Metotia Gaosiga
Mai le salicylaldehyde e ala i le tali methylation ma le dimethyl sulfate.Faafefiloi le 3 kilokalama o le sodium hydroxide i totonu o se vaifofo vai e 30%, faaopoopo le 12.2kg o le salicylaldehyde ma le 80L o le vai i lalo o le faʻafefeteina, ma vevela i le faʻafefe.Fa'aopoopo lemu le 12.9kg o le dimethyl sulfate, fa'amama le vaifofo tali mo le tusa o le 3h pe a uma ona fa'aopoopo, fa'aauau le reflux mo le 2-3h mulimuli i le Chemicalbook, fa'amalie le suau'u, fufulu i le 5% sodium hydroxide solution, ona fufulu lea i le vai i le pH 8 , faaopoopo Anhydrous potassium carbonate ua mago.A maeʻa ona faʻamama le faʻamaʻi, faʻamama i lalo o le faʻaitiitia o le mamafa, aoina le faʻamaʻi ile 120 ° C (2.0kPa), o le o-methoxybenzaldehyde.E mafai foi ona faia le tali o le methylation i le toluene solvent, ma le fua o le 60%.
Faamoemoega
Methoxybenzaldehyde o se vaeluagalemu i le organic synthesis, faʻaaogaina i le gaosiga o mea manogi ma vailaʻau.O le o-methoxybenformaldehyde e mafai ona faʻaaogaina i le gaosiga.O-Methoxybenzaldehyde e mafai ona faʻaaogaina e gaosia ai le vailaʻau adrenergic Chuankening.
