Embodiment 1

[0033] 19 parts of 31% ionic liquid [BPy]THR and 61 parts of 17% (NH 4 ) 3 C 6 h 5 o 7 Mix evenly to obtain a two-phase extraction system, then add 20 parts of IDA-PAM-Gel with a mass fraction of 46% to obtain a gel-like mixture, burn the above-mentioned gel-like mixture under nitrogen protection for two hours to form powdery particles, Then it was stored in a vacuum oven at 40° C. and left to stand for 48 hours to prepare the ionic liquid active adsorption material.

[0034] Take out this adsorption material, be used for capturing dioctyl sebacate in the plasticizer, adopt the adsorption material of the present invention to carry out the capture method of dioctyl sebacate in the plasticizer is that the mass ratio of plasticizer and adsorption material is 3:1, the adsorption temperature is 27°C, and the adsorption time is 30min.

[0035] Specific types of plasticizers are polyol ester plasticizers.

[0036] The permeability of the target before and after capture is recor...

Embodiment 2

[0038] The preparation method of this embodiment is the same as that of Example 1, the only difference being that the type of ionic liquid in the preparation process is different. In this embodiment, the ionic liquid is changed to ([TBA]Cl) (tetrabutylammonium chloride), and the remaining conditions The permeability of the target before and after capture is recorded in Table 1.

Embodiment 3

[0040] The preparation method of this example is the same as that of Example 1, the difference is only that the type of ionic liquid in the preparation process is different, and in this example, the ionic liquid is changed to [Emim][PF6](1-ethyl-3-methylimidazole hexafluorophosphate), and the rest of the conditions were unchanged, and the permeability of the target before and after capture was recorded in Table 1.

[0041]As can be seen from the above examples and Table 1, the composition of the ionic liquid in the adsorbent is changed, and the permeability for separating dioctyl sebacate in the plasticizer is 99.6%, 74.3%, and 59.3%, respectively, so using When [BPy]THR was used as an ionic liquid, the penetration rate of dioctyl sebacate in the plasticizer was the largest, and the penetration effect was the best.

[0042] Depend on figure 1 , 2 And 3, it can be seen that when the ionic liquid in the adsorption material is [BPy]THR, a coral-like structure can be formed, and...

Abstract

The invention discloses an adsorption material for dioctyl sebacate in a plasticizer, a preparation method and an application thereof. The method is characterized in that ionic liquid [BPy]THR, (NH4)3C6H5O7 and IDA-PAM-Gel are mixed and burned; the burning temperature is 150-170 DEG C; and the ionic liquid active adsorption material is prepared by the ionic liquid [BPy]THR: (NH4)3C6H5O7: IDA-PAM-Gel with a mass ratio of 1:6:3. The method is fast and convenient, and the special ionic liquid, salt and graft chelating gel are used in preparation, and the prepared ionic liquid active adsorption material has high targeting and collection efficiency. The adsorption rate of the dioctyl sebacate in the plasticizer is up to 99.5% by the method. The material has a wide linear range, low detection limit and relatively small standard deviation, which can meet the national requirements for the detection of dioctyl sebacate in plasticizers.

Description

technical field [0001] The invention relates to the fields of green separation and environmental protection, in particular to a dioctyl sebacate adsorption material in a plasticizer, a preparation method and an application thereof. Background technique [0002] Dioctyl sebacate, also known as dioctyl sebacate (bis(2-ethylhexyl)sebacate), bis-2-ethylhexyl sebacate, is light yellow liquid in standard state, slightly soluble in water, easily Soluble in ethanol and ether. It is the raw material for making nylon-610 fiber and nylon-9 fiber. Its esters are plasticizers in the plastics industry. The plasticizing performance is similar to DBS, but it has low volatility, good water extraction resistance, and excellent low-temperature flexibility and durability of the product. Low toxicity, toxicity coefficient T=1000. The United States and the Netherlands license the production of food packaging materials. Therefore, the research on its residual adsorption is worthy of attention...
