Technical Document

Crude Sulphate Turpentine (CST) is a by-product of the Kraft pulping process, obtained by treating crude turpentine with sulphuric acid. CST is a complex mixture of modified terpene compounds formed through acid-catalyzed reactions. It serves as a raw material for producing various specialty chemicals and refined turpentine derivatives. CST is typically supplied in liquid form, with a color ranging from amber to dark brown, and it exhibits a viscous, resinous texture.
