| titleOfInvention | A kind of method for improving canthaxanthin preparation yield |
| abstract | The invention discloses a method for improving the preparation yield of canthaxanthin. In the one-step oxidation method to synthesize canthaxanthin, the control of the conditions and the yield of the product have a crucial impact on the implementation of the entire process. The invention adopts a one-step oxidation method to synthesize, and focuses on solving the problem of low product yield caused by the instability of canthaxanthin in the process of oxidant residue and post-treatment translocation under the condition of long-term heating; The transposition process is optimized, and oxidation inhibitors are added during the transposition process to avoid the damage to the product caused by the residual oxidant at high temperature. At the same time, the transposition temperature can be reduced and the transposition time can be shortened to solve the existing canthaxanthin yield. low issue. |
