1. I-solvent egqwesileyo, isetyenziswe ngokubanzi njenge-extractant ye-aromatics extraction, i-lubricating oil refining, i-acetylene concentration, i-syngas desulfurization, njl., kwaye isetyenziselwa ukucocwa kwemizi-mveliso, njl.
2. I-N-methylpyrrolidone yi-solvent egqwesileyo yokukhupha. Isetyenziswa ngokubanzi njenge-extractant kwinkqubo ye-aromatics extraction, i-acetylene concentration, i-butadiene yokwahlula kunye ne-synthesis gas desulfurization. Kwakhona i-pesticide, iplastiki yobunjineli, i-Solvents kwimveliso yeengubo, ii-synthetic fibers, iisekethe ezidibeneyo, njl. i-LD50 yomlomo yeempuku yi-7ml/kg.
3. Isetyenziswe ngokubanzi kwi-high-grade lubricating oil refining, i-polymer synthesis, izinto ezikhuselayo, i-pesticides, ii-pigments kunye nee-agent zokucoca, njl.
4. Isinyibilikisi. I-Organic Synthesis.
5. Isetyenziswe kwi-aromatics extraction, ukuhlanjululwa kwe-acetylene, i-olefin, kunye ne-diolefin; isetyenziswe kwi-polymer solvent kunye ne-polymerization medium, njengeeplastiki zobunjineli ezifana ne-polyamide, i-polyimide, i-polyphenylene sulfide, kunye ne-aramid fiber Isetyenziswe njenge-solvent kunye ne-extractant. I-NMP sisinyibilikisi se-aprotic ye-polar enetyhefu ephantsi, indawo yokubilisa ephezulu, ukunyibilika okugqwesileyo, ukukhetha okunamandla kunye nokuzinza okulungileyo. Isetyenziswa ngokubanzi kwi-extraction ye-aromatics; ukuhlanjululwa kwe-acetylene, i-olefins kunye ne-diolefins. Ikwasetyenziselwa izinyibilikisi zepolymer kunye nemidiya yepolymerization. Njenge polyamide, polyimide, polyphenylene sulfide kunye nezinye iiplastiki zobunjineli kunye nemicu ye-aramid. Ikwasetyenziswa kwizinto zokugquma, izibulali zinambuzane, ii-pigments kunye nezicoci.
