Selelekela
2-Methoxy-3-methylpyrazine (eo hape e tsejoang e le methoxylate) ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa ea eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:
Boleng:
- Ponahalo: Melafenone ha e na 'mala ho isa ho kristale e mosehla e khanyang kapa phofo e kristale.
- Sollubility: Ha e qhibilihe habonolo ka metsing, empa e qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le chloroform.
Sebelisa:
Mokhoa:
Ho na le mekhoa e 'maloa ea ho lokisa melafenone,' me e tloaelehileng e kenyelletsa tse peli tse latelang:
- Synthesis by oxidation reaction: 2-methoxy-3-methylpyridine e sebetsanoa le zinki chloride, ebe e kenngoa ka acid ho fumana methrafenone.
- Synthesis by substitution reaction: Methoxy-3-methylpyridine e sebetsanoa le ntho e 'ngoe (e kang methyl iodide) tlas'a alkali catalysis ho fumana methrenone.
Lintlha tsa Tšireletseho:
- Melafenone ke k'hemik'hale 'me e na le likotsi tse itseng.
- Qoba ho hema lerōle, ho kopana le letlalo le mahlo, le ho thibela ho ja.
- Apara liatlana tse sireletsang le likhalase ho netefatsa moea o motle.
- Litšila li lokela ho lahloa ho latela melao ea tikoloho ea lehae.
