hydroxyvanilline | |||||||
5 grams bromovanilline were refluxed with 25 mg Cu and 9 grams Naoh to obtain hydroxyvanilline. after 8 hours the mixture was acidified with Hcl until Ph 2. non polar solvent was added (ether). Mixture was just a little bit shaked. 3layers forms:Up layer is yellow transparent(Ether and hydroxyvanilline?) Middle layer is orange (aqueus no organic). On bottom layer there is a mass of precipitate (unreacted bromovanilline?). Please help. |
