4-Nitroaniline(CAS#100-01-6) yambitsani
khalidwe
Makhiristo achikasu ngati singano. Zoyaka. Kachulukidwe wachibale 1. 424. Malo otentha 332 °c. Malo osungunuka 148 ~ 149 °C. Kuwala kwa 199 ° C. Kusungunuka pang'ono m'madzi ozizira, kusungunuka m'madzi otentha, ethanol, ether, benzene ndi asidi.
Njira
Ammonolysis njira p-nitrochlorobenzene ndi ammonia madzi mu autoclave pa 180~190 °C, 4.0~4. Pansi pa chikhalidwe cha 5MPa, zomwe zimachitika ndi lOh, ndiye kuti, p-nitroaniline imapangidwa, yomwe imapangidwa ndi crystallized ndikulekanitsidwa ndi ketulo ya tsankho ndikuumitsa ndi centrifuge kuti ipeze mankhwala omalizidwa.
Nitrification hydrolysis njira N-acetanilide ndi nitrified ndi asidi wosakaniza kupeza p-nitro N_acetanilide, ndiyeno kutentha ndi hydrolyzed kupeza yomalizidwa mankhwala.
ntchito
Chogulitsachi chimadziwikanso kuti utoto wopaka ayezi wopaka utoto waukulu wamtundu wa GG, womwe ungagwiritsidwe ntchito kupanga mchere wakuda K, utoto wa thonje ndi bafuta ndi kusindikiza; Komabe, ndi mtundu wapakatikati wa utoto wa azo, monga wobiriwira wakuda kwambiri B, asidi wapakati wa bulauni G, asidi wakuda 10B, ubweya wa asidi ATT, ubweya wakuda D ndi imvi yolunjika D. Itha kugwiritsidwanso ntchito ngati njira yapakatikati ya mankhwala ophera tizilombo komanso mankhwala a Chowona Zanyama, ndipo angagwiritsidwe ntchito kupanga p-phenylenediamine. Kuphatikiza apo, ma antioxidants ndi zoteteza zimatha kukonzedwa.
chitetezo
Mankhwalawa ndi oopsa kwambiri. Zingayambitse poizoni wamagazi omwe ali amphamvu kuposa aniline. Izi zimakhala zamphamvu kwambiri ngati zosungunulira za organic zilipo nthawi imodzi kapena mutamwa mowa. Pachimake poyizoni amayamba ndi mutu, kupukuta kumaso, ndi kupuma movutikira, nthawi zina limodzi ndi nseru ndi kusanza, kenako kufooka kwa minofu, cyanosis, kugunda kwamtima, ndi kupuma movutikira. Kukhudzana ndi khungu kungayambitse chikanga ndi dermatitis. makoswe oral LD501410mg/kg.
Pogwira ntchito, malo opangirako ayenera kukhala ndi mpweya wokwanira, zida ziyenera kutsekedwa, munthu ayenera kuvala zida zodzitetezera, komanso kuyezetsa thupi pafupipafupi kuyenera kuchitidwa, kuphatikiza kuyesa magazi, dongosolo lamanjenje ndi mkodzo. Odwala omwe ali ndi poyizoni wapoizoni nthawi yomweyo amachoka pamalopo, tcherani khutu ku kuteteza kutentha kwa wodwalayo, ndikubaya jekeseni wa methylene blue solution. Kuchuluka kololedwa mumlengalenga ndi 0. 1mg／m3.
Imayikidwa mu thumba la pulasitiki lokhala ndi thumba la pulasitiki, ng'oma ya fiberboard kapena ng'oma yachitsulo, ndipo mbiya iliyonse ndi 30kg, 35kg, 40kg, 45kg, ndi 50kg. Pewani kukhudzana ndi dzuwa ndi mvula panthawi yosungira ndi kuyendetsa, komanso kupewa kuphwanyidwa ndi kusweka. Sungani pamalo owuma, opanda mpweya wabwino. Amasungidwa ndikusamutsidwa molingana ndi zomwe zimaperekedwa ndi mankhwala oopsa kwambiri.
