Produktbeschreibung
Excerpt from Commercial Organic Analysis, Vol. 1: A Treatise on the Properties, Proximate Analytical Examination, and Modes of Assaying the Various Organic Chemicals and Products Employed in the Arts, Manufactures, Medicine With Concise Methods for the Detection and Determination of Their Impurities, Adu The last edition of this volume, issued in 1885, and which had been out of print for several years, was recently reprinted, under the date of 1898, without the permission of the author and without revisions; and as this unauthorized reprint necessarily misrepresented Mr. Allen´s present views on many subjects, he determined to issue a revised edition immediately. While everything has been done to make the book up to date, the exigencies of the occasion limited the time that could be allotted for revision, and distance prevented submission of any manuscript or proof-sheets to the author. Mr. Allen has furnished material, written and printed, on the following subjects: Kjeldahl process; proteids of wheat-flour; vinegar; brewing sugars; malt-substitutes; hop-substitutes; secondary constituents in spirits. Information on the following topics has been added by the American revisor, partly from suggestions furnished by Mr. Allen: Specific gravity; formaldehyde; vinegar; methyl alcohol; acetone; fusel oil; argol; starch; glucose; invert sugar; lactose; wine; and brief notes on other topics. Processes of the American Association of Official Agricultural Chemists have been reprinted from "Bulletin 46" (now out of print), and the revisionary supplements. Numerous typographic errors have been corrected, and the index has been much enlarged. The revision of Vol. II will be much more extensive than that of Vol. I, and is now considerably advanced. I propose to devote a Third Volume to the consideration of Nitrogenised Organic Substances, including Cyanogen Compounds, Alkaloids and Organic Bases, Albuminoids, &c., and hope to have this ready for the press by the time Volume II. appears. I believe that this rearrangement of subject-matter will render the book more convenient for reference, while adapting each particular volume to the special requirements of certain users. I take this opportunity of thanking collectively the considerable number of Chemists, many of whom are personally unknown to me, who have given me the benefit of their special experience, and by whose assistance the book has greatly profited. I am also largely indebted to many Scientific and Technical Journals, and to certain kindred works dealing with Proximate Organic Analysis, for much of the information incorporated in the new edition.
