Njira Yopangira
Kuchokera ku salicylaldehyde ndi methylation reaction ndi dimethyl sulfate.Sakanizani 3kg ya sodium hydroxide mu 30% yankho lamadzi, onjezerani 12.2kg ya salicylaldehyde ndi 80L yamadzi poyambitsa, ndi kutentha mpaka kuwira.Pang'onopang'ono onjezani 12.9kg wa dimethyl sulfate, sungani yankho la refluxed kwa pafupifupi 3h mutatha kuwonjezera, pitirizani reflux kwa 2-3h kutsatira Chemicalbook, kuziziritsa wosanjikiza mafuta, kusamba ndi 5% sodium hydroxide solution, ndiyeno kusamba ndi madzi pH 8. , kuwonjezera Anhydrous potaziyamu carbonate ndi zouma.Pambuyo pochotsa desiccant, distillation pansi pa kupanikizika kochepa, kusonkhanitsa distillate pa 120 ° C (2.0kPa), yomwe ndi o-methoxybenzaldehyde.The methylation reaction amathanso kuchitidwa mu zosungunulira toluene, ndi zokolola za 60%.
Cholinga
Methoxybenzaldehyde ndi yapakatikati mu kaphatikizidwe ka organic, yomwe imagwiritsidwa ntchito popanga zonunkhira ndi mankhwala.O-methoxybenformaldehyde angagwiritsidwe ntchito popanga.O-Methoxybenzaldehyde angagwiritsidwe ntchito kupanga adrenergic mankhwala Chuankening.
