Abstract

An olefin hydration reaction method comprises the following steps: respectively introducing water and a mixed C4 raw material into a reactor, mixing and contacting with a solid acid catalyst, and carrying out hydration reaction under hydration reaction conditions to obtain tert-butyl alcohol; wherein the olefin hydration reaction device consists of a reactor (5), a liquid-solid separator (10), a liquid-liquid separator (15) and a jet mixer (4); a dispersed phase inlet (1) and a continuous phase inlet are formed in the bottom of the reactor, and the top of the reactor is communicated with the bottom of the reactor sequentially through a downcomer upper section (9), a solid-liquid separator, a downcomer lower section (11) and the jet mixer (4). The clear liquid outlet (12) of the solid-liquid separator is communicated with an inlet of the liquid-liquid separator, and a water phase outlet of the liquid-liquid separator is communicated with a suction inlet of the jet mixer (4). According to the olefin hydration reaction method provided by the invention, liquid-liquid mass transfer is enhanced, the catalyst circularly flows in the reactor, the reaction efficiency can be improved, and the long-period operation of the device is realized.

Description

technical field

[0001] The present invention relates to a kind of equipment and method for preparing tert-butanol, more specifically, a kind of equipment and corresponding method for preparing tert-butanol with solid acid as catalyst, isobutene and deionized water in C4 mixture as raw materials.

[0002] technical background

[0003] As an important chemical product, tert-butanol (TBA) is mainly used as a solvent and an intermediate for the preparation of methyl methacrylate, tert-butylphenol, tert-butylamine and other compounds, and can also be used as an intermediate for the purification of isobutylene from carbon-four mixtures body. The industrial synthesis of tert-butanol is mainly obtained through the addition reaction of water and isobutene under the action of acid. Among them, the liquid sulfuric acid method has been gradually replaced by the solid resin method due to serious corrosion and low product purity. However, because water and carbon four are immiscible syst...
