| hana hana | 1. No ka hopena o ka p-bromophenol me ka dimethyl sulfate. Ua hoʻoheheʻe ʻia ka p-bromophenol i loko o ka dilute sodium hydroxide solution, hoʻoluʻu i lalo o 10 °c, a laila hoʻohui mālie ʻia ka dimethyl sulfate me ka hoʻoulu ʻana. Hiki ke hoʻokiʻekiʻeʻia ka mahana hopena i 30 ° C., hoʻomehanaʻia i 40-50 ° C. A hoʻouluʻia no 2H. Hoʻokaʻawale ʻia ka ʻaila ʻaila, holoi ʻia me ka wai a hiki i ke kū ʻole, hoʻomaloʻo ʻia me ka calcium chloride anhydrous, a hoʻomaʻemaʻe ʻia no ka loaʻa ʻana o kahi huahana. Me ka anisole e like me ka mea maka, ua hoʻokō ʻia ka hopena bromination me ka bromine i loko o ka waikawa acetic glacial, a i ka hopena ua loaʻa ma ka holoi ʻana a me ka distillation ma lalo o ke kaomi hoʻemi. Hoʻohana ʻia ka p-bromophenol ma ke ʻano he mea maka e hana me ka dimethyl sulfate i loko o kahi hopena alkaline. No ka mea he exothermic ka hopena, ua hoʻohui mālie ʻia ka dimethyl sulfate i 50 ° C ka mahana o ka ʻauʻau ʻauʻau. Ma hope o ka pau ʻana o ka hopena, ʻae ʻia ka hui ʻana e kū a hoʻokaʻawale ʻia nā papa. Lawe ʻia ka papa organik a unuhi ʻia me ka ethanol a i ʻole diethyl ether.
