Txoj kev khaws cia

Khaws nyob rau hauv ib lub warehouse txias thiab ventilated.Khaws kom deb ntawm qhov hluav taws kub thiab qhov cua sov.Lub pob yog kaw.Nws yuav tsum tau muab cais los ntawm oxidants, acids thiab edible tshuaj, thiab tsis txhob sib tov cia.Cov khoom siv tua hluav taws ntawm cov khoom sib txuam thiab ntau npaum li cas yuav tsum tau muab.Qhov chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj cov xau.

Txoj kev synthesis

O-nitrochlorobenzene, kua alkali, hydrochloric acid thiab hydrochloric acid tau siv los ua raw khoom.Cov khoom nruab nrab o-nitrophenol tau txais los ntawm distillation, thiab tom qab ntawd o-nitrophenol yog hydrogenated nrog hydrogen los tsim o-aminophenol nyob rau hauv qee qhov kub thiab siab siv palladium carbon li catalyst thiab ethanol ua hnyav;
