organic synthesis. Solvent.
kugadzira nzira 1. Yakatorwa kubva pakuita kwep-bromophenol ne dimethyl sulfate. Iyo p-bromophenol yakanyungudutswa mune dilute sodium hydroxide solution, yakanyoroveswa kusvika pasi pe10 ° c, uye ipapo dimethyl sulfate yakawedzerwa zvishoma nezvishoma nekukurudzira. The reaction tembiricha inogona kusimudzwa kusvika 30 ° C., inopisa kusvika 40-50 ° C. Uye yakamutswa 2H. Oiri yemafuta inoparadzaniswa, yakashambidzwa nemvura kusvikira isingarereki, yakaomeswa neanhydrous calcium chloride, uye yakasvibiswa kuti iwane chigadzirwa chakapedzwa. Iine anisole seyakagadzirwa, iyo bromination reaction nebromine muglacial acetic acid yakaitwa, uye pakupedzisira yakawanikwa nekugezwa uye distillation pasi pekumanikidzwa kwakaderedzwa.
p-bromophenol inoshandiswa seyakagadziriswa kuita ne dimethyl sulfate mune alkaline mhinduro. Sezvo maitiro acho ari exothermic, dimethyl sulfate inowedzerwa zvishoma nezvishoma kuitira kuti tembiricha mubhati yekugezera iri 50 ° C. Kana kuderera. Mushure mekupedzwa kwekuita, musanganiswa wekuita wakabvumirwa kumira uye zvidimbu zvakaparadzaniswa. Iyo organic layer yakatorwa uye yakatorwa ne ethanol kana diethyl ether. Chikamu chakabviswa chakanyungudutswa kuti chidzose chinobvisa.
