N-METHYL PYRROLIDONE (NMP), Tsarin kwayoyin halitta :C5H9NO, Turanci ：1-Methyl-2-pyrrolidinone, ruwa mai haske mara launi zuwa rawaya, ƙamshi mai ɗanɗanon ammonia, mai narkewa da ruwa a kowane rabo, wanda aka narkar da shi a cikin ethyl ether, acetone, ester, halogenated hydrocarbon, aromatic hydrocarbons da sauran abubuwan narkewa na halitta. Kusan dukkan abubuwan narkewa suna cika cakuda Chemicalbook, wurin tafasa 204℃, wurin walƙiya 91℃, hygmoscopic, kwanciyar hankali na sinadarai, babu tsatsa ga ƙarfe carbon, aluminum, ɗan lalata ga jan ƙarfe. Yana da fa'idodin ƙarancin ɗanko, kwanciyar hankali na sinadarai mai kyau da kwanciyar hankali na zafi, babban polarity, ƙarancin canzawa, da rashin daidaituwa mara iyaka tare da ruwa da sauran abubuwan narkewa na halitta. Wannan samfurin magani ne mai sauƙi, iyakar da aka yarda da ita a cikin iska shine 100PPM.
Kadarorin da kwanciyar hankali:
1. Ruwa mara launi, ɗanɗanon ammonia, ƙarancin guba na wannan samfurin. Ana iya narkewa da ruwa, ana narkewa a cikin mafi yawan sinadarai na halitta kamar ether da acetone. Yana iya narke yawancin sinadarai na halitta da na inorganic, iskar gas ta polar, mahaɗan polymer na halitta da na roba.
2. Sifofin sinadarai: yana da daidaito a cikin maganin tsaka tsaki. Bayan awanni 8 na kashi 4% na maganin sodium hydroxide, kashi 50% ~ 70% na hydrolysis ya faru. Hydrolysis yana faruwa a cikin abubuwan da aka tattara kuma yana samar da aminocyl acid 4-meth. Saboda amsawar tushen cymbal, yana iya samar da ketone ko sulfurboline.
3. Idan akwai sinadarin alkaline catalysts, yana da tasirin olefin, kuma alkylated reaction yana faruwa a matsayi na uku. N-methylporide yana da ƙarancin alkaline kuma yana iya samar da gishiri hydrochloride. Ya samar da wani abu da aka haɗa shi da gishirin ƙarfe mai nauyi, kamar dumamawa da nickel bromide zuwa 150℃, yana samar da NIBR2(C5H9ON)3, da kuma wurin narkewa na 105℃.
Hanyar samarwa:Ana samunsa ta hanyar amsawa daga γ-butthochroditetes da methylemine. Mataki na farko na amsawar shine samar da amine 4-hydroxyl-N-methyl-base don γ-butthlor da methylide, sannan mataki na biyu ya bushe don samar da N-methylpidohone. Ana iya yin amsawar matakai biyu a jere a cikin reactor na bututu. γ-butthole shine 1: 1.15, matsin lamba shine kusan 6MPa, kuma zafin jiki shine 250 ° C. Bayan an kammala amsawar, ana samun samfurin da aka gama ta hanyar distillation mai ƙarfi da decompression. Adadin kuɗin shiga shine 90%. Idan aka samar da kettle anti-ChemicalBook, adadin methylmine shine sau 1.5-2.5 adadin ka'idar, kuma ana amfani da shirye-shiryen dakin gwaje-gwaje a matsayin misali. Daga cikin wutar lantarki ta 500ml, ana ƙara 2mol γ-butterotone da ruwa 4 Moore don a rufe su kuma a dumama su a 280 ° C na tsawon awanni 4. Bayan sanyaya, a saki methamine mai yawa, a tace, a tattara maki na tacewa a zafin 201-202°C, a sami kimanin gram 180 na samfura, kuma kuɗin shiga zai kasance kusan 90%. Yawan amfani da kayan masarufi (kg/g) γ-butthoboretin 980 methyline (40%) 860.
