I-4-Nitroaniline(CAS#100-01-6) yazisa
umgangatho
Iikristale ezifana nenaliti etyheli. Ukutsha. Ukuxinana okuzalanayo 1. 424. Indawo yokubilisa 332 °c. Indawo yokunyibilika 148~149 °C. Indawo edanyazayo yi-199 °C. Inyibilika kancinci emanzini abandayo, inyibilika emanzini abilayo, i-ethanol, i-ether, ibenzene kunye nezisombululo zeasidi.
Indlela
Indlela ye-ammonolysis p-nitrochlorobenzene kunye namanzi ammonia kwi-autoclave kwi-180 ~ 190 °C, 4.0 ~ 4. Ngaphantsi kwemeko ye-5MPa, ukusabela malunga ne-lOh, oko kukuthi, i-p-nitroaniline yenziwe, i-crystallized kwaye ihlukaniswe yi-kettle yokwahlula kwaye yomiswe yi-centrifuge ukufumana imveliso egqityiweyo.
Indlela ye-nitrification ye-hydrolysis i-N-acetanilide i-nitrified nge-asidi exutywe ukufumana i-p-nitro i-N_acetanilide, kwaye emva koko ishushu kwaye i-hydrolyzed ukufumana imveliso egqityiweyo.
sebenzisa
Le mveliso ikwabizwa ngokuba ngumkhenkce idayi yedayi enkulu ebomvu yombala weGG, enokusetyenziswa ukwenza ityuwa emnyama K, yomqhaphu kunye nelinen yokudaya nokuprinta; Nangona kunjalo, ubukhulu becala buphakathi kwedayi ze-azo, ezifana nombala oluhlaza othe ngqo obumnyama B, i-asidi ephakathi kwe-brown G, i-asidi emnyama 10B, i-ATT yoboya be-asidi, uboya obumnyama be-D kunye ne-grey ngqo D. Inokusetyenziswa kwakhona njengendawo ephakathi kwi-pesticides kunye amayeza ezilwanyana, kwaye angasetyenziselwa ukwenza i-p-phenylenediamine. Ukongeza, i-antioxidants kunye ne-preservatives zinokulungiswa.
ukhuseleko
Le mveliso inetyhefu kakhulu. Inokubangela ityhefu yegazi enamandla kune-aniline. Esi siphumo sinamandla ngakumbi ukuba i-solvents eziphilayo zikhona ngexesha elinye okanye emva kokusela utywala. Ityhefu eqatha iqala ngokuqaqanjelwa yintloko, ukugungxulwa kobuso, nokuphefumla nzima, maxa wambi kukhatshwa sisicaphucaphu nokugabha, kulandele ubuthathaka bezihlunu, i-cyanosis, ukubetha kwentliziyo ebuthathaka, nokuphefumla nzima. Uqhagamshelwano lwesikhumba lunokubangela i-eczema kunye ne-dermatitis. impuku ngomlomo LD501410mg/kg.
Ngexesha lokusebenza, indawo yokuvelisa kufuneka ifakwe umoya ococekileyo, izixhobo kufuneka zivaliwe, umntu ngamnye kufuneka anxibe izixhobo zokukhusela, kwaye kufuneka kuqhutywe iimvavanyo zomzimba rhoqo, kuquka igazi, inkqubo ye-nervous kunye nokuhlolwa komchamo. Izigulane ezinetyhefu ebukhali zihamba ngokukhawuleza zishiya indawo, zinike ingqalelo ekugcinweni kobushushu besigulane, kunye ne-intravenously toject methylene blue solution. Olona xinaniso luphezulu luvumelekileyo emoyeni yi-0. 1mg／m3.
Ipakishwe kwingxowa yeplastiki efakwe iplastiki, igubu le-fiberboard okanye idrum yentsimbi, kwaye umphanda ngamnye ungama-30kg, 35kg, 40kg, 45kg, kunye nama-50kg. Ukuthintela ukuvela elangeni nasemvuleni ngexesha lokugcina nokuthutha, kwaye uthintele ukutyumza nokuqhekeka. Gcina kwindawo eyomileyo nengena umoya. Igcinwa kwaye ihanjiswe ngokuhambelana nezibonelelo ze-organic compounds ezinetyhefu kakhulu.
