Cov tshuaj lom neeg yooj yim - N-methylpyrrolidone (NMP)

Lub npe tshuaj: N-methyl-2-pyrrolidone; 1-methyl-2-pyrrolidone; nitrogen-methylpyrrolidone.
CAS TSIS MUAJ.: 872-50-4
Cov mis mos molecular: C5H9NO

Lub npe lus Askiv: N-methyl-2-pyrrolidone
Cov Khoom: N-methylpyrrolidone (NMP luv luv) yog ib qho nitrogen heterocyclic compound nrog cov mis molecular ntawm C5H9NO thiab lub ntsiab lus kub ntawm 204 ° C. Nws yog ib qho kua nrog me ntsis tsw ammonia. Nws yog miscible nrog dej hauv txhua qhov sib piv thiab yog sib xws nrog yuav luag txhua cov kuab tshuaj (ethanol, ethanol, Acetaldehyde, ketones, aromatic hydrocarbons, thiab lwm yam) sib xyaw ua ke.

NMP yog cov kuab tshuaj aprotic polar nrog lub ntsiab lus kub siab, polarity muaj zog, viscosity qis, solubility muaj zog, tsis xeb, tsis muaj tshuaj lom, muaj zog biodegradability, tsis tshua muaj volatility, zoo heev tshuaj stability thiab thermal stability.

Cov txheej txheem tsim khoom: NMP tau raug kev lag luam ntev heev thiab cov thev naus laus zis tau paub tab. Nws cov txheej txheem tsim khoom muaj dehydrogenating 1,4-butanediol (BDO) los tsim γ-butyrolactone (GBL), thiab tom qab ntawd amination ntawm γ-butyrolactone thiab monomethylamine. Cov tshuaj tiv thaiv tsim cov khoom, uas tom qab ntawd distilled thiab purified rau hauv cov khoom tiav NMP.
