Macluumaadka Tixraaca
Isticmaal | alaabta ceeriin ee udgoonka iyo midabaynta; Isku-dhafka dabiiciga ah iyo dhexdhexaadiyeyaasha dawooyinka. loo isticmaalo sida dareere, sidoo kale loo isticmaalo in synthesis organic Dhexdhexaadiyaha Fuke daroogada Taishu. synthesis organic. Miraha |
habka wax soo saarka | 1. Ka soo jeeda falcelinta p-bromophenol oo leh dimethyl sulfate. p-bromophenol ayaa lagu milmay milanka sodium hydroxide, la qaboojiyey ka hooseeya 10 °c, ka dibna dimethyl sulfate ayaa si tartiib ah loogu daray walaaqaya. Heerkulka falcelinta waxaa lagu kicin karaa 30 ° C., kuleyl ilaa 40-50 ° C. Oo walaaqaya 2H. Lakabka saliidda waa la kala soocaa, waxaa lagu dhaqaa biyo ilaa dhexdhexaad ah, lagu qallajiyo kaalshiyam chloride anhydrous ah, oo la nadiifiyo si loo helo badeeco dhammaatay. Iyada oo anisole ay tahay walxo cayriin ah, falcelinta bromine-ka ee bromine ee glacial acetic acid ayaa la fuliyay, ugu dambeyntiina waxaa lagu helay dhaqidda iyo nadiifinta cadaadiska hoos u dhaca. p-bromophenol waxaa loo isticmaalaa sida walxo ceeriin ah si ay uga jawaabto dimethyl sulfate ee xalalka alkaline. Maadaama fal-celinta ay tahay exothermic, dimethyl sulfate ayaa si tartiib ah loogu daraa si heerkulka qubeyska falcelinta uu yahay 50 ° C. Ama ka hooseeya. Ka dib marka la dhammeeyo falcelinta, isku darka falcelinta ayaa loo oggolaaday inay istaagto lakabyadana waa la kala saaray. Lakabka dabiiciga ah ayaa la soo saaray oo laga soo saaray ethanol ama diethyl ether. Marxaladda la soo saaray ayaa la nadiifiyey si loo soo celiyo soosaaraha. |
