Embodiment 1
[0022] Such as figure 1 Shown a kind of production method of ferrous malate, comprises the steps:
[0023] (1) Prepare the mother liquor: first mix sodium carbonate and deionized water at a ratio of 1:4 in the main reactor to prepare a sodium carbonate aqueous solution, and then heat the sodium carbonate aqueous solution to 30°C at a uniform rate within 5 minutes by irradiating. Then add malic acid to the sodium carbonate aqueous solution until the pH value of the solution in the main reactor reaches 5.0, then let the solution in the reactor stand and naturally cool to normal temperature to obtain the finished mother liquor and set aside;
[0024] (2) To configure the reaction solution, first pass inert gas into the auxiliary reactor to keep the pressure in the reactor constant at 0.9 times the standard atmospheric pressure, and the oxygen content in the reactor is lower than 2%, then solid ferrous lactate and deionized Water was added to the auxiliary reactor at a ratio of 1...
Embodiment 2
[0034] Such as figure 1 Shown a kind of production method of ferrous malate, comprises the steps:
[0035] (1) Prepare the mother liquor: first mix sodium carbonate and deionized water at a ratio of 1:8 in the main reactor to prepare a sodium carbonate aqueous solution, and then heat the sodium carbonate aqueous solution to 45°C at a uniform rate within 10 minutes by irradiating it. Then add malic acid to the sodium carbonate aqueous solution until the pH value of the solution in the main reactor reaches 6.5, then let the solution in the reactor stand and naturally cool to normal temperature to obtain the finished mother liquor and set aside;
[0036] (2) To configure the reaction solution, first pass inert gas into the auxiliary reactor to keep the pressure in the reactor constant at 1.3 times the standard atmospheric pressure, and the oxygen content in the reactor is lower than 2%, then solid ferrous lactate and deionized Water was added to the auxiliary reactor at a ratio ...
Embodiment 3
[0046] Such as figure 1 Shown, a kind of production method of ferrous malate comprises the steps:
[0047] (1) Prepare the mother liquor: first mix sodium carbonate and deionized water at a ratio of 1:6.5 in the main reactor to prepare a sodium carbonate aqueous solution, and then heat the sodium carbonate aqueous solution to 35°C at a uniform rate within 6.5 minutes by irradiating. Then add malic acid to the sodium carbonate aqueous solution until the pH value of the solution in the main reactor reaches 6, then let the solution in the reactor stand and naturally cool to normal temperature to obtain the finished mother liquor and set aside;
[0048] (2) To configure the reaction solution, first pass inert gas into the auxiliary reactor to keep the pressure in the reactor constant at 1 times the standard atmospheric pressure, and the oxygen content in the reactor is lower than 2%, and then the solid ferrous lactate and deionized Water was added to the auxiliary reactor at a ra...
