Abstract
IN the United States, the older cruder methods of refining are fast becoming obsolete and are being everywhere replaced by solvent processes, which have the great merit of removing the unsatisfactory asphaltic constituents generally termed naphthenics. In addition, the systematic use of additives for improving certain particular characteristics is beginning to become of commercial importance. The time is ripe for the description and discussion of these new methods of refining and the general principles which underlie them: it is now provided in handy book form by Mr. V. A. Kalichevsky, as one of the well-known American Chemical Society series of monographs.
