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

khalidwe
Makristalo otuwa achikasu. Malo osungunuka ndi 60 °C (58 °C), malo otentha ndi 283 °C, 112 ~ 115 °C (0.4kPa), ndipo kachulukidwe kakang'ono ndi 1. 1176. Amasungunuka pang'ono m'madzi, ethanol yozizira ndi mafuta ozizira. ether. Kusungunuka mu etha, kusungunuka mu ethanol yotentha ndi mafuta otentha a petroleum ether.

Njira
Imakonzedwa ndi etherification reaction ya p-nitrochlorobenzene ndi ethanol. P-nitrochlorobenzene ndi Mowa zinawonjezeredwa ku ketulo anachita, kutentha kunakwezedwa 82 °C, ndi Mowa sodium hydroxide njira anawonjezedwa dropwise, ndi zimene zinachitika pa 85 ~ 88 °C kwa 3h. The alkalinity ya yankho yankho anachepetsedwa kukhala pansi 0,9%, utakhazikika kwa 75 °C, ndi pH mtengo kusintha 6.7 ~ 7 ndi anaikira hydrochloric acid. Pambuyo poyima ndi stratification, mafuta osanjikiza amatengedwa ndipo sodium nitrophenol imatsukidwa ndi kutentha kwa madzi, ndipo mafuta osanjikiza amasungunuka pansi pa kupanikizika kochepa, ndipo gawo la 214 ~ 218 ° C (2. 66 ~ 5.32kPa) limatengedwa. monga mankhwala.

ntchito
amagwiritsidwa ntchito ngati wapakatikati mu mankhwala ndi utoto. Amagwiritsidwa ntchito muzamankhwala kupanga phenacetin, etc.

chitetezo
Mankhwalawa ndi oopsa. Kukoka mpweya ndi kumeza zonse ndizovulaza thanzi. Valani magalasi oteteza chitetezo, valani maovololo oletsa kulowetsa poyizoni, ndi kuvala zophimba zodzitetezera ku fumbi mukakumana ndi fumbi.
Zopakazo zimapangidwa ndi ng'oma zing'onozing'ono zachitsulo zotseguka, mabotolo agalasi opukutira pakamwa, mabotolo agalasi okhala ndi chivindikiro, mabotolo apulasitiki kapena migolo yachitsulo (zitini) kunja kwa mabokosi amatabwa. Sungani m'nyumba yosungiramo zinthu zoziziritsa kukhosi komanso mpweya wabwino. Khalani kutali ndi moto, gwero la kutentha, tetezani ku dzuwa lolunjika, ndikusindikiza chidebecho. Kutsitsa pang'ono ndikutsitsa mukamagwira.
