| titleOfInvention | Recovery method of alkyl vinyl ether |
| abstract | PROBLEM TO BE SOLVED: To provide an alkyl vinyl ether and a glycol ether as a raw material and a collector from a gaseous reaction mixture obtained by subjecting a glycol ether to an intramolecular dehydration reaction in a gas phase. Efficient collection, A method for purification and recovery is provided. SOLUTION: A gaseous reaction mixture is liquefied and collected using glycol ethers as raw materials as a collecting agent. The obtained collected liquid is continuously distilled using the continuous distillation column 2 to distill a distillate containing alkyl vinyl ether and water, while distilling a bottom liquid containing glycol ethers. The distillate is allowed to stand in the separation tank 3 and separated into an oil layer and an aqueous layer, thereby recovering the alkyl vinyl ether as the oil layer. On the other hand, when the bottoms contain water, the bottoms are continuously distilled with an azeotropic agent using a continuous distillation column, and a distillate containing an azeotropic composition of water and an azeotropic agent To recover glycol ethers as bottoms. |
