Embodiment Construction

[0005] Take 7g of potato starch and add water to make a paste, and activate it at pH=10, 80°C for 0.5h. Add 100ml of vegetable oil, 0.4gspan60, and heat to dissolve at 60°C in a three-necked flask. Add the activated starch and stir at high speed. After the starch is fully dispersed, add a certain amount of cross-linking agent and initiator to react at a certain temperature for 4 hours.

[0006] Pour out the vegetable oil, fully wash the product with ethyl acetate, filter under reduced pressure, and dry the obtained product under reduced pressure at 60°C to finally obtain white to light yellow starch microspheres with a particle size of 50 μm and a narrow distribution range. The adsorption amount of methylene blue is about 2g / g (the adsorption amount of different model drugs is different).

Abstract

The present invention relates to a method for synthesizing starch microsphere as adsorption agent, and it is characterized by that the starch microsphere can be synthesized at a certain temperature, in a certain reaction time, under the action of high-effective catalyst and surfactant in the dispersing agent, and the whole reaction can be made within 4 hr, and the sphere-forming time is within an hour. Said invented microsphere can be used as medicine carrier, adsorption agent of several substances of perfume compound, etc. reinforcing agent of weight-reducing food and paper and sewage treating agent, etc.

Description

(1) Technical field [0001] The invention relates to a chemical product, in particular to a method for synthesizing an adsorbent, that is, a method for synthesizing starch microspheres. (2) Background technology [0002] The current starch microspheres take too long to synthesize (generally more than 10 hours), and the monomers and additives used are also expensive, so the cost is too high. For a long time, it can only be used as a drug carrier, but cannot Other fields have been fully applied. (3) Contents of the invention [0003] The invention solves the problems of long synthesis time and high cost of starch microspheres. The present invention is accomplished through the following steps: (1) adding water to ordinary starch to make a paste, and then activating it for 0.5h at pH=10 and starch activation temperature of 80°C to obtain the ready-to-use refined starch: (2) selection Appropriate acrylamide monomers to make cross-l...
