Based on fatty alcohol polyoxyethylene ether（AEO-3, AEO-5, AEO-7）with different ethylene oxide (EO) structural unit, 1, 2-ethylene glycol, 1, 3-propanediol, 1, 4-butanediol and maleic anhydride, anionic-nonionic Gemini surfactants were synthesized. The structural formula was abbreviated as follows: ANG_n-m-n, n=3、5、7, indicating AEO-3, AEO-5 and AEO-7 respectively, m=Ⅱ、Ⅲ、Ⅳ, indicating the spacer length of ethylene glycol, propanediol and butanediol respectively. The foaming property was determined for the 9 kinds of anionic-nonionic Gemini surfactants of polyalkoxylated ether sulfonate. The results showed that the foaming height increased with increasing spacer length of the Gemini surfactant, when the dosage of surfactant was 0.2% and EO unit was same. The foaming height increased with increasing EO structural unit, when the spacer length was same. In generally, the shorter spacer length, the better stability of foam was. The influence of salt concentration on the foaming properties of ANG 7-Ⅳ-7 was investigated. The foaming height and half-life (t_1/2) increased first and then decreased with increasing salt concentration. When the concentration of NaCl reached 20 g/L, the foaming height was 167.2 cm and t_1/2 was 1163 s. When the concentration of CaCl₂ reached 1 g/L, the foaming height was 161.4 cm and t_1/2 was 1131 s. When the temperature increased, the foaming height increased first and then decreased with 151.5 cm maximum value at 50℃, and t_1/2 decreased gradually. When the volume fraction of alcohol increased, the foaming height and t_1/2 increased first and then decreased. The optimum dosage of ethanol, isopropanol and n-butanol was 4%, 3% and 2%, respectively.
