Tobias acid

Broken Gears - 20-10-2006 at 09:38

Anyone have an idea on how to synthesis this compound? I dont know where to look, I have tried google, but didnt really get anything I found useful.

From www.chemicalland21.com:
"Tobias acid ( 2-Amino-1-naphthalene Sulfonic acid), an important dye intermediate, is produced from naphthalene by a combination of the unit processes of sulfonation, nitration, reduction, and hydrolysis".

Could you perhaps give me a hint on where to look next time insteed of google. Some chemical databases, maybe?

If it is used as a dye intermediate then even common sense could tell you that searching the patents should be the most obvious first choice.

You can find the synthesis for Tobias acid in "Fundamental Processes of Dye Chemistry" on page 200.
