Inventors include Matsubara, Wataru; Miyata, Yasuyuki; Kamito, Ryo; Genta, Minoru; and Ito, Motofumi.
The application for the patent was published on October 30, 2026, under issue no. 44/2026.
Abstract: In the present invention, terephthalic acid is appropriately obtained from DMT while lowering energy consumption. This hydrolysis reaction system comprises: a reaction tank to which dimethyl terephthalate and water are supplied and in which the dimethyl terephthalate is hydrolyzed by the water to generate terephthalic acid and methanol; a discharge device for discharging a mixture of methanol and water from the reaction tank; and a control device for controlling the discharge system. The control device: does not discharge the mixture to the discharge device in a first period up to a first timing point after the dimethyl terephthalate and water are supplied to the reaction tank; discharges the mixture to the discharge device in a second period after the first timing point up to a second timing point that is after the first timing point; and does not discharge the mixture to the discharge device in a third period after the second timing point up to a point where terephthalic acid is derived from the reaction tank. The first period is shorter than the third period.
