Iso-octyl palmitate cycle production processing system

Abstract

The invention discloses an iso-octyl palmitate cycle production processing system comprising a reaction tank, an isooctanol storage tank and a palmitic acid storage tank, wherein the isooctanol storage tank and the palmitic acid storage tank are respectively arranged on two sides above the reaction tank, and the isooctanol storage tank and the palmitic acid storage tank are respectively connectedwith the reaction tank by a connecting pipe; a liquid output pipe is arranged under the reaction tank, the liquid output pipe is connected to the reaction tank and a distillation tank, a heating jacket is wrapped on the outer wall of the distillation tank, the distillation tank is further provided with a steam output pipe, the steam output pipe is connected with an isooctanol recovery tank, the steam output pipe is provided with a condensation section, the isooctanol recovery tank and the reaction tank are connected by an isooctanol recovery pipe, and the isooctanol recovery pipe is also provided with a transfer pump. By adopting the structure, raw materials contained in a finished product are effectively recovered, the raw materials can be fully utilized, the waste of the raw materials isreduced, the quality of the products is improved, and the harm of the raw materials to the environment and the human body is avoided.

Description

technical field [0001] The invention relates to the field of chemical production and processing equipment, in particular to a circulation production and processing system of isooctyl palmitate. Background technique [0002] The processing of isooctyl palmitate mainly relies on the esterification reaction of palmitic acid and isooctyl alcohol. Since the addition of the two raw materials cannot be precisely controlled, the finished product of isooctyl palmitate usually contains a certain amount of palmitic acid and Isooctyl alcohol raw materials, these raw materials lead to the impurity of the product and have a certain impact on product quality, especially isooctyl ester, which is a toxic substance with a special smell. The existing distillation method can easily lead to its leakage, causing damage to the product. Environmental pollution and bodily injury of workshop staff. Contents of the invention [0003] The technical problem to be solved by this invention is to provid...
