Selective nitration of aromatic and substituted aromatic compositions |
| abstract |
SELECTED NITRATION OF AROMATIC AND SUBSTITUTED AROMATIC COMPOSITIONS Abstract of the Disclosure This invention relates to an improvement in a process for nitrating an aromatic or substituted aromatic compound e.g., toluene or ortho-xylene, by reacting such aromatic or sub-stituted aromatic in the presence of nitric acid. The improve-ment for enhancing the rate of nitration as well as the select-ivity of nitration at the para-position in this process com-prises carrying out the nitration reaction in the presence of at least an effective amount of anhydrous calcium sulfate or soluble anhydrite. |
