4(5) HYDROXYMETHYL IMIDAZOLE PICRATE SYNTHESIS FROM FRUCTOSE
Dear Sir,
I m following same procedure of organic synthesis. But i got green colour filtrate after passing H2S gas. I dont understand where is mistake. Whether before adding Picric acid we have to neutralize HCl. Can this HCl interfere with formation of picrate. Kindly guide

Here's a reference to your process, and also a better procedure, see following the second procedure this improves your yield: https://archive.org/stream/OrganicSynthesesVolume24/OrganicSynthesesVolume24_djvu.txt

Yes, I m following same procedure of Org. Synth, 1944, 28,64. 1.I want to know whether H2S is passed from sol under hot conditions or at room temp. 2. After passing H2S gas from sol I got green color filtrate rather than light brown filltrate. 3. Before adding picric acd if there is need to neutralize added HCl for passing H2S gas. 4. if there is need to neutralize HCl then which base should be used.
