N-methylacetamide ili mu mawonekedwe a makhiristo oyera ngati singano kapena madzi owonekera opanda mtundu. Kapangidwe kake kamatha kusiyana malinga ndi kutentha, kuthamanga kwa magazi ndi zina.

Kapangidwe ka thupi: Fomula ya molekyulu ya N-methylacetamide ndi C3H7NO, ndipo kulemera kwa molekyulu ndi 73.09. Malo ake osungunuka nthawi zambiri amakhala pakati pa 26-28°C, ndipo malo ake owira ndi 204~206°C. Ili ndi madzi osungunuka bwino komanso kuchuluka kwa 0.9571 pa 25°C. Kuphatikiza apo, malo ake owunikira ndi 108°C, zomwe zikusonyeza kuti chinthucho chikhoza kuyaka kutentha kwambiri.
Kapangidwe ka mankhwala ndi ntchito zake: N-methylacetamide ndi yokhazikika pa mankhwala, siiwonongeka mosavuta, ndipo imatha kusungunula mankhwala ena. Nthawi zambiri imagwiritsidwa ntchito ngati chosungunulira chachilengedwe ndipo ingagwiritsidwe ntchito ngati chosinthira pakati pa kapangidwe ka zinthu zachilengedwe monga mankhwala ophera tizilombo ndi mankhwala. Mu makampani opanga mankhwala, N-methylacetamide ndi chinthu chofala kwambiri chomwe chimagwiritsidwa ntchito popanga mamolekyu a mankhwala otchedwa cephalosporins.

Mwachidule, N-methylacetamide makamaka imakhala ngati makhiristo oyera ngati singano kapena madzi owonekera opanda mtundu. Ili ndi zinthu zosiyanasiyana zakuthupi komanso zamakemikolo ndipo imagwiritsidwa ntchito kwambiri popanga zinthu zachilengedwe komanso kupanga mankhwala.

Kugwiritsa ntchito N-methylacetamide

Chosungunulira chachilengedwe: N-methylacetamide ndi madzi opanda mtundu komanso owonekera bwino kutentha kwa chipinda ndi kupanikizika. Amasungunuka bwino m'madzi ndipo ndi chosungunulira chachilengedwe chokhala ndi kukhazikika kwa mankhwala. Sikophweka kuwola ndipo amatha kusungunula mitundu yosiyanasiyana ya mankhwala. Amagwiritsidwa ntchito kwambiri mu organic synthesis chemistry.

Kuphatikizika kwachilengedwe: N-methylacetamide ndi chinthu chofunikira kwambiri chophatikizika kwachilengedwe. Chimatha kutenga nawo mbali pazinthu zosiyanasiyana zachilengedwe monga alkylation, hydroxylation, ndi phosphation, ndipo chimapereka zinthu zofunika kwambiri popanga mankhwala ophera tizilombo, mankhwala, ndi zina zotero.

Zipangizo zopangira mankhwala: Mu makampani opanga mankhwala, N-methylacetamide ndi chinthu chofala chomwe chimagwiritsidwa ntchito popanga maantibayotiki a cephalosporin. Mtundu uwu wa maantibayotiki uli ndi mphamvu yopha mabakiteriya komanso mphamvu yopha mabakiteriya, ndipo umagwiritsidwa ntchito kwambiri m'machitidwe azachipatala.

Mwachidule, N-methylacetamide imagwira ntchito yofunika kwambiri mu organic solvents, organic synthesis intermediates, ndi zopangira mankhwala.
