| titleOfInvention | A kind of preparation method and preparation device of safe calcium L-5-methyltetrahydrofolate |
| abstract | The invention relates to the technical field of preparation of L-5-methyl tetrahydrofolate calcium, and specifically discloses a preparation method and a preparation device of a safe L-5-methyl tetrahydrofolate calcium; comprising a rack assembly, a reaction kettle, A constant temperature jacket, a folic acid powder feeding device and a stirring assembly; the frame assembly is provided with a nitrogen compression tank, and the nitrogen compression tank is connected with a nitrogen pipe extending into the lower end of the inner cavity of the kettle body. The upper end is also provided with a hydrogen exhaust pipe extending into the upper end of the inner cavity of the kettle body, and the outer end of the hydrogen exhaust pipe is connected with a hydrogen explosion-proof device; the L-5-methyltetrahydrofolate calcium disclosed in the present invention adopts a reduction method to prepare tetrahydrogen When folic acid is used, the generated hydrogen can be intermittently discharged, and the discharged hydrogen can be ignited by a hydrogen explosion-proof device during discharge, which can effectively prevent the hydrogen generated in the process of preparing tetrahydrofolate by reduction method from explosion, which greatly improves the whole preparation. process security. |
