A method for separating theobromine from a mixture with caffeine |
| abstract |
The solution relates to theobromine separationnfrom a mixture with caffeine basedntheir different solubilities innaqueous inorganic solutions ornorganic acids. Differences in solubilitynthe result of a different protonizationnsalts of theobromine and caffeine. Mixturentheobromine with caffeine is digested withnaqueous inorganic or organic solutionnan acid selected from the group consisting ofnincluding IN and 2N hydrochloric acid,n1M sulfuric acid, 3M acidnsulfuric or 50% (v / v) acidnacetic acid at elevated temperature and undissolvedntheobromine is aspirated after coolingnat 20 ° c. |
