NOVEL ETHYNYLATION CATALYST AND METHOD OF MAKING SAME |
| 摘要 |
A novel catalyst useful in the ethynylation of formaldehyde to butynediol is formed by precipitating copper and bismuth from a salt solution of such metals, utilizing an alkali metal hydroxide as the precipitating agent to deposit copper and bismuth hydroxide as a coating around a siliceous carrier particle. |

1. A method of preparing a catalyst for the ethynylation of formaldehyde which comprises: depositing by precipitation copper hydroxide via the reaction of an acidic copper salt solution with an alkaline metal hydroxide, on a particulate siliceous carrier, and calcining the treated carrier to yield a copper oxide coating around said particulate siliceous carrier. |
