CONTINUOUS METHOD FOR THE PRODUCTION OF NEOPENTYL GLYCOL |
摘要 |
<p>A continuous method for preparing neopentyl glycol by addition of isobutyraldehyde and formaldehyde in the presence of a tertiary alkylamine as catalyst to give hydroxypivalaldehyde with subsequent hydrogenation in the gas phase at a temperature of 125 to 180° C., is characterised in that the hydrogenation is carried out in the presence of a copper chromite catalyst comprising the activators barium and manganese and at a superatmospheric pressure of 30 to 120 kPa.</p> |
