Ulwazi lweReference
Sebenzisa | izinto ezikrwada zeziqholo kunye nedayi; I-Organic synthesis kunye ne-pharmaceutical intermediates. isetyenziswa njengenyibilikisi, ikwasetyenziswa kwi-organic synthesis I-intermediate ye-Fuke drug Taishu. organic synthesis. Isinyibilikisi. |
indlela yokuvelisa | 1. Ithathwe kwi-reaction ye-p-bromophenol kunye ne-dimethyl sulfate. I-p-bromophenol yanyibilikiswa kwisisombululo se-sodium hydroxide edibeneyo, yapholiswa ukuya ngaphantsi kwe-10 °c, emva koko i-dimethyl sulfate yongezwa ngokucothayo ngokuvuselela. Ubushushu bokusabela bunokunyuswa ukuya kuma-30 ° C., lufudunyezwe kwi-40-50 ° C. Kwaye luxutywe kwi-2H. Uluhlu lweoli luhlukaniswe, luhlanjwe ngamanzi kuze kube lungathathi hlangothi, lomiswe nge-anhydrous calcium chloride, kwaye ludityaniswe ukuze lufumane umkhiqizo ogqityiweyo. Nge-anisole njengento eluhlaza, ukusabela kwe-bromination kunye ne-bromine kwi-glacial acetic acid yenziwa, kwaye ekugqibeleni yafunyanwa ngokuhlamba kunye ne-distillation phantsi koxinzelelo oluncitshisiweyo. I-p-bromophenol isetyenziswa njengento ekrwada ukusabela nge-dimethyl sulfate kwisisombululo se-alkaline. Ekubeni i-reaction exothermic, i-dimethyl sulfate yongezwa ngokukhawuleza ukuze ubushushu kwibhafu yokusabela yi-50 ° C. Okanye ngaphantsi. Emva kokugqitywa kwempendulo, umxube wokuphendula wavunyelwa ukuba ume kwaye iileyile zahlulwa. I-organic layer ikhutshwe kwaye ikhutshwe nge-ethanol okanye i-diethyl ether. Isigaba esikhutshwayo sachithwa ukuze kubuyiselwe i-extractant. |
