Decoquinate gel microsphere and its preparation method

[0022] Example 1

[0023] Weigh 1.1g CaCl 2 , Add distilled water to dissolve, dilute to 100ml, get CaCl 2 Aqueous solution. Take another 5g of decoquinate and 1g of sodium alginate, mix, add 194ml of distilled water, stir to make it fully mixed, drop (dropping rate of 100 drops/min) above CaCl 2 After stirring and reacting for 10 minutes in an aqueous solution, the formed gel microspheres are taken out, washed with distilled water, and dried to obtain decoquine gel microspheres with a particle size of 3.4 mm.

[0024] Example 2

[0025] Weigh 8.3g CaCl 2 , Add distilled water to dissolve, dilute to 500ml, get CaCl 2 Aqueous solution. Take another 1g of decoquinate and 5g of sodium alginate, mix, add 494ml of distilled water, stir to make it fully mixed, drop (dropping rate of 60 drops/min) above CaCl 2 After stirring and reacting for 24 hours in the aqueous solution, the formed gel microspheres were taken out, washed with distilled water, and dried to obtain decoquine gel microspheres with a particle size of 3.6 mm.

[0026] Example 3

[0027] Weigh 4.4g CaCl 2 , Add distilled water to dissolve, dilute to 200ml, get CaCl 2 Aqueous solution. Add another 3g of sodium alginate to 200ml of distilled water to obtain a 1.5% sodium alginate solution. Weigh 6g of decoquinate and add it to the above sodium alginate solution, stir to make it fully mixed; then the mixture is mixed under stirring conditions Add CaCl at a rate of 10 drops/min 2 In the aqueous solution, after 72 hours of reaction, the formed gel microspheres were taken out, washed with distilled water, and dried to obtain decoquinate gel microspheres with a particle size of 4.1 mm.
