    Abstract: A device for continuously manufacturing acrylate compound and a method for continuously manufacturing acrylate compound are provided. The device for continuously manufacturing acrylate compound includes a reaction system, a feed tank and a collection tank. The feed tank connects to the inlet port of the reaction system, in order to introduce an alcohol compound and acrylic acid compound into the reaction system. The collection tank connects to the outlet port of the reaction system, in order to collect the acrylate compound. In particular, the reaction system includes at least two reaction units, an inlet port and an outlet port, wherein each reaction unit includes a microreactor and a centrifugal element.

    Abstract: A method for preparing a nitrate ester is provided. The method includes providing a first solution including a compound (which has at least one hydroxyl group) and a carboxylic acid having 2-5 carbon atoms; providing a second solution including nitric acid, acetic anhydride, and acetic acid; and transferring the first solution and the second solution to a microreactor, obtaining a nitrate ester after a residence time. In particular, the ratio of the weight of nitric acid to the total volume of the acetic anhydride and acetic acid is 1:1 to 1:3.5. The ratio of the molar amount of nitric acid to the hydroxyl group equivalent of the compound is from 1:1 to 15:1.
