Embodiment 1
[0020] (1) Loofah pretreatment: loofah is derived from loofah fruit, which is obtained by peeling and removing the core, cutting loofah into small pieces, washing with water, drying in vacuum, crushing, and sieving with a 60-mesh sieve;
[0021] (2) Alkaline treatment of loofah: 50% of the total mass of loofah with pulverization, mixed with 5% NaOH solution and 20% ethanol solution to azeotrope for 0.5h, washed with deionized water to pH after cooling is 7, dried at 60°C after suction filtration to obtain alkalized loofah;
[0022] (3) Acylated loofah: Add 5.0g of alkalized loofah and 20g of chloroform into a stoppered conical flask, stir for 10min under the protection of argon, add 2g of acryloyl chloride dropwise with a constant pressure funnel, drop After stirring for 10 minutes, add 3.5 mL of triethylamine dropwise with a constant pressure funnel. After the dropwise addition, stir at room temperature for 24 hours, filter, wash with chloroform and methanol in turn, and dry ...
