5-Chloro-1-pentene Use and Manufacturing

In a 2000 ml four-necked flask equipped with a mechanical stirrer, a dropping funnel, a reflux condenser and a thermometer, 200 g (2.33 mol) of 4-penten-1-ol, 2 g of bismuth trioxide and 700 g of pyridine were added.The temperature of the system was lowered to 0 ° C with ice-salt bath with stirring. At this point, 238 g (2 mol) of thionyl chloride was added dropwise to the system with a dropping funnel.Control the rate of dropping to ensure that the material temperature does not exceed 5 , dropping the end, remove the ice salt bath. Naturally heated to between 10-30 , the reaction was stirred for 72 hours.When the temperature exceeds 30 , use ice salt bath to cool below 30 . After the reaction was completed, the mixture was filtered through a Buchner funnel and the filter cake was taken as a catalyst and pyridine hydrochloride. The filter cake was rinsed twice with 200 ml of acetone.The combined filtrate and washings, poured into 1500ml of distilled water, allowed to stand, separate the lower reservoir.The oil layer was further washed with distilled water to neutrality, and then distilled under reduced pressure in a water pump to collect the distillate fraction (vacuum 255 mmHg) at a head temperature of 88-95 ° C.199g colorless liquid was obtained in a yield of 95.22percent. Gas chromatography detection of content of 98.27percent.
