On the separation of isobutyraldehyde and isobutanol
Thread Content
Hello everyone, when using Aspen to simulate isobutyraldehyde and isobutanol, it was found that only 4 trays are required. By using 6 trays, I can separate isobutyraldehyde with a purity of 99%. Could someone who has time calculate it? Please make sure it’s correct, thank you.
In terms of their boiling points at atmospheric pressure, isobutyraldehyde boils at 64°C while isobutanol boils at 107°C – there is a significant difference, so it seems that no azeotrope exists. It is estimated that a smaller number of theoretical plates is required.
