I-4-Nitrophenetole(CAS#100-29-8)
izinga
Amakristalu aphuzi ngokuphaphathekile. Iphuzu elincibilikayo lingu-60 °C (58 °C), iphoyinti elibilayo lingu-283 °C, 112~115 °C (0.4kPa), futhi ukuminyana okuhlobene ngu-1. 1176. Incibilika kancane emanzini, i-ethanol ebandayo ne-petroleum ebandayo. ether. Incibilika ku-ether, inyibilika ku-ethanol eshisayo ne-ether eshisayo ye-petroleum.
Indlela
Ilungiswa ngokusabela kwe-etherification ye-p-nitrochlorobenzene ne-ethanol. I-P-nitrochlorobenzene ne-ethanol kwengezwe eketelani lokusabela, izinga lokushisa lakhushulelwa ku-82 °C, futhi isisombululo se-ethanol sodium hydroxide sanezelwa kancane, futhi ukusabela kwenziwa ngo-85~88 °C amahora angu-3. I-alkalinity yesisombululo sokusabela yehliswa yaba ngaphansi kuka-0.9%, yapholiswa yaba ngu-75 °C, futhi inani le-pH lalungiswa laba ngu-6.7~7 nge-concentrated hydrochloric acid. Ngemuva kokuma nokuhlelwa kwe-stratification, ungqimba lwamafutha luyathathwa futhi i-sodium nitrophenol igezwa ngamanzi okushisa, futhi ungqimba lwamafutha luhlanjululwa ngaphansi kwengcindezi encishisiwe, futhi ingxenye ye-214 ~ 218 ° C (2. 66 ~ 5.32kPa) ithathwa. njengalo mkhiqizo.
sebenzisa
isetshenziswa njengendawo emaphakathi ezidakamizweni nakudayi. Isetshenziselwa imithi ukuze kuhlanganiswe i-phenacetin, njll.
ezokuphepha
Lo mkhiqizo unobuthi. Kokubili ukuhogela kanye nokudonsa kuyingozi empilweni. Gqoka izibuko zokuphepha, gqoka ama-ovaroli avimbela ubuthi, futhi ugqoke izifihla-buso ezihlanganisiwe zothuli zokuhlunga lapho uthintana nothuli.
Iphakethe lenziwe ngezigubhu zensimbi ezincane ezivulekile, amabhodlela engilazi eyisikulufu, amabhodlela engilazi eyisivalo sensimbi, amabhodlela epulasitiki noma imiphongolo yensimbi (amathini) ngaphandle kwamakhreyithi okhuni. Gcina endaweni epholile, engenisa umoya. Gcina kude nomlilo, umthombo wokushisa, vikela elangeni eliqondile, bese uvala isitsha. Ukulayishwa okulula nokwehliswa uma uphatha.
