| 4-Nitrophenol Usage And Synthesis | |
| Chemical Properties | Yellow to tan crystals or powder |
| Uses | Used in the manufacturing of pharmaceuticals, fungicides, dyes. |
| Definition | ChEBI: A member of the class of 4-nitrophenols that is phenol in which the hydrogen that is para to the hydroxy group has been replaced by a nitro group. |
| Uses | manufacture of pharmaceuticals, fungicides, dyes. Indicator in 0.1% alcohol solution. pH: 5.6 colorless, 7.6 yellow. |
| General Description | A white to light yellow crystalline solid. Contact may severely irritate skin and eyes. Poisonous by ingestion and moderately toxic by skin contact. |
| Air & Water Reactions | Soluble in hot water and more dense than water. |
| Reactivity Profile | 4-Nitrophenol is a slightly yellow, crystalline material, moderately toxic. Mixtures with diethyl phosphite may explode when heated. Decomposes exothermally, emits toxic fumes of oxides of nitrogen [Lewis, 3rd ed., 1993, p. 941]. Decomposes violently at 279°C and will burn even in absence of air [USCG, 1999]. Solid mixtures of the nitrophenol and potassium hydroxide (1:1.5 mol) readily deflagrate [Bretherick, 5th Ed., 1995]. |
| Health Hazard | Inhalation or ingestion causes headache, drowsiness, nausea, and blue color in lips, ears, and fingernails (cyanosis). Contact with eyes or skin causes irritation; can be absorbed through skin to give same symptoms as for inhalation. |
| Purification Methods | Crystallise 4-nitrophenol from water (which may be acidified, e.g. with N H2SO4 or 0.5N HCl), EtOH, aqueous MeOH, CHCl3, *benzene or pet ether, then dry it in vacuo over P2O5 at 25o. It can be sublimed at 60o/10-4mm. The 4-nitrobenzoate had m 159o (from EtOH). [Beilstein 6 IV 1279.] |
