It is obtained by the reaction of 3-chloro-1-propylene and magnesium. Place magnesium chips in the reaction bottle first, then drop the solution of anhydrous 3-chloro-1-propylene and anhydrous diethyl ether, then add a small particle of iodine and stir, drop 5% of cold hydrochloric acid solution to dissolve magnesium chloride in the solution, separate out the ether layer, distill, wash with water, dry with calcium chloride, and then evaporate the diethyl ether and 3-chloropropene through fractionation, and collect the 59-60 ℃ fraction, 5-Adiene.
