Synthesis process of 1, 7-dichloro-4-heptanone

The invention relates to the field of organic synthesis, in particular to a synthesis process of 1, 7-dichloro-4-heptanone, which comprises the following steps: (1) adding hydrochloric acid into a reactor, stirring, and adding a catalyst in batches; (2) heating, dropwise adding a dicyclopropyl ketone/organic solvent mixed solution, and after dropwise adding, controlling the temperature to react; and (3) cooling, layering, taking an organic phase, and carrying out reduced pressure concentration to remove the solvent, thereby obtaining the 1, 7-dichloro-4-heptanone. The synthesis process of the 1, 7-dichloro-4-heptanone, provided by the invention, is short in route, few in by-products and simple in reaction and post-treatment. The method is novel in route, simplifies the process, overcomes the defects in the prior art, and has industrial value. 本发明涉及有机合成领域，尤其涉及一种1,7-二氯-4-庚酮的合成工艺，包括如下步骤：(1)反应器中加入盐酸，搅拌，分批加入催化剂；(2)加热，滴加双环丙基酮/有机溶剂混合溶液，滴毕，控温反应；(3)降温，分层，取有机相，减压浓缩除去溶剂，得到1,7-二氯-4-庚酮。本发明提供的1,7-二氯-4-庚酮的合成工艺，路线简短，副产物少，反应和
