S. Bal et al., EXTRACTION OF OXIDIZABLE COMPOUNDS FROM W ASTE ACIDS AFTER BENZENE SULFONYL CHLORIDE PRODUCTION, Przemysl Chemiczny, 73(11), 1994, pp. 435-436
This paper describes a method of oxidizable compounds removal, especia
lly benzenesulfonic acid, from the liquid waste generated in the produ
ction of benzene sulfonyl chloride. It was found out that the oxidizab
le compounds content in the liquid waste was reduced substantially by
extraction with 2-ethylhexanol. A process now sheet with solvent recyc
ling system is proposed.
