盐酸介质中松香基季铵盐Gemini表面活性剂对碳钢的缓蚀性能
CORROSION INHIBITION EFFECT OF BISQUATERNARY AMMONIUM SALT OF ROSIN GROUP TO MILD STEEL IN HYDROCHLORIC ACID
摘要
Abstract
Inhibition of a series of bisquaternary ammonium surfactants of the rosin group, DDMBDAB、 DDMHDAB、 DDMHPDAC、 DDMXDAB, on mild steel in hydrochloric acid medium were investigated by measuring weight loss and polarization. Thermodynamics of inhibition of four bisquaternary ammonium surfactants was studied. Data indicated that the bisquaternary ammonium surfactants were excellent inhibitors against mild steel corrosion in hydrochloric acid. It was found that adsorption to the surface of mild steel is physical adsorption and is an endothermic process.关键词
