A REDOX POTENTIAL MEASURER FOR USE IN REGENERATING CATALYST IN THE PRODUCTION OF ACETALDEHYDE |
| 摘要 |
<p>The process is used to regenerate the contact liquid which is used in the production of acetaldehyde from acetylene by mercury-catalysed addition of water. The spent contact liquid is treated at between 90 and 150 DEG C with HNO3, the addition of the HNO3 being controlled by a redox potentiometer.</p> |
