Abstract: The present invention relates to an enhanced reaction system and process for propylene hydration catalyzed by an ionic liquid. The system comprises: a reactor, a micro-interface generator, a pre-heating device, etc. In the present invention, propylene gas is crushed to form micron-scale bubbles on a micrometer scale, with the micron-scale bubbles having physicochemical properties that conventional bubbles do not have. It can be seen from the calculation formulae of the sphere volume and the surface area that where the total volume is constant, the total surface area of a bubble is inversely proportional to the diameter of the single bubble. It can be seen therefrom that the total surface area of the micron-scale bubbles is huge, such that the micron-scale bubbles are mixed with the ionic liquid catalyst to form a gas-liquid emulsion, so as to increase the contact area between the two phases, i.e. the gas and liquid phases, and achieve the effect of enhancing the mass transfer within a lower preset operation condition range. In addition, the rate of conversion into propylene is further increased to a certain degree.
