Embodiment 1 10
[0030] The synthesis of embodiment 1 lauryl glucoside whipping agent 1
[0031] Synthesis of dodecyl glucoside carboxylate: Add 22.8g (0.10mol) of dodecyl glycoside into the three-neck flask, dissolve 10.0g (0.1mol) of solid succinic anhydride in 100mL acetone and place in the dropping funnel, Under nitrogen protection, succinic anhydride solution was added dropwise in a water bath at 40°C, stirred for 8 hours, and cooled to obtain the product.
[0032] Amidation reaction: Add 0.1mol of the above-mentioned dodecyl glucoside carboxylate into the three-necked flask, then add ethanol to dissolve, heat to 50°C, and slowly add N,N-dimethylpropylenediamine dropwise through the dropping funnel 10.7g (0.105mol) reacted to form ammonium salt, and after 2h, excess N,N-dimethylpropylenediamine and ethanol solvent were removed by distillation under reduced pressure. After there is no distillate, raise the temperature to 190°C for amidation reaction, stop the reaction after no new condens...
