N-METHYL PYRROLIDONE (NMP), formula ya molekile :C5H9NO, Icyongereza: 1-Methyl-2-pyrrolidinone, ifite amazi adafite ibara cyangwa umuhondo, ifite impumuro nke ya ammonia, ishobora kuvanga n'amazi mu rugero urwo arirwo rwose, ishongeshejwe muri ethyl ether, acetone, ester, halogenated hydrocarbons, aromatic hydrocarbons n'ibindi bintu bivangwa n'ibinyabuzima, hafi ya byose bivangwa n'ibinyabutabire bya Chemicalbook, ubushyuhe bugera kuri 204℃, ubushyuhe bugera kuri 91℃, hygmoscopic, ubuziranenge bw'ibinyabutabire, nta bushyuhe bugera ku cyuma cya karuboni, aluminiyumu, ihinduka buhoro ku muringa. Ifite ibyiza byo kuba ifite ubushyuhe buke, ubuziranenge bwiza bw'ibinyabutabire n'ubushyuhe bugera ku bushyuhe, polarity nyinshi, ubushyuhe buke, no kuba ifite ubushyuhe butagira iherezo hamwe n'amazi n'ibintu byinshi bivangwa n'ibinyabuzima. Iki gicuruzwa ni umuti woroheje, ubunini bwemewe mu kirere ni 100PPM.
Imitungo n'ituze:
1. Amazi adafite ibara, uburyohe bwa ammonia, uburozi buke bw'iki gicuruzwa. Gishobora gushonga mu mazi, kigashonga mu bintu byinshi bya organic nka ether na acetone. Gishobora gushonga ibintu byinshi bya organic n'inorganic, imyuka ya polar, ibintu bya polymer karemano n'ibya sintetike.
2. Imiterere ya shimi: ihamye mu gisubizo kidahinduka. Nyuma y'amasaha 8 yo gukoresha 4% by'umuti wa sodium hydroxide, 50% ~ 70% by'umuti wa hydrolysis wabayeho. Hydrolysis ibaho mu bintu bivanze kandi ikora aside aminocyl ya 4-meth. Bitewe n'uburyo cymbal base ikora, ishobora gukora ketone cyangwa sulfurboline.
3. Mu gihe hari katalysts za alkaline, igira ingaruka za olefin, kandi habaho reaction ya alkylated ku mwanya wa gatatu. N-methylporide ni alkaline nkeya kandi ishobora gukora umunyu hydrochloride. Ikora umunyu uvanze n'icyuma gikomeye, nko gushyushya na bromide ya nickel kugeza kuri 150℃, ikora NIBR2 (C5H9ON)3, n'urugero rwo gushonga rwa 105℃.
Uburyo bwo gukora:Iboneka binyuze mu gukora imyitozo iva kuri γ-butthochroditettes na methylemine. Intambwe ya mbere y'ibikorwa ni ugukora amine ya 4-hydroxyl-N-methyl-base kuri γ-butthlor na methylide, hanyuma intambwe ya kabiri igakurwamo amazi kugira ngo hakorwe N-methylpidohone. Uburyo bw'imikorere bushobora gukorwa mu buryo bukurikiranye muri tube reactor. γ-butthole ni 1: 1.15, umuvuduko ni hafi 6MPa, kandi ubushyuhe ni 250 ° C. Nyuma y'uko imyitozo irangiye, umusaruro urangiye uboneka hakoreshejwe imashini igabanya ubushyuhe n'iyoroheje. Igipimo cy'inyungu ni 90%. Iyo kettle anti-ChemicalBook ikozwe, ingano ya methylmine ni inshuro 1.5-2.5 z'ingano y'imitekerereze, kandi itegurwa rya laboratwari rikoreshwa nk'urugero. Muri 500ml hydropower, 2mol γ-butterone na 4 Moore liquid byongerwaho kugira ngo bifungwe kandi bishyushye bifungwe kuri 280 ° C mu gihe cy'amasaha 4. Nyuma yo gukonjesha, sohora methamine irenze urugero, kuraho ibinyabutabire, kusanya amanota yo gutunganya ibinyabutabire kuri 201-202 ° C, ubone garama 180 z'ibicuruzwa, kandi inyungu izaba hafi 90%. Ibikoresho fatizo bikoreshwa (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Imikorere n'ububiko:
1. Uburyo bwo kubika
Bika munsi y'umwuka wumutse, shyiramo agakoresho gafunze, hanyuma ubibike ahantu hakonje kandi humutse.
2. Ingamba zo kwirinda imikorere
Irinde ko byangirika: Ugomba gushaka ubuyobozi bwihariye mbere yo kubikoresha. Irinde ko byagera ku ruhu no mu maso. Irinde guhumeka umwuka n'umwotsi. Ntukegere aho umuriro uturuka. -Kutanywa itabi. Fata ingamba zo gukumira ko ibintu byiyongera.
3. Uburyo bwo kwirinda kubika ibintu
Hari ahantu hakonje mu bubiko. Bika igikoresho gifunze kandi ubibike ahantu humutse kandi hahumeka umwuka. Ikigo gifunguye kigomba gufungwa neza kandi kigashyirwa ahantu hahagaze kugira ngo hirindwe ko amazi yameneka. Kuraho uburyo bwo kubika amazi bushobora kwangirika bitewe n'ubushuhe.
