반응 단계

Using the procedure described above and 5.0 g of a chromium-containing Raney cobalt catalyst containing about 20-30 weight percent aluminum, 1.5 to 2.5 weight percent nickel and the remainder cobalt, 2-benzamido 4-chloro 5-nitrophenol is hydrogenated for a total of 4 hours to obtain the corresponding amine, 5-amino 2-benzamido 4-chlorophenol. Analysis of a sample of the reaction mixture taken and analyzed in accordance with the procedure used in the preceding example, show that the purity of the product is 98.4 percent and the presence of 0.1 percent of dechlorinated by product. The azo, azoxy and hydroxylamine intermediate products are soluble in the final filtrate and thus are easily removed from the product. No starting material is detected.
