A new process is described for the separation of mixtures of materials by multiplicative distribution, which is characterized by repeated addition of the mixture throughout the whole process and by material exchange during the countercurrent flow of finite amounts of one, and infinitesimally small amounts of the other phase. The intrinsic features of the mode of action of the old distribution processes and the new one are developed, and their relationship to one another is discussed. In this connection, an attempt is made to clarify the confused situation in the terminology of this field by introducing clearer definitions. Reflux and “displacement distribution”, another new distribution process, are treated briefly in two final sections.
