Kev lag luam Polymer: NMP feem ntau yog siv los ua cov kuab tshuaj hauv kev tsim cov polymers, resins, thiab fibers.
Pharmaceuticals: NMP yog siv rau hauv kev tsim tshuaj, xws li kev tsim tshuaj thiab kev sib txuas.
Agrochemicals: Nws pom daim ntawv thov hauv kev tsim cov tshuaj tua kab thiab tshuaj tua kab.
Xim thiab Txheej: NMP tuaj yeem siv los ua cov kuab tshuaj hauv kev tsim cov xim, txheej, thiab inks.
Roj thiab Gas: Nws yog ua hauj lwm nyob rau hauv lub extraction ntawm roj thiab roj, tshwj xeeb tshaj yog nyob rau hauv kev tshem tawm cov sulfur compounds.
Cov yam ntxwv tshwj xeeb:
Polar Aprotic Solvent: NMP lub ncov qaumteb qabteb thiab aprotic xwm ua rau nws yog ib qho hnyav heev rau ntau yam ntawm polar thiab nonpolar compounds.
High Boiling Point: Nws qhov kub kub kub tso cai rau nws siv rau hauv cov txheej txheem kub tsis muaj evaporating sai.
Kev nyab xeeb thiab kev tswj xyuas kev txiav txim siab:
Kev ceev faj txog kev nyab xeeb yog tsim nyog thaum tuav NMP, suav nrog kev ua pa kom zoo thiab cov khoom siv tiv thaiv, vim nws tuaj yeem nqus tau los ntawm daim tawv nqaij.
Kev ua raws cai, suav nrog kev ua haujlwm noj qab haus huv thiab kev nyab xeeb, yuav tsum ua raws.
