Abstract
The presently claimed invention relates to a process for the recovery of 3-methyl-3-buten-1-ol from a stream obtained in the production of 3-methyl-3-buten-1-ol from 2-methylprop-1-ene and formaldehyde, by treating the stream with an amine catalyst.
Claims16
A process for recovery of 3-methyl-but-3-en-1-ol from a stream comprising 3-methyl-but-3-en-1-yl formate, ≥0.01 wt. % to ≤10 wt. % water and ≥50 wt. % to <70 wt. % methanol, each based on the total weight of the stream, comprising at least the steps of:
- contacting at least one amine catalyst with the stream to obtain a treated stream;
- A) subjecting the treated stream to a temperature in the range of ≥40° C. to ≤120° C. to obtain 3-methyl-but-3-en-1-ol;
- and
- B) removing 3-methyl-but-3-en-1-ol from the treated stream.
