N-methylpyrrolidone (NMP) bụ ihe dị mkpa na-agbaze ihe ndị sitere n'okike nke nwere ọtụtụ ojiji, na-arụ ọrụ dị mkpa n'ọtụtụ ubi. Ihe ndị a bụ isi ojiji nke N-methylpyrrolidone:

Ngalaba eletrọnịkị:
NMP bụ otu n'ime ihe mgbaze dị mkpa maka imepụta ngwaọrụ eletrọniki dịka semiconductor, sekit agbakọtara, na ngosipụta kristal mmiri mmiri.
Ọ nwere ike ịgbari ihe ndị na-arụ ọrụ eletrọniki dịka ọla, oxides, na polima maka electroplating, etching, na cleaning systems.
N'ime ụlọ ọrụ microelectronics, a na-eji NMP eme ihe n'ọhịa dị elu dịka kristal mmiri mmiri, semiconductors, na bọọdụ sekit.

Ngalaba ahụike:
A na-eji NMP eme ihe n'ụlọ ọrụ ọgwụ maka ịkwadebe ọgwụ sịntetik na ọgwụ ndị na-eme ka mmadụ nwee ike ịgwọ ọrịa, dịka ụfọdụ ọgwụ nje na ọgwụ mgbochi etuto.
NMP nke ọkwa ọgwụ nwere ihe nchekwa dị elu ma a na-ejikarị ya eme ihe na ọgwụ, ọgwụ, ọgwụ anụmanụ, na ọgwụ ndị ọzọ.

Ngalaba kemịkalụ na ụlọ ọrụ ndị ọzọ:
Enwere ike iji NMP mee ihe dị ka ihe mgbaze maka mmeghachi omume polymerization ma ejiri ya mee ihe iji mepụta ihe polymer dị ka plastik injinia dịka polyamides, polyimides, na polyphenylene sulfide.
A na-ejikwa ya dị ka ihe na-agbaze ihe na ihe mgbaze maka ngwaahịa dịka agba, ink, na ihe nrapado.
N'ụlọ ọrụ petrochemical, a na-eji NMP eme ihe maka ịchịkọta acetylene, imepụta gas synthesis, ime ka mmanụ dị ọcha, wdg. Dịka ihe na-enye ọgwụ ahụhụ, ọ na-eme ka ọ dịkwuo mma ịgbaze na ịgbasa nke ọgwụ nje. A na-ejikwa NMP eme ihe na ihe mkpuchi, agba, ihe nhicha ụlọ ọrụ, wdg. Ụlọ ọrụ batrị Lithium: NMP bụ ihe mgbaze ihu maka batrị lithium na ihe mgbaze nkwado maka ihe njikọ electrode batrị lithium dị mma. Ngalaba nyocha na nyocha: A na-ejikwa NMP dị ka usoro mkpanaka ma ọ bụ electrolyte na nnwale dịka mmiri mmiri chromatography na electrophoresis. Na nchịkọta, N-methylpyrrolidone nwere ọtụtụ ojiji na eletrọniki, ọgwụ, kemịkalụ, batrị lithium, nyocha na nyocha, wdg. n'ihi ihe pụrụ iche ya na ihe kemịkalụ ya.
