Degradable surfactant and preparation method thereof

In order to solve the problem that a substitute of an existing C8 fluorinated surfactant cannot give consideration to both degradability and surface activity, the invention provides a degradable surfactant which has the following structure: # imgabs0 #, in which R1 is selected from perfluoroalkyl or...

Zusammenfassung:In order to solve the problem that a substitute of an existing C8 fluorinated surfactant cannot give consideration to both degradability and surface activity, the invention provides a degradable surfactant which has the following structure: # imgabs0 #, in which R1 is selected from perfluoroalkyl or oxa-fluorine chains with 2-7 carbon atoms, R2 is selected from hydrocarbon alkyl chains with 1-6 hydrogen atoms or carbon atoms, n is an integer of 1-5, R3 is an integer of 1-5, and n is an integer of 1-5. R4 is selected from hydrocarbon alkyl chains with the hydrogen atom number or the carbon atom number being 1-3, R5 is selected from-CH2-,-CH2CH2-,-CH2CH2CH2-or-CH2CH (OH) CH2-, and A is selected from-CO2 or-SO3. 为克服现有C8类氟表面活性剂的替代品存在无法兼顾可降解性和表面活性的问题，本发明提供了一种可降解型表面活性剂，包括以下结构：#imgabs0#其中，R1选自碳原子数2～7的全氟烷基或氧杂氟链，R2选自氢原子或碳原子数为1～6的碳氢烷基链，n为1～5的整数，R3，R4选自氢原子或碳原子数为1～3的碳氢烷基链，R5选自-CH2-,-CH2CH2-,-CH2CH2CH2-或-CH2CH(OH)CH2-，A选自-CO2或-SO3。
