Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Electrochemical Analysis Section: Summary of Activities, July 1967 to June 1968 The Analytical Chemistry Division was established as a separate division at the National Bureau of Standards on September 1, 1963, and became part of the Institute for Materials Research in the February 1, 1964, reorganization. It consists at present of nine sections and about 100 tech nical personnel encompassing some 57 different analytical competences from activation analysis and atomic absorption to vacuum fusion and x-ray spectroscopy. These competences, and in turn the sections which they comprise, are charged with research at the forefront of analysis as well as aware ness of the practical sample, be it standard reference material or service analysis. In addition it is their responsibility to inform others of their efforts. Formal publication in scientific periodicals is a highly important output of our laboratories. In addition, however, it has been our experience that informal, annual summaries of progress describing efforts of the past year can be very valuable in disseminating information about our programs.

This book was released on 1968 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brief summaries of several lines of work under way are given. The review describes briefly new equipment and facilities acquired during the year. A major effort devoted to acidity measurements has led to new pH standards and new reference solutions for pD in heavy water. Solvent effects on acid-base phenomena in mixed solvents have shed some light on the factors, including solvent structure, governing ion-solvent interactions. A start was made on the study of ion-specific electrodes and the establishment of standard scales for ionic activity. Equilibrium data for hydrochloric acid in 92.41 wt. percent ethanol and for the ionization of carbonic acid in heavy water were obtained. The establishment of conductance standards for oceanographic research was begun. The survey concludes with lists of the members of the Section staff, publications and manuscripts produced during the year, talks given by the staff, and committee assignments. (Author).

This book was released on 1969 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes the research activities and scientific programs of the Microchemical Analysis Section of the Analytical Chemistry Division of the NBS Institute for Materials Research during the period July 1968 to June 1969. General activities are reported in the areas of gas analysis, polarography, potentiometry, coulometry, chemical microscopy, and classical microchemical analysis. Research activities described in some detail include: gravimetric preparation of gas analysis standards; polarographic determination of trace elements in glass; fabrication and performance of a microfluorine electrode; elucidation of the boric acid-borate-mannitol system; investigation of the relation between the equilibrium point and inflection point in acidimetric titrimetry; coulometric determination of trace quantities of chromium; and determiniation of trace elements by nuclear track measurements. A number of procedures which have been developed for the analysis of a variety of materials, utilizing the techniques mentioned above, are also included. (Author).

This book was released on 1967 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: An attempt is made to summarize a year's progress on the technical projects of the Section in such a way as to stress the program and capabilities of the organizational unit as a whole. A description of facilities and equipment is presented, and the directions of the programs are indicated. Brief summaries of several lines of work now under way are given. The main areas include the measurement of acidity, with progress toward the establishment of standards for pH, pH*, and pD being reported. Studies of the behavior of glass electrodes in deuterium oxide are described and solvent effects on ionic processes are discussed. Equilibrium data for certain ionic systems have been obtained, modifications of a precision conductance bridge are described, and a method for titrating hydrogen fluoride in dimethylformamide is outlined. The survey concludes with lists of the members of the Section staff, publications and manuscripts produced during the year, talks given by the staff, and committee assignments. (Author).

This book was released on 2013-10-22 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recommended Methods for Purification of Solvents and Tests for Impurities is a compilation of recommended procedures for purification of solvents and tests for solvent impurities. Ten solvents are covered: acetonitrile, sulfolane, propylene carbonate, dimethyl sulfoxide, dimethylformamide, hexamethylphosphoramide, pyridine, ethylenediamine, N-methylacetamide, and N-methylpropionamide. This book is comprised of 12 chapters and opens with an introduction to general aspects of impurity effects. The rationale for the selection of solvent is explained, and the relative reactivities of solutes in different solvents are described. The following chapters deal with dipolar aprotic solvents (acetonitrile, sulfolane, propylene carbonate, dimethyl sulfoxide, dimethylformamide, hexamethylphosphoramide, and pyridine) for which impurity effects can be particularly severe, along with their general properties (freezing and boiling temperatures, density, dynamic viscosity, refractive index, dipole moment, relative permittivity, etc.) and the typical chronology of improvements in purification procedures and tests for purity. The final three chapters focus on amphiprotic solvents (ethylenediamine, N-methylacetamide, and N-methylpropionamide). This monograph will be a useful resource for chemists.
