Twelve new ethoxylated mono alkyl bisphenol surfactants were prepared. These surfactants have a general formula as E(X) B(Y) M(R) wherein, the E(X) is the degree of ethylene oxide units, the B(Y) is the bisphenol which based on acetophenone (BAC), cyclohexanone (BCH), or acetone (BA) and R is the alkyl chain of fatty acids (decanoic, lauric, myristic, palmitic, stearic, oleic, linoleic, or linolinic). The chemical structures were confirmed using FTIR. The surface active properties for these surfactants were calculated using surface tension measurements. They were tested as corrosion inhibitors for carbon steel alloy in 2 M HCl solution the inhibition efficiency was evaluated using potensiostate Wenking 81 M. The efficiency of inhibitors was discussed on the light of their chemical structures such as alkyl chain length, degree of unsaturation, ethoxylation, bisphenol skeleton, and structure modification. From the data obtained it was found it was found that a strong relation between the surface active properties and the corrosion inhibition efficiency, also, the results clear that the corrosion inhibition efficiency increases with increasing the degree of unsaturation, ethoxylation, and alkyl chain length. Regarding to the bisphenol skeleton, it was noticed that the minimum inhibition efficiency was exhibited by bisphenol BCH, but the maximum efficiency was obtained by bisphenol BAC. As a result of these parameters, the 87.68% corrosion inhibition efficiency was obtained by inhibitor E(43) BCHMLL and 93.32% efficiency was exhibited by E(43) BACMLL. |
