Sulphonation products of naphthalene, processes for their preparation, and their use |
| abstract |
The invention concerns new sulfonation products of naphthalene, process for their preparation according to which naphthalene is sulfonated under special reaction conditions by sulfur trioxide in inert organic solvents. The new sulfonation products are used as intermediates e.g. for the production of naphthalene-1,5-disulfonic acid. |
