Nzira
Ammonolysis nzira p-nitrochlorobenzene uye ammonia mvura mune autoclave pa 180 ~ 190 °C, 4.0 ~ 4. Pasi pemamiriro e5MPa, mhinduro yacho ndeye lOh, kureva kuti, p-nitroaniline inogadzirwa, iyo yakasvibiswa uye inoparadzaniswa nekettle yekuparadzanisa uye yakaomeswa ne centrifuge kuti iwane chigadzirwa chakapedzwa.
Nitrification hydrolysis nzira N-acetanilide inoiswa nitrified neasidhi yakasanganiswa kuti iwane p-nitro N_acetanilide, uye yozodziiswa uye nehydrolyzed kuti iwane chigadzirwa chapera.
use
Ichi chigadzirwa chinonziwo ice dyeing dhayi hombe dzvuku GG color base, iyo inogona kushandiswa kugadzira dema munyu K, yekotoni nemucheka werineni dhayi uye kudhinda; Nekudaro, inonyanya kuve yepakati yeazo dhayi, senge yakananga girini B, acid yepakati brown G, asidhi dema 10B, acid mvere ATT, fur black D uye yakananga grey D. Inogona zvakare kushandiswa sepakati pemishonga yekuuraya zvipembenene uye. mishonga yemhuka, uye inogona kushandiswa kugadzira p-phenylenediamine. Mukuwedzera, antioxidants uye kuchengetedza zvinogona kugadzirirwa.
kuchengeteka
Ichi chigadzirwa chine muchetura zvakanyanya. Inogona kukonzera chepfu yeropa iyo yakasimba kudarika aniline. Izvi zvinonyanya kusimba kana organic solvents iripo panguva imwe chete kana mushure mekunwa doro. Muchetura wakanyanya kunotanga nemusoro, kuputika kwechiso, uye kutadza kufema, dzimwe nguva kunoperekedzwa nekusvotwa uye kurutsa, zvichiteverwa nekushaya simba kwetsandanyama, cyanosis, kupera simba kwekufema, uye kutadza kufema. Kubata ganda kunogona kukonzera eczema uye dermatitis. gonzo remuromo LD501410mg/kg.
Panguva yekushanda, nzvimbo yekugadzira inofanirwa kunge ichifefeterwa zvakanaka, midziyo inofanirwa kuvharwa, munhu anofanirwa kupfeka zvekudzivirira, uye kuongororwa kwemuviri nguva dzose kunofanirwa kuitwa, kusanganisira ropa, tsinga uye kuongororwa weti. Varwere vane chepfu yakakomba vanobva vangobva panzvimbo, vanoteerera kuchengetedza kupisa kwemurwere, uye intravenously jekiseni methylene blue solution. Iyo yakanyanya kubvumidzwa kutenderera mumhepo i0. 1mg／m3.
Inotakurwa mubhegi repurasitiki rakaiswa bhegi repurasitiki, dhiramu refiberboard kana dhiramu resimbi, uye dhiramu rimwe nerimwe i30kg, 35kg, 40kg, 45kg, uye 50kg. Dzivirira kuratidzwa kuzuva nemvura panguva yekuchengetedza uye yekufambisa, uye kudzivirira kupwanyika nekupwanyika. Chengetedza munzvimbo yakaoma, ine mhepo. Inochengetwa uye kutakurwa zvinoenderana nezvinopihwa zvehupfu hwakanyanya organic komisheni.
