| properties | O-aminophenyl ether is a colorless oily flammable liquid. O-aminophenyl ether gradually turned red to brown on exposure to air and sunlight. O-aminophenyl ether insoluble in water, soluble in ether, ethanol, benzene and chloroform, etc., a weak alkaline, also soluble in inorganic acid solution. |
| Application | O-aminophenyl ether is used in pharmacy, making dyes, can be used in feed and food, can prevent fat, protein in the storage process of Oxidative deterioration, but also for the preservation of vitamin A and vitamin E and other drugs. In medicine, for the production of antipyretic analgesic phenacetin, tuberculosis and Disinfection preservative rivanol; Also for the preparation of phenol AS-VL, alizarin Red 5G and fast acid Blue R and other dyes. |
| Use | mainly used as dye intermediate, O-ethoxyaniline and 2-hydroxy-3-naphthoic acid in chlorobenzene solvent, using phosphorus trichloride as a catalyst, the condensation of phenol AS-PH. The chromophenol AS-PH is used for dyeing and printing cotton fiber and hemp fiber, and consumes about 500kg of O-ethoxyaniline per ton of this dye. used as intermediates of dyes, fragrances and medicines |
| production method | O-nitrophenyl ether ([610-67-3]) is produced by the reaction of nitrochlorobenzene with ethanol and caustic soda, O-ethoxyaniline was obtained by reduction. |
