[0029] In an embodiment, the preparation method of described palm oil fatty acid magnesium comprises the following steps:

[0030] (1) Vent nitrogen to the reaction kettle to exhaust oxygen, increase the nitrogen flow rate to 0.9-1.2L / min when exhausting oxygen, after 10-14min of oxygen exhausting, reduce the nitrogen flow rate to 0.1-0.2L / min, add under the protection of nitrogen 30-45g of ethylene glycol polyoxyethylene ether with an average molecular weight of 1000 and 312-350g of palm oil are stirred and heated to 62-65°C at a rotation speed of 200-300r / min to obtain a heated mixture a;

[0031] (2) Add 19-22g of magnesium hydroxide to the mixture a prepared in step (1), and stir for 8-14min at a rotating speed of 300-500r / min to prepare mixture b;

[0032] (3) Heat the mixture b prepared in step (2) to 106-117°C, add 14-17g of water and 3.9-5.7g of maleic anhydride, keep the temperature at 106-117°C, and increase the speed to Stir and react at 600-800r / min for 74-90min t...

Embodiment 1

[0036] A kind of preparation method of palm oil fatty acid magnesium, comprises the following steps:

[0037] (1) Pass nitrogen to the reaction kettle to exhaust oxygen. When exhausting oxygen, increase the nitrogen flow rate to 0.9L / min. After 14 minutes of oxygen exhaustion, reduce the nitrogen flow rate to 0.2L / min. Ethylene glycol polyoxyethylene ether and 315g of palm oil were stirred and heated to 63°C at a rotation speed of 200r / min to obtain heated mixture a;

[0038] (2) Add 19.6g of magnesium hydroxide to the mixture a prepared in step (1), and stir for 14min at a rotating speed of 300r / min to obtain mixture b;

[0039] (3) Heat the mixture b prepared in step (2) to 108°C, add 15g of water and 4.2g of maleic anhydride, keep the temperature at 108°C, increase the speed to 600r / min and stir for 90min, produce reactants;

[0040] (4) The reactant prepared in step (3) is filtered, dehydrated, reclaimed maleic acid and ethylene glycol polyoxyethylene ether with an avera...

Embodiment 2

[0042] A kind of preparation method of palm oil fatty acid magnesium, comprises the following steps:

[0043] (1) Pass nitrogen to the reaction kettle to exhaust oxygen, increase the nitrogen flow to 1L / min during oxygen exhaust, after 12 minutes of oxygen exhaust, turn down the nitrogen flow to 0.1L / min, add 38g of ethyl alcohol with an average molecular weight of 1000 under nitrogen protection Glycol polyoxyethylene ether, 340g palm oil, stirred and heated to 64°C at a rotation speed of 300r / min, to obtain heated mixture a;

[0044] (2) Add 20.6g of magnesium hydroxide to the mixture a prepared in step (1), and stir for 8min at a rotating speed of 500r / min to prepare mixture b;

[0045] (3) Heat the mixture b prepared in step (2) to 115°C, add 15.8g of water and 5g of maleic anhydride, keep the temperature at 115°C, increase the rotation speed to 800r / min and stir for 75min, produce reactants;

[0046] (4) The reactant prepared in step (3) is filtered, dehydrated, reclaime...

Abstract

The invention discloses a preparation method of palm oil fatty acid magnesium, which comprises the following steps: (1) introducing nitrogen into a reaction kettle to discharge oxygen, increasing thenitrogen flow during oxygen discharge, reducing the nitrogen flow after oxygen discharge, adding ethylene glycol polyoxyethylene ether and palm oil under the protection of nitrogen, and heating whilestirring to obtain a heated mixture a; (2) adding magnesium hydroxide into the mixture a prepared in the step (1), and stirring to obtain a mixture b; (3) heating the mixture b prepared in the step (2), adding water and maleic anhydride, keeping the temperature unchanged, increasing the rotating speed, and carrying out a stirring reaction to prepare a reactant; and (4) filtering and dehydrating the reactant prepared in the step (3), recovering maleic acid and ethylene glycol polyoxyethylene ether, and then introducing water for cooling while stirring to prepare palm oil fatty acid magnesium. The method is high in palm oil fatty acid magnesium production efficiency, suitable for large-scale production, low in environmental pollution, low-carbon and environment-friendly, and can be vigorously popularized and applied to feed additives.

Description

technical field [0001] The invention belongs to the technical field of fatty acid magnesium preparation, and in particular relates to a preparation method and application of palm oil fatty acid magnesium. Background technique [0002] Magnesium fatty acid is a derivative product of fatty acid, which is widely used in food, feed and other fields. [0003] The fatty acid magnesium prepared by the prior art has excellent performance, but the magnesium content is small, which cannot meet the needs of popularization and application. [0004] For example, the method disclosed in the Chinese literature "Research and Application of Castor Oil Fatty Acid Magnesium Production Technology (published in the Journal of Inner Mongolia University for Nationalities, 2011, 26 (5): 552-554)" prepares fatty acid magnesium, and the magnesium content is relatively small, only 3.8%- 4.2%, unable to meet the application requirements in feed additives. Contents of the invention [0005] The pres...
