I-4-Nitrophenetole(CAS#100-29-8)

I-4-Nitrophenetole(CAS#100-29-8)

umgangatho
Iikristale ezimthubi. Indawo yokunyibilika yi-60 °C (58 °C), indawo yokubila yi-283 °C, 112 ~ 115 °C (0.4kPa), kunye noxinzelelo oluhambelanayo ngu-1. 1176. Inyibilika kancinane emanzini, i-ethanol ebandayo kunye ne-petroleum ebandayo. ether. Inyibilika kwi-ether, inyibilika kwi-ethanol eshushu kunye ne-ether yepetroleum eshushu.

Indlela
Ilungiswa yi-etherification reaction ye-p-nitrochlorobenzene kunye ne-ethanol. I-P-nitrochlorobenzene kunye ne-ethanol yongezwa kwi-kettle yokusabela, ubushushu buphakanyiswe ukuya kwi-82 °C, kunye nesisombululo se-ethanol ye-sodium hydroxide yongezwa, kwaye impendulo yenziwa kwi-85 ~ 88 °C nge-3h. I-alkalinity yesisombululo sokusabela yancitshiswa yaba ngaphantsi kwe-0.9%, ipholile ukuya kwi-75 °C, kwaye ixabiso le-pH lahlengahlengiswa kwi-6.7 ~ 7 kunye ne-hydrochloric acid egxininisiweyo. Emva kokuma kunye ne-stratification, i-oyile ye-oyile ithathwa kwaye i-nitrophenol ye-sodium ihlanjululwa ngokufudumeza kwamanzi, kwaye i-oyile ye-oyile ihlanjululwe phantsi koxinzelelo oluncitshisiweyo, kwaye isahlulo se-214 ~ 218 ° C (2. 66 ~ 5.32kPa) sithathwa. njengale mveliso.

sebenzisa
isetyenziswa njengendawo ephakathi kwiziyobisi kunye nedayi. Isetyenziselwa amayeza ukwenza i-phenacetin, njl.

ukhuseleko
Le mveliso inetyhefu. Zombini ukuphefumla kunye nokungeniswa kuyingozi kwimpilo. Nxiba iiglasi zokhuseleko, nxiba iiovaroli zokungena ezichasene netyhefu, kwaye unxibe iimaski zothuli ezizikhuphayo xa udibana nothuli.
Ipakethe yenziwe ngamagubu entsimbi amancinci avulekileyo, iibhotile zeglasi ezijijwayo, iibhotile zeglasi zentsimbi, iibhotile zeplastiki okanye imigqomo yentsimbi (iitoti) ngaphandle kwamakhreyithi enziwe ngamaplanga. Gcina kwindawo epholileyo nengena umoya. Gcina kude nomlilo, umthombo wobushushu, khusela ekukhanyeni kwelanga, kwaye uvale isikhongozeli. Ukulayisha okulula kunye nokukhulula xa uphatha.
