N-METHYL PYRROLIDONE (NMP), chilinganizo cha maselo :C5H9NO, Chingerezi:1-Methyl-2-pyrrolidinone, madzi opanda mtundu mpaka achikasu owonekera, fungo la ammonia pang'ono, osakanikirana ndi madzi mumtundu uliwonse, amasungunuka mu ethyl ether, acetone, ester, halogenated hydrocarbon, ma hydrocarbon onunkhira ndi zina organic zosungunulira, Pafupifupi zosungunulira zonse Chemicalbook mix, otentha mfundo 204 ℃, kung'anima mfundo 91 ℃, hygmoscopic, chemical bata, palibe dzimbiri ku carbon zitsulo, zotayidwa, zowononga pang'ono mkuwa.Zili ndi ubwino wa kukhuthala kochepa, kukhazikika kwa mankhwala ndi kukhazikika kwa kutentha, polarity yapamwamba, kusinthasintha kochepa, ndi kusokonezeka kosawerengeka ndi madzi ndi zosungunulira zambiri za organic.Izi ndi mankhwala ofatsa, malire ovomerezeka mlengalenga ndi 100PPM.
Katundu ndi kukhazikika:
1. Madzi opanda mtundu, kukoma kwa ammonia, kawopsedwe kakang'ono ka mankhwalawa.Ikhoza kusungunuka ndi madzi, kusungunuka mu zosungunulira zambiri monga ether ndi acetone.Ikhoza kusungunula zinthu zambiri zakuthupi ndi zachilengedwe, mpweya wa polar, mankhwala achilengedwe komanso opangidwa ndi polima.
2. Chemical katundu: ndi okhazikika mu ndale njira.Pambuyo pa maola 8 a 4% ya sodium hydroxide solution, 50% ~ 70% ya hydrolysis inachitika.Hydrolysis imachitika mokhazikika ndikupanga 4-meth aminocyl acid.Chifukwa cha momwe chinganga chimagwirira ntchito, chimatha kupanga ketone kapena sulfure.
3. Pokhala ndi zopangira zamchere, zimakhala ndi zotsatira za olefin, ndipo alkylated reaction imapezeka m'malo achitatu.N-methylporide ndi yofooka yamchere ndipo imatha kupanga mchere wa hydrochloride.Anapanga chophatikizika ndi mchere wachitsulo cholemera, monga kutentha ndi faifi tambala bromide mpaka 150 ℃, kupanga NIBR2(C5H9ON)3, ndi malo osungunuka a 105 ℃.
Njira yopangira:Imatengedwa ndi zomwe γ-butthochroditettes ndi methylemine.Gawo loyamba la zomwe zimachitika ndikupanga 4-hydroxyl-N-methyl-base amine ya γ-butthlor ndi methylide, ndipo gawo lachiwiri limachotsedwa madzi kuti lipange N-methylpidohone.Awiri masitepe anachita akhoza kuchitidwa mu mzere mu chubu riyakitala.The γ-butthole ndi 1: 1.15, kupanikizika kuli pafupi ndi 6MPa, ndipo kutentha ndi 250 ° C. Pambuyo pomaliza, chotsirizidwacho chimapezedwa ndi distillation yowonongeka ndi decompression.Mtengo wa ndalama ndi 90%.Ngati ketulo ya anti-ChemicalBook imapangidwa, kuchuluka kwa methylmine ndi 1.5-2.5 nthawi zowerengera, ndipo kukonzekera kwa labotale kumagwiritsidwa ntchito monga chitsanzo.Pakati pa 500ml hydropower, 2mol γ-buterotone ndi 4 Moore madzi amawonjezeredwa kuti atseke ndi kutenthedwa kutsekedwa pa 280 ° C kwa 4h.Pambuyo kuzirala, kumasula methamine kwambiri, distillation, kusonkhanitsa 201-202 ° C distillation mfundo, kupeza pafupifupi 180g mankhwala, ndipo ndalama adzakhala pafupifupi 90%.Kugwiritsa ntchito zopangira (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Kugwiritsa ntchito ndi kusunga:
1. Njira yosungira
Sungani pansi pa mpweya wouma wowuma, sungani chidebe chotsekedwa, ndikusunga pamalo ozizira ndi owuma.
2. Njira zodzitetezera
Pewani kuwonekera: Muyenera kupeza malangizo apadera musanagwiritse ntchito.Pewani kukhudzana ndi khungu ndi maso.Pewani kupuma mpweya ndi utsi.Musayandikire gwero la moto.-Musasute.Chitanipo kanthu kuti mupewe kudzikundikira kosasunthika.
3. Kusamala posungira
Pali malo ozizira posungira.Sungani chidebecho chotsekedwa ndikusunga pamalo owuma ndi mpweya wabwino.Chidebe chotseguka chiyenera kutsekedwa mosamala ndikusunga choyimirira kuti chisatayike.Kuchotsa kusungidwa kwa inflatable kumakhudzidwa ndi chinyezi.
