The use of a mixture of equal parts «-butyl alcohol and ethyl acetate has been shown by test analyses to be satisfactory for (1) the extraction separation of potassium and sodium perchlorates, two extractions with intermediate solution of potassium perchlorate being required; (2) the extraction separation of potassium and lithium perchlorates, one extraction only being required; and (3) the separation of sodium and lithium subsequent to their extraction from potassium, following the procedure of Willard and Smith 2 in which sodium chloride is precipitated from solution in nbutyl alcohol, by a hydrogen chloride solution in the same solvent. The sodium was determined volumetrically by Mohr's method. © 1925, American Chemical Society. All rights reserved.
