njira yopanga 1. Kuchokera ku zomwe p-bromophenol ndi dimethyl sulfate. P-bromophenol inasungunuka mu njira yothetsera sodium hydroxide, itakhazikika mpaka pansi pa 10 ° c, ndiyeno dimethyl sulfate inawonjezeredwa pang'onopang'ono ndikugwedeza. Zimene kutentha akhoza kuukitsidwa kwa 30 ° C., usavutike mtima kwa 40-50 ° C. Ndipo analimbikitsa kwa 2H. Mafuta osanjikiza amasiyanitsidwa, kutsukidwa ndi madzi mpaka osalowerera, zouma ndi anhydrous calcium chloride, ndikusungunulidwa kuti mupeze chomaliza. Ndi anisole monga zopangira, bromine reaction ndi bromine mu glacial acetic acid idachitika, ndipo pamapeto pake idapezedwa ndikutsuka ndi kupukutira pansi pamavuto ochepetsedwa.
p-bromophenol imagwiritsidwa ntchito ngati zopangira kuti zigwirizane ndi dimethyl sulfate mu njira ya alkaline. Popeza zomwe zimachitika ndi exothermic, dimethyl sulfate imawonjezedwa pang'onopang'ono kuti kutentha mumadzi osambira ndi 50 ° C. Kapena kutsika. Akamaliza anachita, anachita osakaniza analoledwa kuima ndi zigawo analekanitsidwa. organic wosanjikiza anatengedwa ndi yotengedwa Mowa kapena diethyl ether. The yotengedwa gawo anali distilled kuti achire extractant.
