Indlela yokuvelisa
Ukusuka kwi-salicylaldehyde nge-methylation reaction kunye ne-dimethyl sulfate.Xuba i-3kg ye-sodium hydroxide kwi-30% yomxube omanzi, wongeza i-12.2kg ye-salicylaldehyde kunye ne-80L yamanzi xa uxutywa, kwaye ubushushu bube bubilayo.Yongeza kancinane i-12.9kg ye-dimethyl sulfate, gcina isisombululo se-refluxed malunga ne-3h emva kokuba udibanise, qhubeka u-reflux nge-2-3h elandelayo ye-Chemicalbook, upholise umaleko we-oyile, uhlambe nge-5% yesisombululo se-sodium hydroxide, uze uhlambe ngamanzi ukuya kwi-pH 8. , yongeza i-Anhydrous potassium carbonate yomile.Emva kokucoca i-desiccant, i-distillation phantsi koxinzelelo oluncitshisiweyo, ukuqokelela i-distillate kwi-120 ° C (2.0kPa), eyi-o-methoxybenzaldehyde.I-methylation reaction inokuthi iqhutywe kwi-toluene ye-solvent, kunye nesivuno se-60%.
Injongo
I-Methoxybenzaldehyde yinto ephakathi kwi-organic synthesis, esetyenziselwa ukuveliswa kweziqholo kunye namayeza.I-o-methoxybenformaldehyde ingasetyenziswa kwimveliso.O-Methoxybenzaldehyde ingasetyenziswa ukuvelisa ichiza adrenergic Chuankening.
