【Chinatungsten】Copper Phosphotungstate

Copper phosphotungstate is a product of reaction between phosphotungstic acid and copper nitrate, mainly used as catalyst for petrochemical oxidative desulfurization, catalytic synthesis of acetyl acetal, tetrahydrofuran, etc..

Copper phosphotungstate catalyzed a series of aldehydes and acetic anhydride synthesis of the corresponding acetyl acetal reaction. Result shows that formaldehyde and acetic anhydride substance ratio is 1:2. Copper phosphotungstate takes amount of aldehyde accounted for only 0.5% (molar ratio) the reaction can be completed in a relatively short period of time, the product yield of 62% to 96%. The catalyst in the presence of ketones and aldehydes at the same time, can selectively react with aldehyde.
