Trialkylacetic acid, also known as tertiary carbonic acid or neoacid, is a type of branched monobasic saturated carboxylic acid and an important branch of industrial fatty acids. Tertiary carbonates have excellent hydrolysis resistance, and also have high heat resistance, weather resistance, and discoloration resistance. Therefore, they are widely used in many fields such as medicine, coatings, and pesticides. At present, the low-pressure carbonyl method is used to synthesize tertiary carbonic acid. The reaction conditions are mild, the reaction yield is high, and the operation is safer, but the separation of the catalyst and the product is difficult, the sulfuric acid consumption is large, and the pollution is serious. Therefore, it is very necessary to optimize the production process of tertiary carbonic acid.
With the development of science and technology, the extraction, separation and washing operation of trialkylacetic acid has also changed from the traditional method to a new process. At present, the advantages of the new process flow of trialkylacetic acid extraction are:
- The process is not limited to three-stage separation and water washing, and the number of extraction stages can be increased according to actual conditions.
- The process is suitable for separating organic matter that is immiscible with water.
- There is little residual liquid in the equipment after the equipment stops running.
- The process relies on centrifugal force for separation (several hundred to tens of thousands of times the gravity under the same conditions), and the separation efficiency is high.
- This set of process equipment occupies a small area, has low power consumption, and can realize the continuous production of tert-butyl carbonate.
The new process mainly relies on centrifugal extractors for operation. Centrifugal extractor is liquid-liquid extraction and separation equipment that has been widely used in recent years. They have gradually replaced traditional extraction equipment, especially in chemical water washing, alkali washing and acid washing units. Zhengzhou Tiei Extraction CWL-M series centrifugal extractor is an independently developed and produced extraction equipment, which is widely used in extraction operations in many industries such as chemical industry, hydrometallurgy, fine chemical industry, environmental protection, etc.
