Title:
METHOD FOR PRODUCING (2-METHOXYETHYL) VINYL ETHER, AND METHOD FOR REFINING (2-METHOXYETHYL) VINYL ETHER
Document Type and Number:
WIPO Patent Application WO/2022/168950
Kind Code:
A1
Abstract:
Provided is a method for producing a (2-methoxyethyl) vinyl ether at a high level of purity from 2-methoxyethanol and acetylene.　A method for producing a (2-methoxyethyl) vinyl ether that treats 2-methoxyethanol as a source material alcohol, and includes the following steps A1, A2, and A3.　(Step A1) A vinyl ether synthesis step in which 2-methoxyethanol and acetylene are reacted to obtain a mixture that includes unreacted 2-methoxyethanol and the (2-methoxyethyl) vinyl ether.　(Step A2) An acetalization step in which the unreacted 2-methoxyethanol and the (2-methoxyethyl) vinyl ether in the mixture are reacted in the presence of an acid catalyst and converted into acetaldehyde bis(2-methoxyethyl) acetal.　(Step A3) A distillation step in which distillation is used to remove the acetaldehyde bis(2-methoxyethyl) acetal from the acetal-including mixture that was obtained in step A2.
