This post was last edited by sunjl1981 on 2015-8-15 at 11:09. In my process for producing 4-nitro-2-aminophenol using sodium hydrosulfide, the yield is roughly such that 600 kg of ***chlorobenzene is used to produce 400–430 kg of 4-nitro-2-aminophenol (on a percent basis). This process has been successfully used in large-scale production for many years
