Preparation and uses of 1,5-Hexadiene: This chemical can be prepared by 3-chloro-1-propylene and magnesium. Drop Anhydrous 3-chloro-1-propylene and anhydrous ether solution into the reaction flask in the presence of magnesium chips, then add iodine with stiring. Drop 5 % cold hydrochloric acid solution to dissove the magnesium chloride. Skim the solution and get the ether extract, and then distillate, washing and dry. Collect 59-60 °C distillation cut after fractionation, and that is the 1,5-Hexadiene. And this chemical is usually used in the organic synthesis.
