Embodiment 1
[0030] 1. Transesterification reaction: Add 500 parts of rapeseed oil and 90 parts of methanol into a 1000 mL four-necked flask equipped with a thermometer, a stirring device and a reflux condenser, raise the temperature to 80°C, add 5 parts of p-toluenesulfonic acid, and keep stirring Reacted for 4 hours, after the reaction was completed, the product was left to stand and layered, the upper layer was rapeseed oil fatty acid methyl ester, the lower layer was glycerol, and the lower layer was released to obtain rapeseed oil fatty acid methyl ester; Add 200 parts of rapeseed oil fatty acid methyl ester and 50 parts of ethanolamine to a 500 mL four-neck flask with a stirring device and a reflux condenser, raise the temperature to 140°C, and react for 3 hours at 0.04Mpa; 3. Quaternization reaction: cool down to 55°C, add 1.25 parts of triethylamine, add 122 parts of ETA aqueous solution dropwise into the reaction kettle, keep warm and stir for 4 hours, after the reaction is comple...
