Chitetezo ndi chitetezo cha zolembera
(1) Makina oyang'anira zomangamanga ndi mpweya wabwino.
(2) Kupewa moto ndi njira zopewera kuphulika: kukhudzana ndi zakumwa zoyaka ndikuletsedwa. Kuzimitsa moto ndi njira zokuzimitsira moto: gwiritsani ntchito kutsitsi madzi, carbon dioxide, ufa wouma, chida choyimitsira chithovu choyenera.
(3) Chenjezo posungira ndi mayendedwe: Sungani m'chipinda chozizira bwino. Sungani mosiyana ndi oxidizer.
(4) Njira zodzitetezera: Mpweya wabwino, utsi wakomweko. Chitetezo cha khungu: Valani magolovesi oteteza komanso zovala zoteteza. Kuteteza maso: Valani magalasi oteteza chitetezo. Kukudzilitsani: Osadya, kumwa kapena kusuta mukamagwira ntchito. Njira yopangira mafakitale imapangidwa ndi condensation ya N, N-dimethylaniline ndi formaldehyde, distillation, crystallization ndi kuyeretsedwa, sulfure, ammonization ya urea ndi ammonium chloride ku 150-160 ℃, kusefera ndi kuyanika kwa mankhwala omalizidwa. Zakudya zopangira (kg, t) N, N-dimethylaniline (98%) 110 formaldehyde (37%) 460 urea 700 sulfure (99%) 350 ammonium chloride 630 p-aminobenzenesulfonic acid (100%)
