A Theoretical and Practical Treatise on the Manufacture of Sulphuric Acid and Alkali, with the Collateral Branches

Abstract

THE publication of the third and concluding volume of Prof. Lunge's excellent work follows wonderfully soon on that of the first and second. This volume, which fully equals the other two in accuracy of description and clearness of style, is devoted to the subsidiary processes lying alongside of the main channel of Leblanc's great discovery. We first find a chapter on the ammoniacal soda process now rising, through Solvay's exertions, into well-merited and formidable competition with its older rival. The ash made by this theoretically beautifully simple and practically most original process is very pure, containing from 98 to 99 per cent, of Na₂CO₃, and free of course from the impurities common to Leblanc's ash of caustic soda and sulphide of sodium.

A Theoretical and Practical Treatise on the Manufacture of Sulphuric Acid and Alkali, with the Collateral Branches.

By George Lunge, Professor of Technical Chemistry at the Federal Polytechnic School, Zurich (formerly manager of the Tyne Alkali Works, South Shiells), Vol. III. (J. Van Voorst, 1880.)
