Separation of organic bases by Craig distribution. III. Development of a partition machine with variable lower phase volume and its use in the separation of amine mixtures

Abstract

cf. CA 60, 11427b. A new unit is described for use in the Craig extn. machine so that the vol. of the lower layer can be varied. The unit is used to sep. a mixt. of heptylamine, hexyl-, and heptylbenzylamine by using vol. ratios of 0.2-5.
