Inkcazo
I-N-Methyl-2-pyrrolidone sisinyibilikisi esingasebenzi kakuhle esineendlela ezahlukeneyo zokusebenza: ukucubungula iikhemikhali, ukugquma umphezulu, iidayi kunye neenxalenye, iikhompawundi zokucoca kwimizi-mveliso nasekhaya, kunye nefomyula yezolimo neyeyeza. Isisithukuthezi esikhulu, kodwa ikwabangele iimeko ezininzi ze-contact dermatitis kwinkampani encinci ye-electrotechnical.

Ukusetyenziswa
Ukusetyenziswa
I-N-Methyl-2-pyrrolidone (NMP) sisinyibilikisi se-polar aprotic esineenzuzo zokuba netyhefu ephantsi, iqondo lokubila eliphezulu, i-solvency ebalaseleyo, ukukhetha okunamandla kunye nozinzo oluhle.
Isetyenziswa kakhulu ekucoceni i-aromatic hydrocarbon extraction, i-acetylene, i-olefins, kunye ne-diolefins.
Isetyenziswa ekucoceni kwimizi-mveliso, kwaye isebenza njengesinyibilikisi sokwenza izibulali-zinambuzane, iiplastiki zobunjineli, iingubo, iifayibha zokwenziwa, kunye neesekethe ezidityanisiweyo.
Ingasetyenziswa njengesicoci semizi-mveliso, isicoci senkunkuma, idayi, i-lubricant kunye ne-antifreeze.
I-N-Methyl-2-pyrrolidone sisinyibilikisi esibalaseleyo, esisetyenziswa kakhulu ekutsaleni i-aromatics, ekucoceni ioyile yokuthambisa, ekuphuculeni i-acetylene, ekuhlukaniseni i-butadiene kunye nasekususeni i-gas sulfurization.
Isetyenziswa ekususeni i-oyile kwi-gesi, ekucoceni ioyile, ekuthambiseni ioyile ekunqandeni i-oyile, ekukhupheni i-olefin, nanjengesinyibilikisi sokwenza i-polymerization yeplastiki yobunjineli enganyibilikiyo.
Ingasetyenziswa kwi-herbicide, ukucoca izixhobo zokukhusela ubushushu, izixhobo zokuchaneka kweshishini le-semiconductor kunye neebhodi zesekethe, ukuphinda kusetyenziswe i-PVC exhaust, njengesepha, isongezelelo sedayi kunye ne-arhente yokusasaza.
Isetyenziswa kwiindawo zokwenza i-polymerization reactions ezifana ne-engineering plastics kunye ne-aramid fiber.
I-N-Methyl-2-pyrrolidone isetyenziswa njenge-polyvinylidene fluoride solvent kunye nezinto ezincedisayo ze-electrode kwiibhetri ze-lithium ion.
