Igama lekhemikhali: N, N-dimethylacetamide
I-Dimethylacetamide sisinyibilikisi esinamandla se-polar non protonated esinokunyibilikisa iikhompawundi ezahlukeneyo kwaye sixutywa ngokupheleleyo namanzi, ii-ether, ii-ketones, ii-esters, njl. Inokuzinza okuphezulu kobushushu, ukumelana okuphantsi kwe-hydrolysis, ukugqwala okuphantsi, kunye nobuthi obuphantsi. Inokunyibilika okuhle kwiiresini ezahlukeneyo, ngakumbi i-polyurethane resin kunye ne-polyimide resin, kwaye ingasetyenziswa njengesinyibilikisi seefayibha zokwenziwa ezimelana nobushushu, iifilimu zeplastiki, ii-coatings, amayeza, kunye ne-acrylonitrile spinning. I-Dimethylacetamide, njengetyhefu ephantsi, indawo yokubilisa ephezulu, kunye ne-polarity ephezulu ye-non proton solvent kunye ne-chemical intermediate, isetyenziswa kakhulu kwiindawo ezifana nezinto zokwenziwa, amayeza, izibulala-zinambuzane, iifayibha zamakhemikhali, ukucutshungulwa kwepetroleum, kunye nee-pigment ze-organic.
Ziziphi iindlela eziphambili zokusebenzisa i-dimethyl formamide?
01isetyenziswa njenge-reagent yohlalutyo kunye nesinyibilikisi se-ethylene resin kunye ne-acetylene
02sisinyibilikisi esilungileyo se-organic esisetyenziswa njengesinyibilikisi se-polyurethane, i-polyacrylonitrile, kunye ne-polyvinyl chloride, kunye nezinto eziluhlaza kwii-extractants, amayeza, kunye nezibulali-zinambuzane ezifana ne-imidacloprid.
03I-Dimethylformamide ayisiyonto isetyenziswa kakhulu kwikhemikhali kuphela, kodwa ikwayisombululi esibalaseleyo esinokusetyenziswa okubanzi. I-Dimethylformamide sisisombululi esilungileyo kwiipolymers ezahlukeneyo eziphezulu ezifana ne-polyethylene, i-polyvinyl chloride, i-polyacrylonitrile, i-polyamide, njl. Ingasetyenziselwa ukujikeleza okumanzi kweefayibha zokwenziwa ezifana neefayibha ze-polyacrylonitrile kunye nokuhlanganiswa kwe-polyurethane; Isetyenziselwa ukwenza ifilimu yeplastiki; Ingasetyenziswa kwakhona njengesisusi sepeyinti sokususa ipeyinti; Inganyibilikisa neepigment ezithile ezinyibilikayo kancinci, izinike iimpawu zeedayi. I-Dimethylformamide isetyenziselwa ukukhupha i-hydrocarbon enuka kamnandi, kunye nokwahlula nokubuyisela i-butadiene kwi-C4 fraction kunye ne-isoprene kwi-C5 fraction. Ingasetyenziswa kwakhona njenge-reagent esebenzayo yokwahlula izinto ezingezizo ii-hydrocarbon kwi-paraffin. Inokukhetha okuhle kokunyibilika kwe-isophthalic acid kunye ne-terephthalic acid: ukunyibilika kwe-isophthalic acid kwi-dimethylformamide kukhulu kunoko kwi-terephthalic acid. Ukukhupha i-solvent okanye i-crystallization engaphelelanga kwi-dimethylformamide kunokwahlula ezi zinto zimbini. Kwishishini le-petrochemical, i-dimethyl formamide ingasetyenziswa njengento yokufunxa igesi yokwahlula nokucokisa iigesi. Kwi-organic reactions, i-dimethylformamide ayisetyenziswa kakhulu njenge-solvent kuphela, kodwa ikwasetyenziswa njenge-intermediate ebalulekileyo kwi-organic synthesis. Ingasetyenziselwa ukuvelisa i-chlorpyrifos kwishishini le-pesticide; Kwishishini le-pharmaceutical, ingasetyenziselwa ukwenza i-pyrimidine iodide, i-doxycycline, i-cortisone, i-vitamin B6, i-iodoside, i-Qubijing, i-thiapyrimidine, i-N-formyl sarcolysin, i-antineoplastic acid, i-methoxyaromaine, i-bianzapine, i-cyclohexanone nitrourea, i-furfouracil, i-hemostatic acid, i-Fenfenmethasone, i-medroxyprogesterone, i-biliveratrol, i-chlorpheniramine, njl. I-Dimethylformamide idlala indima ye-catalytic kwi-hydrogenation, i-dehydrogenation, i-dehydration, kunye ne-dehalogenation reactions, ukunciphisa ubushushu be-reaction kunye nokuphucula ubumsulwa bemveliso.
04I-reagent ye-titration yesisombululo esingemanzi, i-solvent ye-ethylene resin kunye ne-acetylene, i-organic synthesis, i-photometry, i-gas chromatography stationary phase (ubushushu obuphezulu bokusebenza yi-50 ℃, i-solvent methanol), ukwahlula kunye nohlalutyo lwee-hydrocarbons ze-C2-C5, kunye nokukwazi ukwahlula i-normal, i-isobutene, i-cis, kunye ne-trans butene. Uhlalutyo lwentsalela ye-pesticide. I-organic synthesis. I-peptide synthesis. Isetyenziswa kushishino lweefoto.
