The present patent relates to a method for preparing sodium cocoyl isethionate. The method takes coconut oil as raw material, uses quaternary phosphonium salt ionic liquid as solvent and catalyst, and reacts with sodium isethionate by one-step method to generate coconut oil. Sodium oleyl isethionate. The method has the advantages of low synthesis cost, simple process, mild reaction conditions, shortened reaction time, reduced reaction temperature, high conversion rate, good selectivity, green catalyst, recyclable and reusable, less three wastes, and is a green and environmentally friendly preparation method. |
