With metallic sodium, lauryl alcohol and 3- chloro- 2- hydroxy propyl triethyl ammonium chloride (CTA) as raw materials, cationic surfactant 3- alkoxy- 2- hydroxy propyl triethyl ammonium chloride (DPAC) was obtained. Through the orthogonal experiment the optimum synthetic technology conditions were as follows: tetrahydrofuran as solvent, dosage of 80 mL (based on 0.1 mol sodium alcoholate);n(RONa)∶n(CTA)=1∶1;reaction temperature was 60℃, reaction time was 6 h, in this situation, the yield of product was 86.1%. Structure of the product was confirmed by FT-IR and elemental analysis. Under 25℃ measured the γcmc of DPAC was 36.37 mN/m, critical micelle concentration CMC was 1.80 ×10-3 mol/L. Product used in oxygen alkylation reaction, carbon alkylation reaction and aromatics oxidation reaction showed good phase transfer catalytic effect.
