Isooctyl palmitate preparation system with dehydration function

Abstract

The invention relates to an isooctyl palmitate preparation system with a dehydration function. The system comprises a reaction tower, wherein a steam discharge pipe, an isooctanol recovery tube and apalmitic acid inlet are connected at the top of the reaction tower; the steam discharge pipe is connected with an isooctanol receiving pot; the isooctanol receiving pot is connected with a No.1 oil-water separator; an oil outlet of the No.1 oil-water separator is connected with the isooctanol recovery tube; a water outlet of the No.1 oil-water separator is connected with a No.1 water receiving pot; an isooctanol and catalyst inlet is connected on the side surface of the reaction tower; a discharge hole of the reaction tower is connected with a No.2 oil-water separator; a finished product outlet of the No.2 oil-water separator is communicated with a finished product heating pot; the other outlet of the No.2 oil-water separator is connected with a catalyst recovery pot; a dehydration deviceis connected with the finished product heating pot. According to the preparation system, isooctyl palmitate can be prepared efficiently and rapidly, so that the preparation efficiency is improved; meanwhile, the preparation system has the dehydration function, so that the quality and purity of a product are improved, and the production cost is lowered.

Description

technical field [0001] The invention relates to the field of packaging equipment, in particular to a system for preparing isooctyl palmitate with dehydration function. Background technique [0002] Isooctyl palmitate has good permeability, antiperspirant effect, and strong affinity with skin. It is a dry and breathable oil. It is widely used in skin care products and cosmetics. It is an excellent skin emollient with stable performance and is not easy to oxidize or produce Odor, can make the skin soft and smooth without greasy feeling, good permeability, commonly used in various skin creams. [0003] The traditional preparation method of isooctyl palmitate uses the product of esterification reaction between palmitic acid and isooctyl alcohol, but a large amount of water will be produced during the esterification reaction, and the high water content usually reaches 35%-45%. It will seriously affect the quality of the prepared isooctyl palmitate, and it needs to be dehydrated....

[0003] The traditional preparation method of isooctyl palmitate uses the product of esterification reaction between palmitic acid and isooctyl alcohol, but a large amount of water will be produced during the esterification reaction, and the high water content usually reaches 35%-45%. It will seriously affect the quality of the prepared isooctyl palmitate, and it needs to be dehydrated. There are two methods generally used now: the first, distillation, to remove the moisture in the product by distillation; the second, add water to remove The water agent is then separated and recovered; the process of the above two methods is complicated, the production efficiency is low, and there will be water agent left in the product, which reduces the quality of the product. During the distillation process, additional distillation equipment needs to be added at a high cost
