Tertiary carbonic acid, also known as new acid or trialkylacetic acid, is a kind of branched monounsaturated carboxylic acid and an important branch of industrial fatty acids. Tertiary carbonates have excellent hydrolysis resistance, in addition to high heat resistance, weather resistance, color change resistance and other properties. Therefore, it is widely used in medicine, coatings, pesticides and many other fields.
A chemical plant in Henan Province uses low-pressure carbonyl method to synthesize tertiary carbonic acid. The reaction conditions are mild and the reaction yield is high. However, the separation of catalyst and product is difficult, the consumption of sulfuric acid is large and the pollution is serious. Therefore, it is necessary to optimize the production process of tertiary carbonic acid.
After investigation, this chemical plant finally cooperated with Tiei to adopt CWL-M centrifugal extraction equipment to realize the effective separation of catalyst and product, and better optimize the product washing and other process sections.
