I tried making indole-acetic-acid methyl ester and I'm not sure it worked. I tried making an anahydrous 3% HCl in methanol solution but I had trouble measureing the amount of HCl in solution because as I was gassing alot of methanol evaporated. Because of this, I might have added too much acid. When I added IAA, the solution quickly turned purple. Does that sound right? I'm prety sure that means the IAA was destroyed, but I'm not sure. I heated the solution for a couple hours. I evaporated a sample and got a thick purple oil. What is this? Do you think it's the IAA ester or what?
