| Abstract | ||
| Chemical reduction of orthonitrophenol by using Tin-Hydrochloric acid system yielding a mixture of Tin salts and orthoaminophenol as an organometalic complexes. Separation process of orthoaminophenol in a pure and free form is the more difficult step while using precipitating process at suitable pH permits us to separate orthoaminophenol in a pure form with good yield and also reducing material losses without any needs to use solvent extraction with high cost organic solvents like diethylether and such. | ||
