3-Nitro-4-hydroxyphenylarsonic acid is a valuable feed additive. In this paper, 3-nitro-4-hydroxyphenylarsonic acid was prepared from 2-nitrophenol through protecting phenol by benzoate group and arsenite reaction, with total recovery of 54 %. Effect factors on the yield of product such as temperature and time were studied respectively.
