In this thesis, biomass cardanol , ethylene oxide, chloroacetic acid and sodium hydroxide as the raw material , passes through the ring-opening polymerization reaction , basified reaction carboxymethylation reaction , and acid - base neutralization reaction to prepare a series of cashew phenol polyoxyethylene ether carboxylic acid salt (CPEC) anion - non-ionic surface active agent . Its structure was characterized by infrared spectroscopy and elemental analysis , and they are water-soluble , table / interfacial tension , wetting properties , the foam properties and salt tolerance . Measured Krafft point of the synthesis of CPEC to measure its water-soluble strong or weak , the results show that : the more the number of ethylene oxide , more hydrophilic , lower Krafft point , water solubility enhancement ; spinning drop interfacial tension by hanging the dropwise Determination product CPEC at 25 ℃ pure aqueous solution and the surface tension of the aqueous solution of NaCl , by the surface tension with the concentration curves obtained the CPEC-8, 10,12,14 of the critical micelle concentration (cmc) , and the critical micelle corresponds to the concentration of the surface tension (γ cmc ) as 9.30,8.50,8.10,7.71 mmol / L and 28.38,28.60,30.40,30.00 mN / m; CPEC aqueous solution was measured by the Ross-Miles method foam performance, results showed that : as CPEC increasing concentration of the foaming and foam stabilizing capacity is gradually increased and reaches a certain concentration little change , as the temperature increases , CPEC foaming and foam stabilizing capacity corresponding decline , with Ca2 , Mg2 increase in the concentration of the CPEC foaming and foam stabilizing ability declined slightly , with the increase in the amount of NaCl , the CPEC foaming and foam stabilizing ability first increases and then decreases ; determination of the CPEC aqueous solution in a hydrophilic wetting properties, in the resistance on the slide contact angle decreases, the increase of the with CPEC mass concentration enhancement of the wetting properties on glass slides , the ability of the hydrophilicity of the hydrophilic surface ; CPEC the salt resistance were measured , with significant oxygen ethylene increase in the number the better the performance of CPEC Salt ; CPEC Salt better performance with increasing temperature ; determination of the interfacial tension between the the CPEC aqueous solution of n-alkanes in the sodium chloride concentration 6g / L, n-pentanol and the volume concentration of 1.5% , CPEC -14 aqueous solution and n- dodecane formed interfacial tension 0.0888mN / m.
