Glucosyl containing rosinyl macroporous resin and preparation method thereof

Abstract

The invention discloses glucosyl containing rosinyl macroporous resin which is a lucosyl containing rosinyl macroporous resin acrylic acid gylcol ester-methylacrylic acid glucose ester copolymer. A preparation method comprises the following steps: (1) preparation of an aqueous phase; (2) preparation of an oil phase: placing a monomer in a container, adding a solvent, accelerating dissolution by an ultrasonic disperser, adding a crosslinking agent, a pore-foaming agent and an initiator after completely dissolution, and vibrating for 5-40 minutes under the ultrasonic effect to uniformly mix the oil phase; and (3) adding the uniformly mixed oil phase to a stirring reaction container, heating to react, and then, slowly adding the aqueous phase to the oil phase, wherein the mass ratio of the aqueous phase and the oil phase is (4-10):1, continuously heating, reacting at constant temperature and filtering to obtain a coarse product; and washing till the washing liquor is clean to obtain a product. The product provided by the invention is good in mechanical strength, and the basic raw materials rosin and glucose are natural and non-toxic and environmental-friendly. The resin can be used for separating and purifying hydrophilic food additives and medicines without causing secondary pollution.

Description

technical field [0001] The invention belongs to the field of polymer preparation, in particular to a glucose-based rosin-based macroporous adsorption resin and a preparation method thereof. Background technique [0002] Macroporous adsorption resin is a kind of polymer adsorption resin with no exchange group and macroporous structure. It has a good macroporous network structure and large specific surface area, and can selectively adsorb organic substances from aqueous solution through physical adsorption. . The adsorption of adsorbate by macroporous adsorption resin has the characteristics of simple adsorption steps, good selectivity, and fast separation speed, and has many advantages in practical applications, such as mild desorption conditions, high mechanical strength, good stability, and simple operation , strong anti-pollution ability, cheap, convenient regeneration, suitable for industrial production and other advantages. However, the macroporous adsorption resin has...

AI Technical Summary

Problems solved by technology

However, these monomers and solvents are toxic reagents, which are likely to cause secondary pollution in practical applications.

Unreacted monomers and solvents are not friendly to the environment and the resin is difficult to degrade, which causes post-processing problems; ③Most of the traditional macroporous adsorption resins use hydrophobic styrene or acrylic as monomers for synthetic resins, so that Can not meet the adsorption requirements of some hydrophilic macromolecules

There are also reports of some hydrophilic macroporous adsorption resins, and these hydrophilic macroporous adsorption resins generally use polysaccharide gel as the matrix, which has the disadvantages of poor mechanical strength, low pressure, and easy decomposition.
