| titleOfInvention | A kind of perfluoropolyether surfactants and preparation method thereof |
| abstract | The present invention relates to a kind of perfluoropolyether surfactants, preparation method is：Perfluoropolyether sulfuryl fluoride, catalyst are first added in a kettle, two aminates are added while stirring, heats reaction kettle, is cooled to room temperature after reaction；Chloracetate solution, water are added in aforesaid reaction vessel later, heating stirring obtains perfluoropolyether surfactants after reaction.Perfluoropolyether surfactants preparation method of the present invention is simple, and stable processing technique is easily operated；Reaction condition is mild, and energy consumption is small, and equipment requirement is simple；High conversion rate, the discharge of production process non-toxic by-products is pollution-free, has good environment protecting. |
