| titleOfInvention | Separation and recovery method of propargyl alcohol |
| abstract | (57) [PROBLEMS] To solve the problems of the prior art, and to separate and recover the propargyl alcohol from a product mixture containing a solvent, water and propargyl alcohol, to increase the size of a distillation apparatus, to perform a separation operation or a process. The present invention provides a method for separating and recovering propargyl alcohol by a simple operation and advantageously in terms of thermal energy without complicating the process. The method for separating and recovering propargyl alcohol according to the present invention comprises the steps of: producing a product mixture containing propargyl alcohol obtained by reacting paraformaldehyde and acetylene in a polar solvent in the presence of a catalyst; Distillation is performed under the condition of mmHg. |
