| titleOfInvention | The method that Technique of Nano Pd electro-catalysis chenodeoxycholic acid synthesizes ursodesoxycholic acid |
| abstract | The invention discloses a kind of methods of Technique of Nano Pd electro-catalysis chenodeoxycholic acid synthesis ursodesoxycholic acid, using proof gold as reaction electrode, using Technique of Nano Pd as catalyst, the solution of the 5 β cholanic acids containing 3 α, 7 ketone groups is first made by electrocatalytic reaction in sodium hydroxide solution with chenodeoxycholic acid；Electro-catalysis uses 3~9V DC power supplies, and hydrogen peroxide solution is slowly added to during electro-catalysis；Then pH value is adjusted to 10~10.5 with sodium hydroxide solution, continues electro-catalysis, this is slowly added to sodium borohydride solution in the process, and 2~4h of reaction is powered off up to the solution containing ursodesoxycholic acid, and crystal refining obtains fine work ursodesoxycholic acid.Reaction condition of the present invention is mild；Using relatively stable oxidant reduction agent, easily operated control；Catalyst and electrode can recycle, and cost input is low, and profit return is high；Section the time required to prepared by the present invention only needs final step to carry out crystal refining, efficient. |
