Raupapa matū taketake–N-methylpyrrolidone (NMP)

Ingoa matū: N-methyl-2-pyrrolidone; 1-methyl-2-pyrrolidone; hauota-methylpyrrolidone.
Nama CAS: 872-50-4
Tātai ngota: C5H9NO

Ingoa Ingarihi: N-methyl-2-pyrrolidone
Ngā Āhuatanga: Ko te N-methylpyrrolidone (NMP) he matū hauota heterocyclic me te tauira ngota o C5H9NO me te pāmahana koropupū o te 204°C. He wai he kakara haukini pakupaku. Ka taea te whakaranu ki te wai i roto i ngā ōwehenga katoa, ā, ka hototahi ki te nuinga o ngā whakarewa (ethanol, ethanol, Acetaldehyde, ketones, hydrocarbons kakara, me ētahi atu) kua whakaranua katoatia.

He whakarewa aprotic porotaka te NMP, he teitei te kohua, he kaha te porotaka, he iti te matotoru, he kaha te wairewa, he kore-waikura, he iti te paitini, he kaha te pirau koiora, he iti te hurihuri, he tino pumau te matū me te pumau wera.

Te tukanga whakaputa: Kua roa te NMP e whakamahia ana hei ahumahi, ā, kua pakari te hangarau. Ko tōna tukanga whakaputa ko te tango i te hauwai i te 1,4-butanediol (BDO) hei whakaputa i te γ-butyrolactone (GBL), kātahi ka whakakotahi i te γ-butyrolactone me te monomethylamine. Ka puta ngā hua i te tauhohenga, ka whakahoroa, ka purea hei hua kua oti te hanga, arā, ko te NMP.
