Abstract
1,4-dichloro-2-butyne was one of the important intermediate which was widely used in fields like medicine,pesticide,aromatics and polymer material.In this paper,1,4-dichloro-2-butyne was obtained by using 2-butyne-1,4-diol react with thionyl dichloride under the existence of pyridine.We have test the boiling point of the product after its purification,and have confirmed the structure by means of IR、1HNMR and MS spectrum.We have also measured the UV property of the product which showed that the λmax of 1,4-dichloro-2-butyne altered like "W" when increasing the polarity of the solvent we selected.
