Method for removing glycidyl esters by using ionic liquid

[0057] Example

[0058] All ionic liquids used in the examples were purchased from Shanghai Chengjie Chemical Co., Ltd., and the purity was 98%.

[0059] Refined palm oil and refined soybean oil purchase from Yahai Jiari.

[0075] Example 1:

[0076] The experimental raw oil used in this embodiment is one of the same.

[0077] Take 17 parts by experimental raw oil were added at room temperature, to which 0.5% weight of raw oil, 1.0%, 1.5%, 2.0%, 2.5%, 3.0%, 3.5%, 4.0%, 5.0%, 6.0%, 8.0% 10.0%, 12.0%, 14.0%, 16.0%, 18.0% or 20.0% of the amount of ionic liquid 1-butylsulfonic acid-3-methylimidazole sulfate, ie [BSO 3 HMIM] [HSO 4 ], With a high-speed shearing machine 10,000r · min -1 After cutting 3 min, after mixing is mixed, stirring at 60 ° C for 1 h at 60 ° C, then using a high-speed centrifuge at room temperature to 8,000R · min -1 Centrifugation was 5 min, the oil phase was separated from the ionic liquid phase, and the upper layer oil phase was taken to detect the content of glycidyl glyceryl.

[0080] Example 2:

[0081] The experimental raw oil used in this embodiment is one of the same.

[0082] 2 experimental raw oils were taken at room temperature to add 1% or 10% of the ionic liquid N-sulfonate hydrogen sulfate in the weight of the material oil, and [BSO 3 HPY] [HSO 4 ], With a high-speed shearing machine 10,000r · min -1 The shear was mixed 3 min, and then stirred at 300 rpm at 60 ° C for 1 h, then the high-speed centrifuge was used at room temperature to 8,000r · min. -1 Centrifugation was 5 min, the oil phase was separated from the ionic liquid phase, and the upper layer oil phase was taken to detect the content of glycidyl glyceryl.
