Kev siv:Dimethylamide (DMF) yog ib qho tseem ceeb ntawm cov khoom siv raw khoom thiab cov kuab tshuaj ua haujlwm siab, feem ntau yog siv hauv kev lag luam xws li polyurethane, acrylic, tshuaj, tshuaj tua kab, dyes, electronics, thiab lwm yam. siv nyob rau hauv zus tau tej cov ntub hluavtaws tawv;Raws li cov tshuaj hluavtaws intermediate hauv kev lag luam kws tshuaj, nws tau siv dav hauv kev tsim cov tshuaj doxycycline, cortisone, thiab sulfonamide;Raws li cov kuab tshuaj hauv kev lag luam acrylic fiber ntau, nws yog tsuas yog siv rau qhuav spinning zus tau tej cov acrylic fibers;Siv nyob rau hauv kev lag luam tshuaj tua kab los ua ke kom muaj txiaj ntsig zoo thiab tsis muaj tshuaj lom tshuaj tua kab tshuaj tua kab;Siv los ua cov kuab tshuaj zas xim hauv kev lag luam dye;quenching ntawm tinned Cheebtsam thiab tu ntawm Circuit Court boards nyob rau hauv lub electronics kev lag luam;Lwm cov kev lag luam muaj xws li cov khoom siv phom sij, cov kuab tshuaj rau cov tshuaj crystallization, adhesives, thiab lwm yam.

Lub npe tshuaj: N, N-dimethylacetamide

Dimethylacetamide yog ib tug muaj zog polar non protonated hnyav uas muaj peev xwm yaj ntau lub tebchaw thiab yog kiag li miscible nrog dej, ethers, ketones, esters, thiab lwm yam. Nws muaj thermal stability, tsis tshua muaj hydrolysis tsis kam, tsis tshua muaj corrosion, thiab tsawg toxicity.Nws muaj zoo solubility rau ntau yam resins, tshwj xeeb tshaj yog polyurethane resin thiab polyimide resin, thiab yuav siv tau raws li ib tug hnyav rau tshav kub-resistant hluavtaws fibers, yas films, coatings, tshuaj, thiab acrylonitrile spinning.Dimethylacetamide, raws li qhov tsis tshua muaj toxicity, kub kub taw tes, thiab siab polarity uas tsis yog proton hnyav thiab tshuaj nruab nrab, yog siv dav hauv cov khoom siv hluavtaws, tshuaj, tshuaj tua kab, tshuaj fibers, roj av ua, thiab cov organic pigments.

Dab tsi yog qhov tseem ceeb ntawm dimethyl formamide?

01siv los ua cov tshuaj analytical reagent thiab hnyav rau ethylene resin thiab acetylene

02yog ib qho zoo heev organic hnyav siv los ua hnyav rau polyurethane, polyacrylonitrile, thiab polyvinyl chloride, nrog rau cov khoom siv raw rau extractants, tshuaj, thiab tshuaj tua kab xws li imidacloprid.

03Dimethylformamide tsis yog tsuas yog siv cov khoom siv tshuaj lom neeg, tab sis kuj yog ib qho hnyav hnyav nrog ntau yam kev siv.Dimethylformamide yog cov kuab tshuaj zoo rau ntau yam polymers siab xws li polyethylene, polyvinyl chloride, polyacrylonitrile, polyamide, thiab lwm yam. Nws tuaj yeem siv rau ntub spinning ntawm hluavtaws fibers xws li polyacrylonitrile fibers thiab synthesis ntawm polyurethane;Siv rau kev ua yeeb yaj kiab yas;Nws kuj tseem siv tau los ua cov xim pleev xim rau tshem tawm cov xim;Nws tseem tuaj yeem yaj qee cov xim tsis muaj kuab lom, muab cov yam ntxwv ntawm dyes.Dimethylformamide yog siv rau aromatic hydrocarbon extraction, nrog rau kev sib cais thiab rov qab butadiene los ntawm C4 feem thiab isoprene los ntawm C5 feem.Nws kuj tseem siv tau los ua ib qho reagent zoo rau kev sib cais cov khoom tsis yog hydrocarbon los ntawm paraffin.Nws muaj kev xaiv zoo rau kev solubility ntawm isophthalic acid thiab terephthalic acid: solubility ntawm isophthalic acid nyob rau hauv dimethylformamide yog ntau dua li nyob rau hauv terephthalic acid.Cov kuab tshuaj rho tawm lossis ib nrab crystallization hauv dimethylformamide tuaj yeem cais ob.Hauv kev lag luam petrochemical, dimethyl formamide tuaj yeem siv los ua cov pa roj rau kev sib cais thiab ua kom cov pa roj.Hauv cov tshuaj tiv thaiv organic, dimethylformamide tsis yog tsuas yog siv los ua cov kuab tshuaj xwb, tab sis kuj yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis.Nws tuaj yeem siv los tsim chlorpyrifos hauv kev lag luam tshuaj tua kab;Hauv kev lag luam kws tshuaj, nws tuaj yeem siv los tsim cov pyrimidine iodide, doxycycline, cortisone, vitamin B6, iodoside, Qubijing, thiapyrimidine, N-formyl sarcolysin, antineoplastic acid, methoxyaromaine, bianzapine, cyclohexanonefur static, hexazonefuracetic acid gesterone , biliveratrol, chlorpheniramine, thiab lwm yam.Dimethylformamide plays lub luag haujlwm catalytic hauv hydrogenation, dehydrogenation, lub cev qhuav dej, thiab dehalogenation cov tshuaj tiv thaiv, txo cov tshuaj tiv thaiv kub thiab txhim kho cov khoom purity.

04Tsis yog aqueous tov titration reagent, hnyav rau ethylene resin thiab acetylene, organic synthesis, photometry, roj chromatography nyob ruaj khov theem (qhov siab tshaj plaws kev khiav hauj lwm kub 50 ℃, hnyav methanol), sib cais thiab tsom xam ntawm C2-C5 hydrocarbons, thiab muaj peev xwm cais ib txwm, isobutene , cis, thiab trans butene.Tshuaj tua kab residue tsom xam.Organic synthesis.Peptide synthesis.Siv hauv kev lag luam kev yees duab.
