EXPERIMENTAL METHODS IN CATALYTIC RESEARCH Volumes 2 and 3 edited by ROBERT B. ANDERSON and PETER T. DAWSON Volumes in the PHYSICAL
CHEMISTRY
Series
From the Preface: Since 1935 the experimental methods used in catalytic r e search have increased both in number and complexity, so that mastery of all of the techniques available is difficult. Volumes 2 and 3 provide useful accounts of these methods written by specialists. As in Volume 1, each chapter includes a description of the method and its fundamental principles, the apparatus used, the data obtained and their interpretation, and finally an account of special problems related to catalytic research. Volume 2 considers the preparation and examination of practical catalysts, and Volume 3 the characterization of surfaces and adsorbed species.. . .

INDICATING DRIERITE changes from blue when dry to rose-red when exhausted Indicating DRIERITE is a chemical drying agent for the efficient and rapid drying of air and gases in systems where visual indication of active desiccant is desired. In use, the color changes sharply to a rose-red as the margin between the exhausted and active desiccant progresses through the tube or column. It is available in 8 Mesh, the standard granule size, and in 20-40, 10-20, 6 and 4 Mesh. Impregnated with cobalt chloride, Indicating DRIERITE retains the high efficiency of Regular DRIERITE, anhydrous calcium sulfate, plus the added advantage of the color change for indication. It dries air and gases to a terminal dryness of 0.005 milligram per liter of gas.
ANNUAL REPORTS ON NMR SPECTROSCOPY, Volume 6B edited by E. F. MOONEY Annual Reports on NMR Spectroscopy has established itself as a means for the specialist and non-specialist alike to become familiar with new applications of the technique in all branches of chemistry, including biochemistry, and pharmaceutics, and the series will continue to be a valuable source of information for all analytical structural and physical chemists.

Regeneration reverses the color change and makes possible repeated use after heating at 375-450°F while spread one granule deep for one hour. Regular white DRIERITE (non-indicating) is available in the above mentioned sizes and also in 200 Mesh and 325 Mesh. DRIERITE is a product of W. A. Hammond Drierite Co., Xenia, Ohio.
