4-Nitrophenetole (CAS # 100-29-8)
ubuziranenge
Ibara ry'umuhondo ryerurutse. Ahantu ho gushonga ni 60 ° C (58 ° C), aho batetse ni 283 ° C, 112 ~ 115 ° C (0.4kPa), naho ubucucike bugereranije ni 1. 1176。 Kubora buhoro buhoro mumazi, Ethanol ikonje na peteroli ikonje ether. Gukemura muri ether, gushonga muri Ethanol ishyushye na peteroli ishyushye.
Uburyo
Byateguwe na etherification reaction ya p-nitrochlorobenzene na Ethanol. P. Ubunyobwa bwibisubizo byaragabanutse kugera munsi ya 0.9%, bukonja kugera kuri 75 ° C, kandi agaciro ka pH kahinduwe kuri 6.7 ~ 7 hamwe na aside hydrochloric yibanze. Nyuma yo guhagarara no gutondekanya, hafatwa igipande cyamavuta hanyuma sodium nitrophenol ikogejwe namazi ashyushye, hanyuma igipande cyamavuta kigahinduka munsi yumuvuduko ukabije, hanyuma agace ka 214 ~ 218 ° C (2. 66 ~ 5.32kPa) karafatwa. nk'iki gicuruzwa.
Koresha
ikoreshwa nk'igihe gito mu biyobyabwenge n'amabara. Ikoreshwa mubuvuzi muguhuza phenacetine, nibindi.
umutekano
Ibicuruzwa bifite uburozi. Guhumeka no kuribwa byombi byangiza ubuzima. Wambare ibirahure byumutekano, wambare hejuru yuburozi bwinjira, kandi wambare kwiyungurura-kwiyungurura ivumbi ryuzuye ivumbi mugihe uhuye numukungugu.
Ibipfunyika bikozwe mu ngoma ntoya ifunguye ibyuma, amacupa yikirahure yiminwa, icupa ryicyuma kanda kumunwa wikirahure, amacupa ya pulasitike cyangwa ingunguru yicyuma (amabati) hanze yikarito yimbaho. Ubike mu bubiko bukonje, buhumeka. Irinde umuriro, isoko yubushyuhe, urinde urumuri rwizuba, kandi ushireho ikintu. Gupakira urumuri no gupakurura mugihe ukora.
