Production system capable of improving purity of iso-octyl palmitate

Abstract

A production system capable of improving the purity of isooctyl palmitate, comprising a reaction tank, a drying tower and a finished product collection tank, the top of the reaction tank is provided with a feed pipe and a first exhaust port, the reaction tank is provided with a stirring device, and the reaction tank There is a heating jacket on the side wall, and a discharge pipe is provided at the bottom of the reaction tank. The discharge pipe is divided into two branch pipes, one is connected with the feed pipe, and the other is connected with the feed port at the top of the drying tower. The discharge port at the bottom is connected with the finished product collecting tank. A branch pipe connecting the discharge pipe and the feed pipe is provided with a second conveying pump and a second valve. A branch pipe connecting the discharge pipe to the drying tower is provided with a first delivery pump and a first valve. A cooling device is also provided on a branch pipe connecting the discharge pipe with the drying tower. By adopting the above structure, the complete reaction of palmitic acid and isooctyl alcohol can be guaranteed, and the water produced by the esterification reaction can be effectively removed, so as to further improve the purity of isooctyl palmitate and improve product quality.

Description

technical field [0001] The invention relates to the production field of isooctyl palmitate, in particular to a production system capable of improving the purity of isooctyl palmitate. Background technique [0002] A large amount of water will be produced in the existing isooctyl palmitate production process, and the water produced cannot be completely removed, so it will have a certain impact on the quality of the final product, and isooctyl palmitate is produced through the reaction of palmitic acid and isooctyl alcohol Production, in actual production, the ratio of the two cannot be completely standardized, so a certain amount of unreacted palmitic acid or isooctyl alcohol must be mixed in the finished product, which will also affect the final quality of the product. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production system capable of improving the purity of isooctyl palmitate, which can ensure the co...
