Additional information
Physical-Chemical testing was conducted by Slovnaft Vurup, a.s., Department of Testing Laboratories, in July and August 2010.
There are 5 aromatic sulphonic acids that were tested for physical-chemical properties in 2010. The appearance of those samples at 20C was:
Benzene sulphonic acid (CAS No. 98-11-3) - aqueous solution (ca 65%) as tested. Hygroscopic when dried.
Hydroxybenzene sulphonic acid (CAS No. 1333-39-7) - aqueous solution (ca 65%) as tested. Hygroscopic when dried.
Cumene sulphonic acid (CAS No. 37953-05-2) - aqueous solution (ca 65%) as tested. Hygroscopic when dried.
Xylene sulphonic acid (CAS No. 25321-41-9) - aqueous solution (ca 65%) as tested. Hygroscopic when dried.
Toluene sulphonic acid (CAS No. 104-15-4) - monohydrate crystal as tested. Hygroscopic when dried.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
