Abstract:
A method for efficiently producing t-butanol as a raw material of a methacrylic resin from isobutanol is described, including a step (1) of dehydrating isobutanol to obtain butenes, and a step (2) of hydrating the butenes to obtain t-butanol. A method for producing methacrolein and methacrylic acid is also described, which further includes a step (3) of dehydrating and oxidizing the obtained t-butanol to obtain methacrolein and methacrylic acid. An apparatus for performing the steps (1) to (3) is also described.
