Embodiment 1
[0051] Equip a 1000-liter jacketed pressure reactor with a mechanical stirrer and a nitrogen gas introduction device. The temperature of the reactor was controlled by injecting a stream of steam or cold water into the jacket.
[0052] The raw material used in this method is safflower oil (300kg), alkali (flaky sodium hydroxide: 110kg) and the mixture of ethanol (280kg) and water (20kg) used as solvent.
[0053] The conjugation reaction of safflower oil was carried out as follows: 300 kg of safflower oil was placed in a reactor. Dissolve 110kg of flaky sodium hydroxide in 300kg of solvent and add it to the reactor. Under the protection of nitrogen, stir the resulting mixture and heat it to 150°C. The reaction lasts for 3 hours. The mixture in the pressure reactor was cooled to 120°C and transferred to another reactor to remove ethanol.
[0054] 100kg of saturated sodium chloride aqueous solution was added to the resulting mixture and stirred for 15 minutes, and the layers wer...
Embodiment 2
[0057] Embodiment 2 (comparative example)
[0058] Repeat Example 1, but without the step of adding saturated sodium chloride solution.
[0059] result
[0060] The results are analyzed as follows:
[0061] Example
[0062] Compared with the method of the prior art, the method of the present invention greatly reduces the content of ethyl ester.
