Cov lus qhia ntxaws ntxaws
N-methyl-2-pyrrolidone (NMP)yog cov kua ntshiab, tsis muaj kob uas muaj ntxhiab tsw me ntsis. Nws yog cov organic compound nrog cov tshuaj mis nyuj C5h9No. NMP yog miscible nrog dej thiab feem ntau cov kuab tshuaj organic, ua rau nws muaj ntau yam hnyav hauv ntau yam kev lag luam.
NMP muaj lub siab npau npau ntawm ib ncig 202-204 ° C (399 ° F) thiab cov vapor qis, uas ua rau nws muaj txiaj ntsig zoo nyob rau hauv cov txheej txheem uas yuav tsum muaj kev ruaj ntseg siab. Nws muaj cov viscosity tsis tshua muaj thiab zoo solvency fais fab, ua rau nws yaj ntau cov khoom siv suav nrog cov polymers, resins, thiab lwm cov ocegic teb.
NMP yog polar zoo heev, ua rau nws yog cov kuab tshuaj zoo heev rau cov khoom noj qab zib polar. Nws muaj lub sijhawm dipole lub sijhawm ntawm 3.78 DEBEYE, uas tso cai rau nws los daws thiab ruaj khov them hom. Cov cuab yeej no ua rau muaj NMP haum rau siv ntau yam tshuaj lom neeg cov tshuaj tiv thaiv, vim tias nws tuaj yeem pab txhawb kev sib cais thiab cov tshuaj tiv thaiv.
Nws yog ib qho tseem ceeb kom nco ntsoov tias NMP muaj qee qhov kev noj qab haus huv thiab kev nyab xeeb. Nws tuaj yeem nqus tau los ntawm daim tawv nqaij thiab nqus tau ntawm nws cov vapors yuav ua rau nws khaus rau lub tshuab ua pa. Lub sijhawm ntev lossis rov ua dua raug rau NMP yuav muaj kev cuam tshuam tsis zoo rau kev muaj peev xwm thiab kev txhim kho ntawm cov menyuam hauv cev xeeb tub.
