Kuchengetedza uye pennants yekuchengetedza vashandi
(1) Injiniya yekudzora ine system uye kufefetedza.
(2) Kudzivirirwa kwemoto uye matanho ekudzivirira ekuputika: kusangana nezvinwiwa zvinopisa zvinorambidzwa. Kurwisa moto uye kudzimisa moto nzira: shandisa mvura pfapfaidzo, carbon dioxide, poda yakaoma, yakakodzera furo moto wekudzimisa mumiriri.
(3) Chenjedzo yekuchengetedza uye kutakura: Chengetera mune inotonhorera, ine mhepo nzvimbo. Chengetedza zvakasiyana kubva kune oxidizer.
(4) Matanho ekudzivirira ega: Kufefetedza, kupera kwemuno. Kuchengetedzwa kweganda: Pfeka magirovhosi ekudzivirira uye zvipfeko zvekudzivirira. Kudzivirirwa kweziso: Pfeka magogorosi ekuchengetedza. Kuisa yekudzivirira: Usadya, kunwa kana kuputa paunenge uchishanda. Iyo indasitiri yekugadzira nzira inogadzirwa neiyo condensation yeN, N-dimethylaniline uye formaldehyde, distillation, crystallization uye kuchenesa, sarufa, ammonization ye urea uye ammonium chloride pa150-160 ℃, kusefa uye kuomesa kwechigadzirwa chakapedzwa. Mbishi yekushandisa (kg, t) N, N-dimethylaniline (98%) 110 formaldehyde (37%) 460 urea 700 sarufa (99%) 350 ammonium chloride 630 p-aminobenzenesulfonic acid (100%)
