is there any replacement compound instead of acetic/formic/citric/oxalic/.. acides used in dyehomes?

Here are lists of acids.  Most are not practical because they are too weak, too strong, react with the textile, or the biggest reason, they cost too much.  \n\nGive us the criteria for your needed acid and why the acids currently used will not work in your situation.  Your question is not clear.\n\nhttp://www.zirchrom.com/organic.htm\n\nhttp://www.cem.msu.edu/~reusch/VirtualText/acidity2.htm

C3H7NO2 \n\nwww.chemfinder.com is a useful resource.  \n\nI hope this helps :)

There is only one I can think of. 1-hexyne can be deprotonated with sodium in liquid ammonia, to yield a very basic, nucleophilic anion.\n\n2-hexyne has no such proton to remove.\n\n===\nThe poster below is also correct. NMR would be the fastest way. You wouldn't even have to use a deuterated solvent. (because the hexyne would be a liquid).

Was the dye the same brand as before. It may have been contaminated.

No, but I can think of some decent ones.  The most common immiscible household items are oil and water.\n\nDyes or food coloring will preferentially stain oil or water, but usually not both.  You could find one that preferred water over oil, and use the water to "extract" the dye from the oil.  Immiscibility is an important quality that is used in many extractions (see the link below).

It could simply mean using dyes that are not in the azo class of dyes.  That would include phthalocyanines and formazans for examnple.

Look up the site chemfinder.com.  its a good website if you have not heard of it already.

Lucas Reagent replaces the OH group by a Cl group.\nTherefore CH3-C5H8-OH + HCl -> CH3-C5H8-Cl + H2O
