Thionyl Chloride → HCID 14802144, compound

Participants

Reaction Steps

Excess thionyl chloride and a few drops of DMF are added to monobutyl succinate. The reaction starts with evolution of gas. The mixture is stirred overnight with the exclusion of moisture and the excess thionyl chloride is then removed by distillation at normal pressure. The crude product which remains is fractionally distilled at 0.05 mbar and the pure product is obtained at about 70° C. In the IR-spectroscopic characterization, the product has bands at 1,800 cm-1 (acid chloride) and 1,740 cm-1 (ester) of equal intensity.
