| titleOfInvention | A kind of method by borneol synthesis of oxalic acid two borneol acetate |
| abstract | The invention discloses a kind of method from borneol synthesis of oxalic acid two borneol acetate, borneol is comprised the steps: to be dissolved in a certain amount of organic solvent, certain hour is reacted at a certain temperature with anhydrous oxalic acid under boric anhydride, pyroboric acid or metaboric acid or the catalyst action such as titanium sulfate, metatitanic acid, Filtration of catalyst not with reaction anhydrous oxalic acid, washed several times with water, supernatant liquid obtains thick product through distillation removing organic solvent, then obtains oxalic acid two borneol acetate through the unreacted raw material borneol of the removing such as steam distillation, recrystallization.Raw material borneol comprises d-Bomeol, L-Borneol, Bigpian.This reacts the organic solvents such as available aromatic hydrocarbon, branched paraffin as reaction medium.The present invention adopts conventional heating, mild condition, easy and simple to handle, and stock Product is easily separated, and side reaction is few, and product yield is high. |
