Used for the synthesis of butynediol in the BDO process by aldehyde acetylene method (low pressure), it is a copper bismuth catalyst supported on magnesium silicate, suitable for ISP (three-dimensional process) alkyne aldehyde synthesis reaction.

High activity, high selectivity

Reasonable particle size to reduce pressure in the filtration section

Strong wear resistance, good fluidity, less fine powder during operation, and relief of filtration blockage

High chemical stability, suitable for a wide pH range, and the carrier is not easily detached

Large specific surface area and good anti toxicity
