The work done in this thesis was undertaken to determine the extent of the isomers which were formed when 2,5-dichlorobenzenesulfonic acid was nitrated. Nitrations were carried out with various nitrating agents.

The pare toluidine salts of 2,5-dichloro-3-nitro-benzenesulfonic acid and 2-p-chlorobenzoate-3-nitro-5-chlorobenzenesulfonic acid were prepared.

Recrystallizations of the mixtures of the nitration products of 2,5-dichlorobenzenesulfonic acid were carried out in an attempt to purify the 3-nitro isomer.

Bromination of the phenol of the 3-nitro isomer was carried out in an attempt to separate the other isomers formed.
