Embodiment 1

[0053] Accurately measure 103.17g of diethylenetriamine into a 500mL three-necked flask, and add dropwise a mixture of 86.09g of methyl acrylate and 100mL of methanol in an ice bath. After continuous stirring for 16 hours, a light yellow liquid was obtained. The product was transferred to an eggplant-shaped flask of a rotary evaporator, evacuated by a circulating water vacuum pump, condensed under reflux, rotated at a high speed, and reacted at a water bath temperature of 60° C. for 1 h. Then transfer to the oil bath, start from 100 °C, increase the oil bath by 20 °C every hour for 3 hours, and get the final product of amino-terminated hyperbranched polyamide HBP-NH 2 , and then add the same mass of deionized water to configure HBP-NH with a mass fraction of 50% 2 spare.

Embodiment 2

[0058] The experimental method of amino-terminated hyperbranched polyamide chlorinated modified peanut shells in the present embodiment is:

[0059] Accurately weigh 2g of chlorinated peanut shell powder, pour it into a 150mL three-necked flask equipped with a condenser and a stirrer, then add 60mL of DMSO, heat in a water bath to 60°C, slowly add 4mL of hyperbranched polymer HBP-NH2 dropwise, and maintain Continue to stir and react at this temperature for 14 hours to obtain a dark brown liquid product in a natural state. Wait until its temperature drops to normal temperature, pour 100mL of cold water into it, and suction filter overnight.

Abstract

The invention provides amino-terminated hyperbranched polyamide chlorinated peanut shells and application thereof in separation and detection of sunset yellow in food. The amino-terminated hyperbranched polyamide chlorinated peanut shells have a high adsorption and separation effect on the sunset yellow and are excellent in cyclic regeneration performance.

Description

technical field [0001] The invention belongs to the technical field of chemistry, and in particular relates to a chlorination-modified peanut shell of an amino-terminated hyperbranched polyamide and an application thereof. Background technique [0002] Hyperbranched polymers have a "defective core-shell" spatial structure with multiple terminal groups, high chemical reactivity, and are easy to modify. Compared with the corresponding linear polymers, they have special properties and show broad application prospects in many fields . Hyperbranched polymers not only have similar physical and chemical properties to dendritic polymers, but also require milder synthesis conditions than dendritic polymers, do not require multi-step synthesis and purification, and have a simple synthesis process and low cost. Realize " one pot cooking type " synthetic, be helpful for realizing industrialization. Therefore, hyperbranched polymer more and more replaces dendritic macromolecule and beco...
