Synthesis of 3-Fourteen Alkoxy-2-hydroxypropyl Triethyl Ammonium Chloride and Inhibiting Corrosion Performance

Abstract

3-Fourteen alkoxy-2-hydroxypropyl triethyl ammonium chloride (TPAC) was synthesized by using tetradecyl alcohol, triethylamine, epichlorohydrin, and so on. The surface properties of product such as critical micelle concentration and surface tension were studied. The corrosion inhibition performance of product to A3 carbon steel was tested. Given the conditions of acidic medium, the immersion lasted for 72 h, under 25°C, and the concentration of product is 0.70 m mol/L; the corrosion inhibition rate is 95.21% over A3 steel. The result showed that TPAC has good surface activity and capacity in inhibiting corrosion.
