Embodiment 1
[0019] A kind of preparation method of rexohylic acid chromium, the steps are as follows:
[0020] (1) Salt-forming reaction steps: Add 100 moles of rexoctanoic acid, 65 moles of chromium oxide, 20 moles of amine compounds, and 1500 moles of water into a 100-liter reactor with a heating device, electric stirring, and a thermometer. Heating to 70-80°C for reaction, and reacting under the condition of stirring for 6 hours, so that carbon dioxide overflows, stop heating, the salt forming reaction is completed, and chromium rexohexanoate is obtained.
[0021] (2) Drying step: crystallize and centrifuge the chromium raisooctanoate obtained in step (1) to obtain granular chromium raisooctanoate, place the granular chromium raisooctoate in a stainless steel drying sieve with upper and lower air permeability, and dry in a drying oven. After 24 hours, sieve the dried chromium rexohylate granules to obtain a finished product, and the content of the chromium rexohexylate is measured to b...

[0027] A kind of preparation method of rexohylic acid chromium, the steps are as follows:
[0028] (1) Salt-forming reaction steps: Add 100 moles of rexoctanoic acid, 65 moles of chromium oxide, 40 moles of amine compounds, and 1500 moles of water into a 100-liter reactor with a heating device, electric stirring, and a thermometer. While stirring Heating to 70-80°C for reaction, and reacting under the condition of stirring for 6 hours, so that carbon dioxide overflows, stop heating, the salt forming reaction is completed, and chromium rexohexanoate is obtained.
[0029] (2) Drying step: crystallize and centrifuge the chromium raisooctanoate obtained in step (1) to obtain granular chromium raisooctanoate, place the granular chromium raisooctoate in a stainless steel drying sieve with upper and lower air permeability, and dry in a drying oven. After 24 hours, sieve the dried chromium rexohylate granules to obtain a finished product, and the content of the chromium rexohexylate i...
