Kugadzira Nzira
Kubva ku salicylaldehyde ne methylation reaction ne dimethyl sulfate.Sanganisa 3kg ye sodium hydroxide muine 30% aqueous solution, wedzera 12.2kg ye salicylaldehyde uye 80L emvura uchikurunga, uye kupisa kusvika kufashaira.Zvishoma nezvishoma wedzera 12.9kg ye dimethyl sulfate, chengetedza mhinduro yakagadziriswa kweinenge 3h mushure mekuwedzera, ramba uchiita reflux kwe2-3h uchitevera Chemicalbook, tonhoresa mafuta layer, geza ne5% sodium hydroxide solution, wogeza nemvura kusvika pH 8. , wedzera Anhydrous potassium carbonate yakaomeswa.Mushure mekusefa kunze kweiyo desiccant, distillation pasi pekumanikidzwa kwakaderedzwa, kuunganidza distillate pa120 ° C (2.0kPa), inova o-methoxybenzaldehyde.Iyo methylation reaction inogona zvakare kuitwa mu solvent toluene, ine goho re60%.
Chinangwa
Methoxybenzaldehyde ndeyepakati mune organic synthesis, inoshandiswa mukugadzirwa kwezvinonhuwira nemishonga.Iyo o-methoxybenformaldehyde inogona kushandiswa mukugadzira.O-Methoxybenzaldehyde inogona kushandiswa kugadzira adrenergic drug Chuankening.
