110-52-1 - Application:

1,4-Dibromobutane (CAS: 110-52-1) is used as an intermediate involved in the synthesis of active pharmaceutical ingredient and other organic compounds. Organic synthesis intermediates. 1,4-Dibromobutane is used for the manufacture of aminophylline, kebiqing, expelling Qingjing, etc. 1,4-Dibromobutane is used as a catalyst in the polymerization of 2-oxazolines. Also used in the synthesis of cholinesterase inhibitors used against Alzheimer’s disease.

110-52-1 - Production Method:

1. 1,4-Dibromobutane is derived from tetrahydrofuran by ring opening and bromination. Hydrobromic acid was added to the reaction Pan, tetrahydrofuran was added dropwise under stirring, and sulfuric acid was added dropwise, and the temperature was controlled to be below 50℃. After completion of the reaction, the mixture was stirred for 1H. The lower solution was separated by cooling, washed with soda ash solution until neutral, dried with anhydrous calcium chloride, and filtered to obtain the finished product.

2. Derived from the bromination of 1,4-Butanediol. Hydrobromic acid was added to the reaction pot, cooled to 10℃ with stirring, and sulfuric acid was added dropwise. After completion of the addition, 1,4-Butanediol was further added dropwise at a temperature not exceeding 15℃, and the mixture was stirred for half an hour. Incubation was performed for 6h at 100-110℃. Cool to room temperature, separate the lower liquid, wash with soda ash solution to neutral. After Dehydration of calcium chloride, 1,4-Dibromobutane was obtained by filtration.

110-52-1 - Storage and Transportation:

Store in a cool and ventilated warehouse, away from the fire. Keep the container sealed and stored away from the oxidant. Emergency handling equipment and appropriate containment materials should be provided.
