Abstract

The invention discloses rosinyl anion macroporous adsorption resin and a preparation method thereof, and the rosinyl anion macroporous adsorption resin is prepared by taking dimethylaminoethyl methacrylate as a monomer and hydrogenated rosin (beta-acryloyloxyethyl) ester as a cross-linking agent through a suspension polymerization method. The rosinyl anion macroporous adsorption resin is a spherical porous material, the average pore size is 3-10 nm, the specific surface area is 5-10 m < 2 > / g, the resin is non-toxic, green and environment-friendly and uniform in particle, and a functional group is of a tertiary amine anion structure. The rosin-based anion macroporous adsorption resin has the unique advantage of separating substances with negative charges, so that the rosin-based anion macroporous adsorption resin can be used for separating hexose pigments, Maillard pigments or other pigments with negative charges in food.

Description

technical field [0001] The invention belongs to the field of chemical synthesis, and in particular relates to a rosin-based anionic macroporous adsorption resin and a preparation method thereof. Background technique [0002] Ionic macroporous adsorption resin is a kind of loose porous polymer material, which has become a popular common polymer separation agent due to its good separation properties such as adsorption, selectivity and desorption. At present, the raw materials of macroporous adsorption resins commonly used in the market are styrene or acrylic acid. Through polymerization, a skeleton with a three-dimensional network structure is formed, and then different types of chemically active groups are introduced into the skeleton to make the resin have different functions. In practical applications, ionic macroporous adsorption resins are widely used in water treatment, food coloring decolorization, separation of natural and synthetic drugs and other industries. At pres...
