4-Methylmorpholine N-oxide CAS 7529-22-8
ʻO 4-Methylmorpholine N-oxide (NMMO) solvent he mea hoʻoheheʻe kūikawā a maikaʻi loa me ka solubility ikaika no ka cellulose. He paʻa paʻa a i ʻole ka wai ma ka lumi wela, ʻaʻohe mea ʻawaʻawa, nāwaliwali alkaline, a he hygroscopicity ikaika. Hiki i kēlā me kēia mole ke hoʻopaʻa i nā mole wai. Hiki iā ia ke wehe i ka 120 ℃ a loaʻa i ka hopena overheating a me ka decomposition gasification ma 175 ℃, e lilo i kiʻekiʻe kiʻekiʻe o ka amine oxide.
