4-Nitroaniline (CAS # 100-01-6)
zoo
Yellow koob zoo li siv lead ua. Hluav taws kub. Relative ntom ntom 1. 424. Boiling point 332 °c. Melting point 148 ~ 149 ° C. Flash point 199 ° C. Me ntsis soluble nyob rau hauv dej txias, soluble nyob rau hauv boiling dej, ethanol, ether, benzene thiab acid daws.
Txoj kev
Txoj kev ammonolysis p-nitrochlorobenzene thiab ammonia dej hauv autoclave ntawm 180 ~ 190 ° C, 4.0 ~ 4. Nyob rau hauv cov xwm txheej ntawm 5MPa, cov tshuaj tiv thaiv yog hais txog lOh, uas yog, p-nitroaniline yog generated, uas yog crystallized thiab sib cais los ntawm segregation kettle thiab qhuav los ntawm centrifuge kom tau cov khoom tiav.
Nitrification hydrolysis txoj kev N-acetanilide yog nitrified los ntawm tov kua qaub kom tau p-nitro N_acetanilide, thiab ces rhuab thiab hydrolyzed kom tau cov khoom tiav.
siv
Cov khoom no tseem hu ua ice dyeing dye loj liab GG xim puag, uas yuav siv tau los ua dub ntsev K, rau paj rwb thiab linen ntaub dyeing thiab luam ntawv; Txawm li cas los xij, nws yog qhov nruab nrab ntawm azo dyes, xws li ncaj qha tsaus ntsuab B, kua qaub nruab nrab xim av G, kua qaub dub 10B, kua qaub wool ATT, pluab dub D thiab ncaj grey D. Nws kuj tseem siv tau los ua ib qho nruab nrab rau cov tshuaj tua kab thiab veterinary tshuaj, thiab tuaj yeem siv los tsim p-phenylenediamine. Tsis tas li ntawd, cov tshuaj tua kab mob antioxidant thiab cov tshuaj tua kab mob tuaj yeem npaj tau.
kev ruaj ntseg
Cov khoom no muaj tshuaj lom heev. Nws tuaj yeem ua rau ntshav lom uas muaj zog dua li aniline. Cov nyhuv no tseem muaj zog dua yog tias cov kuab tshuaj organic muaj nyob rau tib lub sijhawm lossis tom qab haus cawv. Mob hnyav pib nrog mob taub hau, lub ntsej muag dej, thiab ua tsis taus pa, qee zaum nrog xeev siab thiab ntuav, ua raws li cov leeg tsis muaj zog, cyanosis, tsis muaj zog pulse, thiab ua tsis taus pa. Kev sib cuag ntawm daim tawv nqaij tuaj yeem ua rau eczema thiab dermatitis. nas qhov ncauj LD501410mg/kg.
Thaum lub sijhawm ua haujlwm, qhov chaw tsim khoom yuav tsum muaj qhov cua zoo, cov khoom siv yuav tsum raug kaw, tus neeg yuav tsum hnav cov khoom tiv thaiv, thiab yuav tsum tau kuaj xyuas lub cev tsis tu ncua, suav nrog ntshav, paj hlwb thiab kuaj zis. Cov neeg mob uas muaj tshuaj lom raug mob tam sim ntawd tawm ntawm qhov chaw, ua tib zoo saib xyuas tus neeg mob kom txuag tau qhov kub thiab txias, thiab txhaj tshuaj methylene xiav tshuaj intravenously. Qhov siab tshaj plaws tso cai rau huab cua yog 0. 1mg / m3.
Nws yog ntim rau hauv ib lub hnab yas lined nrog ib lub hnab yas, ib lub nruas fiberboard lossis lub nruas hlau, thiab txhua lub thoob yog 30kg, 35kg, 40kg, 45kg, thiab 50kg. Tiv thaiv kom tsis txhob raug tshav ntuj thiab nag thaum lub sijhawm khaws cia thiab kev thauj mus los, thiab tiv thaiv kev sib tsoo thiab tawg. Khaws rau hauv qhov chaw qhuav, ventilated. Nws yog khaws cia thiab thauj khoom raws li cov kev cai ntawm cov organic tebchaw uas muaj tshuaj lom heev.
