| titleOfInvention | Fluorocarbon surfactant containing branch fluorocarbon chain and preparation method thereof |
| abstract | The present invention relates to fluorocarbon surfactant containing branch fluorocarbon chain and preparation method thereof.The method is with perfluor 2 methyl 2 amylene as initial feed, first and methyl benzyl bromine nucleophilic displacement of fluorine is made fluoro-containing intermediate 1, fluoro-containing intermediate 1 and chlorosulfonic acid react to obtain fluoro-containing intermediate 2 and surfactant I, and fluoro-containing intermediate 2 makes fluoro-containing intermediate amide 4 with amine condensation.Fluoro-containing intermediate amide 4 reacts with alkyl halide, sodium chloroacetate or biphenyl-benzyl dichloride respectively and prepares corresponding quaternary ammonium salt cationic fluorocarbon surfactant II, betaine type amphoteric fluorocarbon surfactant III and fluorine-carbon sufactant IV.Fluoro-containing intermediate 2 makes nonionic fluorocarbon surfactant V with alcohol condensation.The method has several advantages that raw material is easy to get, technique is simple, cheap, reproducible and product surface tension force performance is good. |
