a high molecular weight, oil soluble secondary amine supplied as a
liquid in the Free-Base form. The high molecular weight and
structural configuration impart excellent solubility in most common
organic solvents and extremely low solubility in aqueous solutions.
characteristics, together with the ability of secondary amines to
react with acids to form the corresponding amine salts, make
possible the removal of acidic constituents from an aqueous
solution. Furthermore, the anions which are associated with the
amine salt in the organic phase are free to enter into an exchange
reaction with other anions in an aqueous solution to form a new,
oil-soluble but water-insoluble amine salt.
