1.It o se solvent sili ona lelei, faʻaaogaina lautele e avea o se extractant mo le manogi manogi, lubricating suauu faamamaina, acetylene concentration, syngas desulfurization, ma isi, ma faʻaaogaina foi i fale gaosi oloa, ma isi.

2.N-methylpyrrolidone o se mea e sili ona lelei le faʻaaogaina.O loʻo faʻaaogaina lautele e avea o se mea faʻapipiʻi i le faagasologa o le faʻaaogaina o mea manogi, faʻaogaina o le acetylene, vavaeeseina o le butadiene ma le faʻaogaina o le kasa desulfurization.Ose vaila'au fa'atosina, palasitika fa'ainisinia, ma fa'apipi'i tusi vaila'au.Solvents i le gaosiga o meafaitino, filo faʻapipiʻi, fesoʻotaʻiga tuʻufaʻatasia, ma isi mea, e mafai foi ona faʻaaogaina e pei o mea faʻatau oloa, dispersants, vali, lubricants ma antifreezes.O le oloa e maualalo le oona, ma o le gutu LD50 mo isumu e 7ml/kg.

3.Widely faʻaaogaina i le faʻamamaina o le suauʻu lubricating maualuga, polymer synthesis, mea faʻapipiʻi, vailaau faʻasaina, pigments ma mea faʻamamā, ma isi.

4. Solvent.Fa'asoa fa'aletino.

5. Faʻaaogaina i le faʻaaogaina o mea manogi, faʻamamaina o le acetylene, olefin, ma le diolefin;fa'aaogaina i le polymer solvent ma le polymerization medium, e pei o palasitika inisinia e pei ole polyamide, polyimide, polyphenylene sulfide, ma le aramid fiber

6. Faʻaaogaina e avea o se solvent ma extractant.NMP o se solvent polar aprotic ma le maualalo oona, maualuga le vevela, solubility mataʻina, filifili malosi ma mautu lelei.E masani ona faʻaaogaina i le mauaina o mea manogi;fa'amamāina o le acetylene, olefins, ma le lua olefini Tusi Fa'ama'i.E faʻaaogaina foi mo polymer solvents ma polymerization media.E pei o le polyamide, polyimide, polyphenylene sulfide ma isi palasitika inisinia ma alava aramid.E fa'aaogaina fo'i i mea e fa'amama ai, vaila'au fa'ato'aga, pigments ma fa'amama.
