmine he 1.5-2.5 ngā wā o te nui o te ariā, ā, ka whakamahia te whakaritenga taiwhanga hei tauira. I roto i te 500ml hydropower, ka tāpirihia te 2mol γ-butterotone me te 4 Moore wai kia katihia, kia whakamahanahia hoki ki te 280 °C mō te 4 hāora. I muri i te whakamatao, tukuna te nui o te methamine, whakahoro, kohia te 201-202 °C ngā pūwāhi whakahoro, whiwhihia te 180g o ngā hua, ā, ko te moni whiwhi me tata ki te 90%. Ko te kai rauemi mata (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Te whakahaere me te rokiroki:
1. Tikanga rokiroki
Penapenahia ki raro i te hau maroke kore mahi, kia hiritia te ipu, ā, rongoatia ki te wāhi hauhautanga, maroke hoki.
2. Ngā whakatūpato whakahaere
Ārai i te pānga: Me tiki he aratohu motuhake i mua i te whakamahinga. Ārai i te pa ki te kiri me ngā kanohi. Ārai i te manawa i te kohu me te paowa. Kaua e whakatata ki te pūtake o te ahi. -Kaua e momi hikareti. Me mahi i ngā mahi hei ārai i te kohikohinga o te matū paturopi.
3. Ngā mahi whakatūpato mō te rokiroki
He wāhi hauhautanga kei roto i te rokiroki. Puritia te ipu kia katia, ā, rongoatia ki te wāhi maroke, hauhautanga hoki. Me hiritia te ipu tuwhera, me te pupuri i tōna tūranga poutū kia kore ai e turuturu. He mea tairongo ki te haumākū te whakakorenga o te tiaki pupuhi.
