Abstract

A production system of isooctyl palmitate, including an esterification reaction part and a purification part, often esterifies palmitic acid and isooctyl alcohol in a reaction tank, and fills nitrogen protection during the reaction, and most of the isooctyl alcohol will be It is extracted from the first condenser and the oil-water separator to obtain the crude product of isooctyl palmitate; then the crude product of isooctyl palmitate is pumped into the purification tank for vacuum distillation, and the excess water, cyclohexane and isooctyl alcohol to obtain the finished product of isooctyl palmitate; due to the use of nitrogen protection and steam heating, the reaction conditions are constant and the reaction time is controllable, and the product quality of isooctyl palmitate is good, clear and transparent; The isooctyl alcohol, cyclohexane and catalyst can be recycled to reduce the cost of the enterprise; the exhaust gas is filtered through the bubble tank to reduce environmental pollution.

Description

technical field [0001] The invention relates to a production system of isooctyl palmitate. Background technique [0002] Isooctyl palmitate is the product of the esterification reaction of palmitic acid and isooctyl alcohol. It needs to add catalyst and cyclohexane during production. The produced isooctyl palmitate will contain 2% to 50% of water, not The catalyst of the reaction, cycloethane and isooctyl alcohol, so the crude product of isooctyl palmitate needs to be purified before it can be used. Generally, the three-way azeotropic method and distillation are used for purification. This purification method not only requires a large investment in equipment, but also Complex, and the purity of the purified isooctyl palmitate is not high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a production system of isooctyl palmitate, which can generate high-purity isooctyl palmitate, has small investment in equipment,...
