N-METHYL PYRROLIDONE (NMP), qaacidada kelli dareerayaasha, Ku dhawaad dhammaan dareerayaasha dhammaystiran isku darka Kiimikada, barta karkarinta 204 ℃, dhibic flash 91 ℃, hygmoscopic, xasiloonida kiimikada, daxalka lahayn birta kaarboonka, aluminium, wax yar udgoon ilaa naxaas.Waxay leedahay faa'iidooyinka viscosity hooseeya, xasilloonida kiimikada wanaagsan iyo xasilloonida kulaylka, polarity sare, isbeddel hoose, iyo micirnimo aan xad lahayn oo leh biyo iyo dareerayaal badan oo dabiici ah.Alaabtani waa daroogo khafiif ah, xaddidaadda xaddidan ee xaddidan ee hawadu waa 100PPM.
Guryaha iyo xasiloonida:
1. Dareere aan midab lahayn, dhadhan ammonia, sunta hoose ee alaabtan.Waxay ku milmi kartaa biyo, ku milmi kara inta badan dareerayaasha organic sida ether iyo acetone.Waxay milmi kartaa inta badan xeryahooda dabiiciga ah iyo kuwa aan noolaha ahayn, gaaska polar, xeryahooda polymer-ka ee dabiiciga ah iyo kuwa-synthetic.
2. Waxyaabaha kiimikaad: ilaa xad deggan oo xal dhexdhexaad ah.Ka dib 8 saacadood oo ah 4% of sodium hydroxide xal, 50% ~ 70% of hydrolysis dhacay.Hydrolysis waxay ku dhacdaa xoog-saarid waxayna abuurtaa 4-meth aminocyl acid.Iyadoo ay ugu wacan tahay falcelinta saldhigga suxuunta, waxay dhalin kartaa ketone ama sulfurboline.
3. Jiritaanka alkaliin-kiciyayaasha, waxay leedahay saamaynta olefin, falcelinta alkylated ayaa ku dhacda kaalinta saddexaad.N-methylporide waa alkaline daciif ah waxayna dhalin kartaa cusbada hydrochloride.Waxa la sameeyay cusbo bir culus ah oo isku dhafan, sida kulaylinta nikkel bromide ilaa 150 ℃, taasoo dhalinaysa NIBR2(C5H9ON) 3, iyo barta dhalaalaysa ee 105℃.
Habka wax soo saarka:Waxaa lagu helaa falcelin ka timid γ-butthochroditettes iyo methylemine.Tallaabada ugu horreysa ee falcelinta waa in la dhaliyo 4-hydroxyl-N-methyl-base amine ee γ-butthlor iyo methylide, iyo tallaabada labaad ayaa markaa fuuqbaxa si loo dhaliyo N-methylpidohone.Falcelinta laba-tallaabo ah ayaa lagu samayn karaa isku xigta ee reactor-ka tuubada.γ-butthole waa 1: 1.15, cadaadisku wuxuu ku saabsan yahay 6MPa, heerkulkuna waa 250 ° C. Ka dib marka falcelinta la dhammeeyo, badeecada la dhammeeyey waxaa lagu helaa xoojinta iyo decompression.Heerka dakhligu waa 90%.Haddii kittle anti-Chemicalbook la soo saaro, xadiga methylmine waa 1.5-2.5 jeer ka badan qiyaasta aragtida, diyaarinta shaybaarka ayaa loo isticmaalaa tusaale ahaan.Waxaa ka mid ah 500ml oo koronto-dhal ah, 2mol γ-butterotone iyo 4 Moore dareere ah ayaa lagu daraa in la xiro oo lagu kululeeyo 280 ° C 4 saac.Ka dib qaboojinta, sii daa methamine xad-dhaaf ah, distillation, ururi 201-202 ° C dhibcood distillation, hel qiyaastii 180g oo badeecooyin ah, dakhliguna wuxuu noqon doonaa ilaa 90%.Isticmaalka alaabta ceeriin (kg/g) γ-butthoboretin 980 methyline (40%) 860.
Hawlgalka iyo kaydinta:
1. Habka kaydinta
Ku kaydi gaaska qallalan hoostiisa, weelka ha xidho, oo ku kaydi meel qabow oo qalalan.
2. Taxaddar hawleedka
Ka fogow soo-gaadhista: Waxaad u baahan tahay inaad hesho hagitaan gaar ah ka hor intaanad isticmaalin.Ka fogow taabashada maqaarka iyo indhaha.Ka fogow neefsashada uumiga iyo qiiqa.Ha u dhowaanin meesha uu dabka ka kacayo.-Sigaar la'aan.Qaado tillaabooyin aad uga hortagayso isu-ururinta taagan.
3. taxadarka kaydinta
Waxaa jira meel qabow oo kaydinta.Weelka ha xidho oo ku kaydi meel engegan oo hawo leh.Weelka furan waa in si taxadar leh loo xiraa oo lagu hayaa booska toosan si looga hortago daadinta.Ciribtirka ilaalinta la buufiyo ayaa xasaasi u ah huurka.
