He whakarewa rauropi nui te N-methylpyrrolidone (NMP) me te whānuitanga o ngā tono, ā, he mahi nui tana i roto i ngā mara maha. Ko ngā whakamahinga matua o te N-methylpyrrolidone e whai ake nei:

Mara hiko:
Ko te NMP tētahi o ngā whakarewa nui mō te hanga taputapu hiko pēnei i ngā haurua-ā-ira, ngā ara iahiko whakauru, me ngā whakaaturanga tioata wai.
Ka taea e ia te whakarewa i ngā rauemi hikohiko pēnei i ngā konganuku, ngā waikura, me ngā pūmua mō ngā tukanga whakakikorua, whakairo, me te horoi.
I roto i te umanga hikohiko moroiti, ka whakamahia te NMP i roto i ngā mara teitei pēnei i te tioata wai, ngā haurua-ā-ira, me ngā papa ara iahiko.

Marae hauora:
E whakamahia ana te NMP i roto i te umanga rongoā mō te whakarite i ngā rongoā hangai me ngā takawaenga rongoā, pērā i ētahi rongoā ārai huaketo me ngā rongoā ārai-puku.
He teitei ngā whakaritenga haumaru mō te NMP karaehe rongoā, ā, e whakamahia whānuitia ana i roto i te rongoā, ngā rongoā whakapūmau, ngā rongoā kararehe, me ngā takawaenga rongoā.

Ngā mara matū me ētahi atu mara ahumahi:
Ka taea te whakamahi i te NMP hei whakarewa mō ngā tauhohenga polymerization, ā, e whakamahia ana hoki hei hanga rauemi polymer pērā i ngā kirihou hangarau pērā i ngā polyamides, ngā polyimides, me te polyphenylene sulfide.
Ka whakamahia hoki hei waimeha, hei whakarewa hoki mō ngā hua pēnei i ngā peita, waituhi, me ngā piripiri.
I roto i te umanga matū hinu, ka whakamahia te NMP mō te kukū o te acetylene, te whakakorenga o te hau hanga, te whakamahine hinu whakahinuhinu, me ētahi atu. Hei tāpiritanga ki ngā patu pepeke, ka whakapai ake i te wairewa me te marara o ngā patu pepeke. Ka whakamahia hoki te NMP i roto i ngā rauemi whakamahana, ngā tae, ngā kaihoko horoi ahumahi, me ētahi atu. Umanga pākahiko lithium: Ko te NMP he whakarewa pito-mua mō ngā pākahiko lithium me te whakarewa tautoko mō ngā here hiko pai o te pākahiko lithium. Ngā mara rangahau me te tātari: Ka whakamahia hoki te NMP hei wāhanga neke, hei electrolyte rānei i roto i ngā whakamātautau pēnei i te chromatography wai me te electrophoresis. Hei whakarāpopototanga, he whānuitia ngā tono a te N-methylpyrrolidone i roto i ngā hikohiko, rongoā, matū, pākahiko lithium, rangahau me te tātari, me ētahi atu nā ōna āhuatanga ā-tinana me te matū ahurei.
