Preparation of ethynylbenzenes |
| abstract |
Ethynylbenzenes are prepared by the vapor phase catalytic dehydration of methyl phenyl ketones. The dehydration process is carried out at temperatures of from about 500 DEG to about 650 DEG C. using an alumina-containing catalyst. An example of the process is the dehydration of acetophenone to form phenylacetylene. |
