Abstract: Four kinds of fatty alcohol ether propionate were synthesized via addition and saponification with fatty alcohol (octanol,decanol and dodecanol),fatty alcohol polyoxyethylene ether (AEO7) and tert-butyl acrylate as raw materials.Structure of the products was characterized by FTIR,1HNMR and ESI-MS methods.The addition reaction parameters were optimized via a series of experiments as follows:n(fatty alcohol (AEO7)):n(tert-butyl-acrylate):n(sodium methoxide)=1:3:0.02;reaction temperature,50 ℃;reaction time,6 h.The products show good surface activity.With increasing of the carbon chain length,their cmc,γcmc and Amin decreases while Γmax and pc20 increases.However,the results were reversed as the fatty alcohol molecules are ethoxylated.

Key words: alcohol ether propionate, fatty alcohol, fatty alcohol polyoxyethylene ether, tert-butyl acrylate, synthesis, surface activity
