[0028] (1) Vent nitrogen to the reaction kettle to exhaust oxygen. When exhausting oxygen, increase the nitrogen flow to 0.7-1.3L / min. After oxygen exhausting for 10-15min, reduce the nitrogen flow to 0.2-0.3L / min, and add it under the protection of nitrogen. 25-36g of ethylene glycol polyoxyethylene ether (average molecular weight is 400), 624-706g of palm oil, stirring and heating to 62-70°C at a rotation speed of 100-200r / min, to obtain a heated mixture a;

[0029] (2) Add 53-62g of zinc oxide to the mixture a prepared in step (1), and stir for 12-15min at a rotating speed of 200-300r / min to prepare mixture b;

[0030] (3) Heat the mixture b prepared in step (2) to 108-120°C, add 26-30g of water and 7.8-11.5g of succinic anhydride, keep the temperature at 108-120°C, increase the speed to 500- Stirring reaction at 700r / min for 80-100min to prepare the reactant; ...

[0040] A method for preparing palm oil fatty acid zinc, comprising the following steps:

[0041] (1) Vent nitrogen to the reaction kettle to exhaust oxygen. When exhausting oxygen, increase the nitrogen flow to 0.8L / min. After 14 minutes of oxygen exhaust, reduce the nitrogen flow to 0.2L / min, and add 26g of ethylene glycol polyoxygen under nitrogen protection. Vinyl ether (average molecular weight is 400), 628g palm oil, stirred and heated to 64°C at a rotation speed of 100r / min to obtain heated mixture a;

[0042] (2) Add 54g of zinc oxide to the mixture a prepared in step (1), and stir for 15min at a rotating speed of 200r / min to prepare mixture b;

[0043] (3) Heat the mixture b prepared in step (2) to 110°C, add 26g of water and 8g of succinic anhydride, keep the temperature at 110°C, increase the speed to 500r / min and stir the reaction for 100min to obtain the reaction thing;

Abstract

The invention discloses a preparation method of palm oil fatty acid zinc, which comprises the following steps: (1) introducing nitrogen into a reaction kettle to discharge oxygen, increasing the nitrogen 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 while stirring to obtain a heated mixture a; (2) adding zinc oxide 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 butanedioic 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 succinic acid and ethylene glycol polyoxyethylene ether, and then introducing water for cooling while stirring to prepare palm oil fatty acid zinc. The zinc content of the palm oil fatty acid zinc prepared by the process disclosed by the invention is as high as 13.96% or above, and the requirement of applying the palm oil fatty acid zinc to a feed additive can be met.

Description

technical field [0001] The invention belongs to the technical field of fatty acid zinc preparation, and in particular relates to a preparation method and application of palm oil fatty acid zinc. Background technique [0002] The English name of zinc fatty acid (Zinc Fatty Acid) is abbreviated as ZNFA. The industrial product is usually light yellow powder or white granule. It has good anti-sulfur pollution and can be widely used in food, feed and other fields. [0003] Chinese patent application document "A new process for rapidly synthesizing fatty acid zinc (publication number: CN102976916A)" discloses a new process for rapidly synthesizing fatty acid zinc, which will react fatty acid, zinc oxide and hydrogen peroxide at a certain temperature to generate fatty acid zinc. The process of the invention is simple and environmentally friendly, and the fatty acid zinc product is of high quality, but the content of zinc prepared according to the method is small, which cannot meet...
