A skin and severe eye
irritant. Decomposes violently at about
200°. Mixture with sulfuric acid + sulfur
trioxide may explode above 150°C. When
heated to decomposition it emits toxic
fumes of SOx and NOx. See also NITRO
COMPOUNDS OF AROMATIC
HYDROCARBONS and SULFONATES. |
| Hazard Information | Back Directory | [Chemical Properties]
Crystals. Soluble in water and
alcohol. | [Production Methods]
3-Nitrobenzenesulfonic acid is produced by dissolving nitrobenzene in 98 % sulfuric acid and heating to 80 ℃. Then 65 % oleum is added at this temperature, and the reaction is completed by heating for 9 h at 105 ℃ (higher temperatures are unsafe). After quenching the sulfonation mass in water, neutralizing with lime, and filtering off gypsum, the calcium salt of the product is converted to the sodium salt with sodium carbonate. After calcium carbonate has been removed by filtration, the sodium salt solution can be used directly or evaporated. |
