Abstract
A method for producing isobutyl vinyl ether using isobutyl alcohol as a raw material alcohol, the method including reacting the isobutyl alcohol with acetylene to obtain a mixture containing unreacted isobutyl alcohol and isobutyl vinyl ether, reacting the unreacted isobutyl alcohol and the isobutyl vinyl ether in the mixture in a presence of an acid catalyst to be converted into acetaldehyde diisobutyl acetal, and removing the acetaldehyde diisobutyl acetal by distillation.

A method for producing isobutyl vinyl ether using isobutyl alcohol as a raw material alcohol, the method comprising:
- reacting the isobutyl alcohol with acetylene to obtain a mixture containing unreacted isobutyl alcohol and isobutyl vinyl ether;
- reacting the unreacted isobutyl alcohol and the isobutyl vinyl ether in the mixture in a presence of an acid catalyst to be converted into acetaldehyde diisobutyl acetal;
- performing a treatment selected from the group consisting of neutralization of the acid catalyst and removal of the acid catalyst;
- and
- removing the acetaldehyde diisobutyl acetal by distillation.
A method for purifying isobutyl vinyl ether from a mixture containing isobutyl alcohol and isobutyl vinyl ether, the method comprising:
- reacting the isobutyl alcohol and isobutyl vinyl ether in the mixture in a presence of an acid catalyst to be converted into acetaldehyde diisobutyl acetal;
- and
