Nga korero tohutoro

Whakamahi rauemi mata o te kakara me te waikano; Ko te whakahiato pararopi me nga takawaenga rongoa.
whakamahia rite whakarewa, whakamahia hoki i roto i te kōtuitanga organic
Ko te takawaenga o Fuke tarukino Taishu.
whakahiato waro. Wairewa.
tikanga whakaputa 1. I ahu mai i te tauhohenga o te p-bromophenol me te dimethyl sulfate. I rewa te p-bromophenol ki roto i te wairewa konutai waiwai waimeha, i whakamatao ki raro iho i te 10 °c, katahi ka ata taapirihia te dimethyl sulfate me te whakaohooho. Ka taea te whakanui ake i te paanga o te tauhohenga ki te 30 ° C., ka wera ki te 40-50 ° C. Ka whakaohohia mo te 2H. Ka wehea te paparanga hinu, ka horoia ki te wai tae noa ki te noho kore, ka whakamaroke ki te konupūmā pūhaumāota anhydrous, ka māturu kia whiwhi hua kua oti. Ma te anisole hei rauemi mata, ko te tauhohenga bromination me te bromine i roto i te waikawa acetic glacial i mahia, ka mutu ka riro ma te horoi me te whakamaarama i raro i te pehanga iti.
Ka whakamahia te p-bromophenol hei rauemi mata hei tauhohe ki te dimethyl sulfate i roto i te wairewa kawakore. I te mea he exothermic te tauhohenga, ka ata taapirihia te dimethyl sulfate kia 50 ° C te pāmahana i roto i te pati hohenga. I muri i te otinga o te tauhohenga, ka tukuna te ranunga tauhohenga kia tu, ka wehea nga paparanga. Ka tangohia te paparanga waro ki waho, ka tangohia ki te ewaro me te diethyl ether. Ko te wahanga tangohanga i whakamarohia hei whakaora i te tangohanga.
