Magneto-optical rotation studies of liquid mixtures. Part 6.—Specific interactions in mixtures of CCl4 with aliphatic and aromatic ketones and esters
Abstract
Measurements have been made of the magneto-optical rotations at 435.8 nm of binary mixtures of CCl4 with 35 aliphatic and aromatic ketones and esters. The departure from ideality of each binary mixture was treated in terms of an excess magnetic rotation, αE; for many systems, particularly the aromatic compounds, the variation of αE with composition gave indications of interaction between the CCl4 and the other component. The results for the longer-chain aliphatic compounds indicated that their liquids contain orientational order which was broken up by addition of the CCl4. The molar magnetic rotations, Λm, were calculated from the results and compared with the values calculated from a set of partial magnetic rotation parameters obtained previously. In most cases the agreement was quite good thus confirming the approximate additivity of the Faraday effect.
