Method for separation and recovery of propargyl alcohol |
摘要 |
The present invention provides a method for separating and recovering propargyl alcohol from a product mixture containing a solvent, water and propargyl alcohol, which alleviates the problems of prior art and which can separate and recover propargyl alcohol in a simple operation at an advantageous thermal energy without requiring a large distillation unit or a complicated separation operation or step. The method for separation and recovery of propargyl alcohol according to the present invention is characterized by subjecting, to distillation at a pressure of 100 to 150 mmHg, a propargyl alcohol-containing product mixture obtained by reacting paraformaldehyde with acetylene in the presence of a catalyst in a polar solvent.
