Habka wax soo saarka
Laga soo bilaabo salicylaldehyde by falcelinta methylation leh dimethyl sulfate.Isku qas 3kg oo sodium hydroxide ah 30% xal aqueous ah, ku dar 12.2kg salicylaldehyde iyo 80L oo biyo ah hoos walaaqda, kulaylkana karkariSi tartiib ah ugu dar 12.9kg oo dimethyl sulfate ah, ku hayso xalalka falcelinta dib u soo noqoshada ilaa 3h ka dib markaad ku darto, sii wad inaad dib u soo celiso 2-3h ka dib buugga Kiimikada, qabooji lakabka saliidda, ku maydh 5% sodium hydroxide xal, ka dibna ku dhaq biyo ilaa pH 8 , ku dar Anhydrous potassium carbonate waa la qalajiyey.Ka dib marka la sifeeyo qalajiyaha, nadiifinta cadaadiska hoos u dhaca, ururinta distillate at 120 ° C (2.0kPa), taas oo ah o-methoxybenzaldehyde.Dareen-celinta methylation-ka ayaa sidoo kale lagu fulin karaa toluene-ka dareeraha ah, oo leh wax-soo-saarka 60%.
Ujeedo
Methoxybenzaldehyde waa dhex dhexaad u ah isku-dhafka dabiiciga ah, oo loo isticmaalo soo saarista xawaashka iyo daawooyinka.O-methoxybenformaldehyde waxaa loo isticmaali karaa wax soo saarka.O-Methoxybenzaldehyde waxaa loo isticmaali karaa in lagu soo saaro daawada adrenergic Chuankening.
