| titleOfInvention | A kind of preparation method of composite starch base |
| abstract | The invention discloses a method for preparing a composite starch base, which specifically includes the following steps: S1. Modification of chitin: calculating an appropriate amount of chitin according to parts by weight, vacuuming and passing nitrogen, and then adding an appropriate amount of anhydrous tetrahydrofuran and Triethylamine, stir evenly, then drop an appropriate amount of acryloyl chloride into it, continue to react for 3 hours after the dropwise addition, the filtered filter residue and filter residue are washed three times with water, and then placed in an oven for drying, and the drying time is 2- 4 hours, and the drying temperature is 50°C-60°C, and the invention relates to the technical field of starch-based preparation. The preparation method of composite starch base has high conversion rate of reagents, all raw materials are produced into products, no three wastes are discharged, green environmental protection and no pollution, good reaction uniformity in the preparation process, short reaction time, low energy consumption, hydroxyl, ester group, carboxyl group, carboxymethyl group and other groups, the synergistic effect of each group, as well as the synergistic effect of natural polymers and synthetic polymers. |
