Differentiation titration using p-toluenesulfonic acid was carried out on a mixture of primary, secondary, and tertiary amines. It was found in a titration of a mixture containing two kinds of amines that a simple fnnctional relationship existed between the calculated value y and titrated value x of quantitative ratio of the amines expressed as y=a+bx. By the use of this relative equation, two kinds of amines can be separatory determined with good accuracy.
