N-Methyl pyrrodidone (NMP), Molecular Formula: C5H9no, Chirungu: Sol Solvent, dzinenge dzese solventes yakazara kemikari Sanganisa, BOLIL PONT 204 Iyo ine zvakanakira viscosity yakaderera, kugadzikana kwemakemikari akanaka uye kugadzikana kwekunyora, polarity yakakwira, yakaderera, uye isingaenzaniswi nemvura nemvura uye yakawanda organic sol sol. Ichi chigadzirwa chinodhaka zvinyoro, iyo inobvumirwa muganho wekusangana mumhepo ndeye 100ppm.
Zvivakwa uye kugadzikana:
1. Isina ruvara mvura, Ammonia flavour, yakaderera utsi hweichi chigadzirwa. Inogona kuve yakanyarara nemvura, nyura mune yakawanda organic sol soles yakadai seEther uye acetone. Inogona kunyungudika zvakanyanya uye inorganic makomputa, magasi polar, zvakasikwa uye zvakaringana polymer makomputa.
2. Makemikari zvivakwa: yakagadzikana mumhinduro yemagariro. Mushure memasere masere e4% ye sodium hydroxide solution, 50% ~ 70% yeiyo hydrolysis yakaitika. Hydrolysis inowanzoitika mukumanikidza uye inogadzira 4-meth aminocyl acid. Nekuda kwekuita kweiyo cymbal base, inogona kuburitsa ketone kana sulparboline.
3 N-methylporide haina kusimba alkaline uye inogona kuburitsa munyu hydrochloride. Yakaumbwa yakabatanidzwa nemunyu anorema simbi, sekudziya neiyo nickel bromide kusvika ku150 ℃, Gadzira nibr2 (c5h9on) 3, uye inonyungudika ye10 ℃.
Maitiro Ekugadzira:Iyo inowanikwa nekuita kubva ku γ-buthochroditetetette uye methlyemine. Nhanho yekutanga yekuita ndeyekugadzira 4-hydroxyl-n-methyl-base ambel Iyo-nhanho-nhanho yekuita inogona kuitwa mumutsara mune yebhurubhu inogadzirisa. Iyo γ-but kuitwa 1: 1.15, kumanikidzwa kuri pamusoro pe6mpa, uye tembiricha ndeye 250 ° C. Mushure mekunge kuitwa kwapera, chigadzirwa chakapera chinowanikwa nekukasira uye kushomeka kupokana. Chiyero chemari ndeye 90%. Kana iyo ketini anti-kemikosi inogadzirwa, huwandu hwe methylmine ndeye 1.5-.55 times the theoretical huwandu, uye gadziriro yemabharabheti inoshandiswa semuenzaniso. Pakati pe500ml hydropower, 2mol Mushure mekutonhora, kuburitsa yakawandisa methamine, distillation, kuunganidza 201° Contillation mapoinzi, tora 180g yezvigadzirwa, uye mari yacho ichave inenge 90%. Raw zvinyorwa zvekushandisa (kg / g) γ-buttoboretin 980 Methyline (40%) 860.
Kushanda uye Kuchengetedza:
1. Kuchengetedza nzira
Chengetedza pasi peiyo yakaoma syter gasi, chengetedza mudziyo wakasungwa, uye chengetedza munzvimbo inotonhorera uye yakaoma.
2. Kuvhiringidza Zvinotarisirwa
Dzivisa kuoneswa: Iwe unofanirwa kuwana nhungamiro yakakosha usati washandisa. Dzivisa kusangana neganda nemaziso. Dzivisa kuferiswa kwemapuro uye utsi. Usaswedere pedyo nekunobva moto. -Kubva kuputa. Tora matanho ekudzivirira kuunganidzwa kuwanda.
3. Kuchengetedza Kuchengetedza
Kune nzvimbo inotonhorera mukuchengetedza. Chengetedza mudziyo wakavharwa uye chengetedza munzvimbo yakaoma uye yakatsvedza. Midziyo yakavhurika inofanira kunyatsoiswa mucherechedzo uye chengetedza chinzvimbo chekutamira kudzivirira kubhururuka. Kubviswa kwekuchengetedzwa kwehunhu kunonzwisisika kune humidity.
