Problems solved by technology
[0003] The traditional preparation method of isooctyl palmitate uses the product of esterification reaction between palmitic acid and isooctyl alcohol, but isooctyl alcohol remains in the product during the esterification process, and isooctyl alcohol will cause the product to emit peculiar smell. The method of octanol is distillation, but there are certain defects in the distillation method, which seriously affects the quality of the product, resulting in a narrower range of use

The invention relates to a device for preparing isooctyl palmitate with the effect of removing alcohol, which comprises a reaction tower, and the top of the reaction tower is connected with an exhaust pipe, an isooctyl alcohol recovery pipe and a palmitic acid inlet, and the exhaust pipe is connected with The isooctyl alcohol receiving tank, the isooctyl alcohol receiving tank is connected to the No. 1 oil-water separator, the side of the reaction tower is connected with isooctyl alcohol and the catalyst inlet, and the discharge port of the reaction tower is connected to the No. 2 oil-water separator. The finished product outlet of the No. 2 oil-water separator is connected with the finished product heating tank, and the other outlet of the No. 2 oil-water separator is connected with the catalyst recovery tank, and the catalyst recovery tank is connected with the isooctyl alcohol and the catalyst inlet through the No. 1 pump; the heat exchange There is an alcohol removal device connected to the device. This preparation system can efficiently and quickly prepare isooctyl palmitate, improve its preparation efficiency, and at the same time have the function of removing alcohol, thereby improving product quality and purity, and reducing production costs.
Description
Technical field [0001] The invention relates to the field of packaging equipment, in particular to a preparation device of isooctyl palmitate with the effect of removing alcohol. Background technique [0002] Isooctyl palmitate, good permeability, antiperspirant effect, strong affinity with the skin, is a dry breathable oil, widely used in skin care products and cosmetics, is an excellent skin softener, its performance is stable, not easy to oxidize or produce The peculiar smell can make the skin soft and smooth without greasy feeling. It has good permeability and is often used in various skin creams. [0003] The traditional preparation method of isooctyl palmitate uses palmitic acid and isooctyl alcohol to carry out the esterification reaction product, but in the esterification reaction process, there is isooctyl alcohol remaining in the product, and isooctyl alcohol will cause the product to emit peculiar smell. The method of octanol is distillation, but the distillation method...
