Sharaxaad
N-Methyl-2-pyrrolidone waa dareere aprotic ah oo leh adeegsiyo kala duwan: farsamaynta kiimikada batroolka, dahaarka dusha sare, midabaynta iyo qaybaha, isku-dhafka nadiifinta warshadaha iyo guryaha, iyo qaacidooyinka beeraha iyo dawooyinka. Inta badan waa wax kiciya cuncun, laakiin sidoo kale waxay keentay dhowr kiis oo ah dermatitis xiriir ah oo ku dhaca shirkad yar oo elektaroonik ah.

Isticmaalka
Isticmaalka
N-Methyl-2-pyrrolidone (NMP) waa dareere aprotic ah oo leh faa'iidooyinka sunta yar, dhibic karkaraya oo sareysa, xalal aad u fiican, xulasho xooggan iyo xasillooni wanaagsan.
Waxaa si weyn loogu isticmaalaa nadiifinta soo saarista hydrocarbon-ka udgoon, acetylene, olefins, iyo diolefins.
Waxaa loo isticmaalaa nadiifinta warshadaha, waxayna u adeegtaa sidii dareere loogu talagalay soo saarista sunta cayayaanka, injineernimada balaastikada, dahaarka, fiilooyinka synthetic-ga, iyo wareegyada isku dhafan.
Waxa kale oo loo isticmaali karaa nadiifiye warshadeed, kala firdhiye, rinjiye, saliideeye iyo ka hortagga barafowga.
N-Methyl-2-pyrrolidone waa dareere aad u fiican, oo si weyn loogu isticmaalo soo saarista udgoonka, sifeynta saliidda, kobcinta acetylene, kala soocidda butadiene iyo soo saarista gaaska isku-darka.
Waxaa loo isticmaalaa nadiifinta gaaska, sifeynta saliidda, saliidaynta ka hortagga qabowga, soo saarista olefin, iyo sidii dareere loogu talagalay polymerization-ka balaastigga injineernimada ee aan milmi karin.
Waxaa loo isticmaali karaa sunta cayayaanka, si loo nadiifiyo agabka dahaarka, qalabka saxda ah ee warshadaha semiconductor-ka iyo looxyada wareegga, si dib loogu warshadeeyo qiiqa PVC, sida saabuunta, kabka rinjiga iyo wakiilka kala firdhinta.
Waxaa loo isticmaalaa meelaha loogu talagalay falcelinta polymerization sida injineernimada balaastikada iyo fiber aramid.
N-Methyl-2-pyrrolidone waxaa loo isticmaalaa sidii dareere polyvinylidene fluoride ah iyo qalab kaaliye elektrode ah oo loogu talagalay baytariyada lithium ion.
