I use TMAH as catalyst。。the synthesized product can be dissolved in acetone and THF。。I can not use HCl to do titration，because the product can't dissolved in HCl。。。 so how about nonaqueous titration 。。can you  give me some documents？

[floralew]

why why why  nobody give me tips

Not enough information. What exactly are you trying to measure? The concentration of TMAH in your solution?

HCl doesn't necessarily need to be dissolved in water. HCl is available as a 4M solution in dioxane as well.

yes。。the concentration of TMAH in my product。。。first  I should dissolve the product，Acetone and THF are available，then I can do titration，but I‘m not sure the titrant。。。

you can try in glacial acetic acid medium. use per-choleric acid if possible. acetic may be a weak acid in some mediums.
