Ulwazi Lwereferensi
| Sebenzisa | izinto zokusetshenziswa zamakha namadayi; I-Organic synthesis kanye ne-intermediate yemithi. isetshenziswa njenge-solvent, ibuye isetshenziswe ku-organic synthesis I-intermediate ye-Fuke drug Taishu. i-organic synthesis. I-solvent. |
| indlela yokukhiqiza | 1. Itholakala ekuphenduleni kwe-p-bromophenol nge-dimethyl sulfate. I-p-bromophenol yahlakazwa kusixazululo se-sodium hydroxide encibilikisiwe, yapholiswa yaba ngaphansi kuka-10 °c, kwase kuthi i-dimethyl sulfate yengezwa kancane kancane ngokushukumisa. Izinga lokushisa lokusabela lingakhushulwa libe ngu-30 ° C., lishisiswe libe ngu-40-50 ° C. Futhi lishukunyiswe ku-2H. Ungqimba lwamafutha luhlukaniswa, lugezwe ngamanzi kuze kube yilapho lungathathi hlangothi, lomiswe nge-anhydrous calcium chloride, futhi luhlanjululwe ukuze kutholwe umkhiqizo ophelile. Nge-anisole njengempahla eluhlaza, ukusabela kwe-bromine nge-bromine ku-glacial acetic acid kwenziwa, futhi ekugcineni kwatholakala ngokuwashwa nokukhishwa kwe-distillation ngaphansi kwengcindezi encishisiwe. I-p-bromophenol isetshenziswa njengento eluhlaza ukuze isabele nge-dimethyl sulfate kusixazululo se-alkali. Njengoba ukusabela kuyi-exothermic, i-dimethyl sulfate yengezwa kancane ukuze izinga lokushisa kubhavu lokusabela libe ngu-50 ° C. Noma liphansi. Ngemva kokuphothulwa kokusabela, ingxube yokusabela yavunyelwa ukuma futhi izendlalelo zihlukaniswe. I-organic layer yakhishwa futhi yakhishwa nge-ethanol noma i-diethyl ether. Isigaba esikhishiwe sihlanjululwe ukuze kubuyiselwe i-extractant. |
| isigaba | izinto ezinobuthi |
| ubuthi grade | ubuthi |
| Ubuthi obunamandla | I-oral-mouse LD50: 2200 mg / kg; I-Intraperitoneal-mouse LD50: 1186 mg/kg |
| izici eziyingozi ezivuthayo | ovuthayo elangabini elivulekile; Intuthu ye-bromide enobuthi evela ekushisweni |
| isitoreji kanye nezici zokuthutha | Indawo yokugcina impahla ingena umoya futhi yomiswe ekushiseni okuphansi, isitoreji esihlukile sezithasiselo zokudla |
| i-ejenti yokucisha | i-carbon dioxide, igwebu, isihlabathi, inkungu yamanzi. |
