Synthesis of Reactive Surfactant of Mono-alkyl phosphates
Abstract:
The synthesis technology for mono-alkyl phosphate reactive surfactants was studied and the optimum conditions of preparation were determined on the basis of experimental results.Firstly,ω-hydroxy-decyl-methacrylate (compound Ⅰ) was synthesized when the mole ratio of methacrylic acid to 1,10-decanediol was 1:1.75 with p-toluene sulphonic acid as catalyst and at 80℃ for 5 h.Secondly,ω-phosphate-decylmethacrylate (compound Ⅱ) was obtained by the reaction of compound Ⅰ with P2O5 at the mole ratio of 2:3,the reaction temperature was 60~70℃,the reaction time was 5 h;and then,the hydrolysis reaction time was 1 h.Finally,the product was got by neutralizing the compound Ⅱ with KOH.The yield of alkyl monophosphate reaches to 97.91%.It was found that the emulsifying power of the product was better than those of SDS and DNS-86,the critical micell concentration of the product was 0.036 mol/L.
