Indlela Yokukhiqiza
Kusuka ku-salicylaldehyde ngokusabela kwe-methylation nge-dimethyl sulfate.Xuba u-3kg we-sodium hydroxide ibe yisisombululo esinamanzi esingu-30%, engeza u-12.2kg we-salicylaldehyde kanye no-80L wamanzi ngaphansi kokunyakaziswa, bese ushisa ekubiliseni.Kancane kancane engeza u-12.9kg we-dimethyl sulfate, gcina ikhambi le-refluxed cishe amahora amathathu ngemva kokwengeza, qhubeka u-reflux amahora angu-2-3 kulandela i-Chemicalbook, pholisa ungqimba lwamafutha, geza nge-5% ye-sodium hydroxide solution, bese ugeza ngamanzi ku-pH 8. , engeza i-Anhydrous potassium carbonate yomile.Ngemva kokuhlunga i-desiccant, i-distillation ngaphansi kwengcindezi encishisiwe, ukuqoqa i-distillate ku-120 ° C (2.0kPa), okuyi-o-methoxybenzaldehyde.Ukusabela kwe-methylation kungenziwa futhi ku-toluene ye-solvent, ngesivuno esingu-60%.
Inhloso
I-Methoxybenzaldehyde iwumsebenzi ophakathi nendawo ku-organic synthesis, esetshenziswa ekukhiqizeni izinongo nemithi.I-o-methoxybenformaldehyde ingasetshenziswa ekukhiqizeni.I-O-Methoxybenzaldehyde ingasetshenziswa ukukhiqiza isidakamizwa se-adrenergic Chuankening.
