Alkaline Waste of caprolactam process
Alkaline waste of caprolactam production represents a water solution of sodium salts of acid by-products of a cyclohexane air oxidation
Application: Alkaline waste of caprolactam production is used in the construction industry as a plasticizer and air entrainer additive to concrete, reinforced concrete, mortar etc.; in manufacture of cement, porcelain, expanded clay gravel, bricks as well as gypsum, binding, refractory materials; to liquefy feedstock mixtures of clinker mineralization, to treat coal, ore and sand against frosting and dusting, etc; in oil production to increase oil yield of the oil pools.
