Embodiment 1
[0052] Embodiment 1 The preparation of polyisobutylene succinic anhydride-triethanolamine
[0053] 33 g of polyisobutylene succinic anhydride was added to a four-necked flask equipped with a condenser, a stirring paddle, a thermometer, and a nitrogen inlet pipe, and the temperature was raised to 110°C. Add 6g of triethanolamine (TEA), pass nitrogen, continue to heat up to 160 ° C, and react until the acid value no longer changes, and the product is obtained. The infrared spectrum analysis of the product is shown in the appendix Figure 1a and 1b , Figure 1a Be the infrared spectrogram of raw material isobutylene succinic anhydride, Figure 1b IR spectrum of the product.
Embodiment 2
[0054] Example 2 Preparation of superabsorbent resin
[0055] Weigh 2g of natural cellulose powder into a three-neck flask filled with 40ml of distilled water, install a stirring device, a condensation device, and a nitrogen protection device, and then pass through nitrogen protection, heat the water bath to 95°C and stir for 2 hours, cool down to 65°C, add trigger Add 0.05g of ammonium persulfate, stir and disperse for 20 minutes, add 8g of acrylamide and stir, then add cross-linking agent N,N-methylenebisacrylamide, react for 3 hours, then wash with distilled water and methanol several times, at 70 °C, dried to constant weight, crushed into powder, figure 2 Infrared spectrum of superabsorbent resin.
Embodiment 3
[0056] Example 3 Preparation of Herbal Plant Mixture Extract
[0057] Put 25g of Daxueteng, 30g of peach branches, 20g of Baibu, 25g of betel nut, 20g of toon bark, 25g of Vitex leaves, 30g of pepper, 25g of flavescens, 20g of garlic, 25g of Agrimony, 35g of Jiulixiang, 40g of tangerine peel, 30g of rue, 25g of inulin and 20g of benzoin were crushed respectively, passed through a 20-mesh sieve, sent into a mixer and stirred evenly to obtain a mixture, which was added to 2kg of ethanol with an alcohol concentration of 80%, soaked for 36 hours, and percolated at a rate of 3ml per minute. Slowly percolate, collect the percolate, concentrate under reduced pressure to obtain a dry paste, and crush it into powder.
