4) hydrophobic groups • The order of lipophilicity of surface acitve agents with different hydrophobic groups is as follows: Fatty alkane 脂肪族烷烃 >cyclane 环烷烃 >fatty alkene 脂肪族烯烃 >fatty aromatic hydrocarbon 脂肪族芳烃 > aromatic hydrocarbon 芳香烃 >hydrocarbon with weak hydrophilic groups 带弱亲水基团的烃
source and pollution of surface 1. source: active agent • 1960s, already largely used in detergent industry • 1999, global annual use reached 9.3 million t • 2000, global annual use reached 10.8 million t • 2005, global annual use reached 12.5 million t • A large portion of used surface active agent enters waste water. • The problem of the degradation of surface active agent requires attention from environmentalists.
