Tikanga Whakaputa
Mai i te salicylaldehyde na te tauhohenga methylation me te dimethyl sulfate.Whakaranuhia te 3kg o te konutai waihā ki roto i te wairewa wai 30%, tāpirihia te 12.2kg o te salicylaldehyde me te 80L o te wai i raro i te whakaoho, me te wera ki te koropupu.Āta tāpirihia te 12.9kg o te dimethyl sulfate, kia mau tonu te otinga tauhohenga kia 3 haora i muri i te taapiri, haere tonu ki te reflux mo te 2-3h i muri mai i te Chemicalbook, whakamatao i te paparanga hinu, horoi ki te 5% wairewa konutai wai, ka horoi ki te wai ki te pH 8 , tāpiri Ka maroke te pāhare pāporo pāhare pāporo anhydrous.I muri i te tātari i te desiccant, te whakamaroke i raro i te pehanga iti, ka kohia te distillate i te 120°C (2.0kPa), he o-methoxybenzaldehyde.Ka taea hoki te kawe i te tauhohenga methylation i roto i te toluene whakarewa, me te hua o te 60%.
Te kaupapa
Ko te Methoxybenzaldehyde he takawaenga i roto i te whakahiato waro, e whakamahia ana mo te hanga o nga mea kakara me nga rongoa.Ka taea te whakamahi i te o-methoxybenformaldehyde ki te hanga.Ka taea te whakamahi O-Methoxybenzaldehyde ki te whakaputa i te tarukino adrenergic Chuankening.
