Problems solved by technology
Existing resins used for amino acid extraction do not process toluene as a porogen after production, but only carry out vacuum drying. Because the temperature of vacuum drying is low, and the boiling point of toluene is higher than 100, it is not very good. After being taken out by vacuum drying, the existence of toluene as a porogen will seriously affect the adsorption capacity of the resin in the later stage, and it has a pungent smell and toxicity

Embodiment Construction
[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0014] A kind of production technology of amino acid adsorption resin, comprises the following steps successively,
[0015] (6) Prepare the water phase substance with distilled water: it is made with ammonium bisulfite whose concentration is 1% polyvinyl alcohol and 4.5%;
[0016] (7) Prepare the organic phase: take the crosslinking agent and the polar monomer and mix them in a ratio of 5:1, and add toluene as a porogen;
[0017] (8) Resin preparation: raise the temperature of the water phase to 35°C, pour the organic phase and di-tert-butyl dicarbonate into the water phase while stirring, heat up to 95°C after mixing, and polymerize for 3.5 hours. The mass ratio of aqueous phase and organic phase is 20:2, and di-tert-butyl dicarbonate accounts f...

The invention discloses a production method of an amino acid adsorption resin, and belongs to the field of resin technology. The production method comprises following steps successively: (1) a water phase substance is prepared with distilled water; (2) an organic phase substance is prepared, wherein a cross-linking agent is mixed with a polar monomer, and methylbenzene is added as a pore-foaming agent; (3) resin is prepared, wherein the water phase substance is heated to 30 to 40DEG C, the organic phase substance and di-tert-butyl dicarbonate ester are added with stirring, after mixing an obtained mixture is heated to 90 to 100 DEG C, and is subjected to polymerization for 3 to 4h, mass ratio of the water phase substance to the organic phase substance is controlled to be 20:1 to 20:4, and the weight of di-tert-butyl dicarbonate ester accounts for 0.1 to 1% of the total of the obtained mixture; (4) the pore-foaming agent is removed, wherein an obtained resin is immersed in diethyl ether for 5 to 6, and then is washed with clean water for a plurality of times; and (5) post-processing is carried out, wherein an obtained product is subjected to vacuum drying at a temperature of 60 to 80 DEG C under a vacuum degree of 100Pa. Methylbenzene, which is taken as the pore-foaming agent, can be completely removed in the production processes; the production method is friendly to the environment, and is capable of saving energy; and the obtained amino acid adsorption resin possesses better adsorption capacity.
Description
Technical field: [0001] The invention relates to the technical field of resins, in particular to a production process of amino acid adsorption resins. Background technique: [0002] Adsorption resin is a resin adsorbent characterized by adsorption and has a porous three-dimensional structure. It is a newly developed porous resin in the field of polymers in recent years. It is made of monomers such as styrene and divinylbenzene in the presence of organic solvents such as toluene. Small circles like fish roe are prepared by suspension copolymerization. ball. Adsorbent resins are often used in the fields of sewage treatment and extraction. Existing resins used for amino acid extraction do not process toluene as a porogen after production, but only carry out vacuum drying. Because the temperature of vacuum drying is low, and the boiling point of toluene is higher than 100, it is not very good. After being taken out by vacuum drying, the existence of toluene as a porogen will ...
