Abstract

The present invention discloses a continuous esterification micro-reaction apparatus and a micro-reaction system composed of the same. The continuous esterification micro-reaction apparatus is provided with a reaction chamber, a raw material inlet, a product outlet, a water outlet and a water permeable membrane. The water permeable membrane divides the reaction chamber into two parts, wherein a first part of the reaction chamber is communicated with the raw material inlet and the product outlet, the second part of the reaction chamber is communicated with the water outlet, and the spacing between the water permeable membrane and an inner wall of the first part, communicated with the raw material inlet and the product outlet, of the reaction chamber is 50[mu]m-2mm. The continuous esterification micro-reaction apparatus provided by the present invention is applied to a reactor for generating water. The water in the reaction can be removed from the reaction system so that the reaction is further carried out, thereby improving productivity, increasing product purity, and reducing waste discharge and post-processing cost.

Description

technical field [0001] The invention relates to a continuous esterification micro-reaction device and a micro-reaction system composed thereof, belonging to the technical field of chemical equipment. Background technique [0002] Membrane chemical reactor, that is, a reaction device or system composed of a membrane and a chemical reaction process, aims to realize the in-situ separation of products, the control input of reactants, the coupling of reactions and reactions, and the interphase transfer through the special functions of membranes. Intensification, reaction separation process integration, etc., to increase reaction conversion rate, improve reaction selectivity, reaction rate [0003] At present, the relevant research on membrane chemical reactors is mainly focused on improving the performance of membrane materials, separation coefficient, thermal permeability, structural stability, and other aspects. Because in order to fully carry out the reaction, the current con...
