Preparation of 3-Bromothiophene   CAS NO: 872-31-1

2,3, 5-tribromothiophene zinc powder acetic acid water and extraction agent were put into the reducing kettle at one time according to the feeding ratio, and stirring was started.  After stirring about 30min, the temperature was raised to reflux and maintained steady reflux for 6~8h, and then sampling analysis was performed to determine whether the reaction reached the end point.

After the reaction, the distillate was first distilled by steam, then the distillate was added to the extractant for extraction, and the extractant was recovered by distillation.Finally, the fractions of 159~161 are received, and the product 3-Bromothiophene   CAS NO: 872-31-1 is obtained .The yield of about 90% .
