Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical production technology, and in particular to a device for adding bromine in the production of bromoacetaldehyde diethanol. Background Technology

[0002] In the pharmaceutical, pesticide, and fine chemical industries, bromoacetaldehyde diethanol is an important organic intermediate widely used in the synthesis of antibacterial drugs, insecticides, and functional materials. Its production process typically involves the bromination reaction of acetaldehyde diethanol. This reaction requires precise control of bromine addition under low-temperature conditions to avoid side reactions (such as over-bromination or oxidation) and to improve product yield. Bromine is highly volatile and corrosive; traditional glass dropping funnels or ordinary metering pumps are prone to Br2 leakage due to poor sealing, causing safety hazards and raw material waste. Bromine is also highly corrosive to metal components; long-term use can lead to seal failure or pipeline blockage, increasing maintenance costs. Therefore, we have redesigned a bromine dropping device for the production of bromoacetaldehyde diethanol. Utility Model Content
