季铵化反应合成得到系列季铵盐，并以合成得到的季铵盐为原料，添加适当的氧化剂及溶剂，经1,3-偶极环加成反应（二聚反应）得到系列吲哚嗪衍生物，并对各自的粗品进行提纯处理。通过红外线光谱以及质谱等表征方法对合成化合物的结构进行确认，并对合成的吲哚嗪衍生物的缓蚀性能进行评价。该数据为4-Cl取代吲哚嗪衍生物的红外光谱数据。

The quaternization reaction was synthesized to obtain a series of quaternary ammonium salts, and the synthesized quaternary ammonium salts were used as raw materials to obtain a series of indolizine derivatives by 1,3-dipolar cycloaddition reaction (dimerization) with the addition of appropriate oxidizing agents and solvents, and the purification of the respective crude products was carried out. The structures of the synthesized compounds were confirmed by infrared spectroscopy as well as mass spectrometry and other characterization methods and the corrosion inhibition properties of the synthesized indolizine derivatives were evaluated.The data are infrared spectral data of 4-Cl substituted indolizine derivatives.
