Abstract:
1. A method of preparing a glycol mono-tertiary-butyl ether compound, the method comprising: a catalytic reaction step for preparing a glycol mono-tertiary-butyl ether compound and a glycol di-tertiary-butyl ether compound as a byproduct by reaction between a glycol compound and a C a byproduct extraction step for separating the glycol mono-tertiary-butyl ether compound and the glycol di-tertiary-butyl ether compound, prepared in the catalytic reaction step, using a hydrophilic extractant and a lipophilic extractant; and a byproduct decomposition and recycling step for decomposing the separated glycol di-tertiary-butyl ether compound into a glycol compound and isobutene and recycling the decomposed glycol compound and isobutene as the reactants to the catalytic reaction step.
