What is O-TOLUIDINE DISULFONIC ACID?
Chemical properties
O- toluidine disulfonic acid is crystallize from water in needles. One hundred grams of the aqueous solution at 18 ℃ contains 0.226 g of the anhydrous acid. The substance is insoluble in alcohol, ether, and glacial acetic acid. o-Tolidine-6,6' -disulfonic acid is produced from 2-nitrotoluene-4-sulfonic acid by reduction with zinc and sodium hydroxide solution and subsequent rearrangement. o-Tolidine-6,6' -disulfonic acid is used to make yellow dyes for wool.
