PREFACE. THE need of a book of reference giving brief descrip- tions of the various chemicals and other substances which are employed in the paint, colour and varnish trades has been expressed to me by many correspon- dents. In the following pages I have endeavoured to satisfy that need with, I hope, some small measure of success. As regards the methods of manufacture pf pigments like white lead, vermilion, chrome yellow, Prussian blue, etc., I have only briefly referred to them, and for fuller details I would refer readers to my Manual of Painters Colours, Oils and Varnishes, in which they will find them fully described. In my book on Soaps will be found an extended account of the chemistry of oils, and a full account of the methods of extraction, and to this book reference may usefully be made. Although the coal tar colours have come to the front of late years for the preparation of lake pigments, only a brief reference to them has been made their number is now so great that it was quite impossible to note them in detail. Any one interested in them will find a detailed account in my Dictionary of Coal Tar Colours. CHEMICAL LABORATORY, 22 BLACKFRIARS STREET, SALFORD. March, 1901. GEORGE H. HURST. CONTENTS.

ACETATES, A series of compounds derived from acetic acid by combination with metallic or other bases. Many acetates are valuable industrial compounds. They are gener- ally soluble in water a few containing basic oxides, such as those of copper and iron, are insoluble in water. When heated with dilute sulphuric acid they are decomposed and acetic acid is given off, with the formation of a sulphate of the base. The following acetates are those most used in the colour industry ACETATE OF AMMONIA The normal salt has the formula NH iC2H 3O it is mostly sold in the form of a solution in water, and is conveniently made by mixing the ordinary liquor ammonia with acetic acid. If glacial acetic acid be employed with the strong liquor ammonia, about equal volumes are required a solution of acetate of ammonia so prepared has a specific gravity of 1110. Acetate of ammonia may be obtained in the solid state, but as acetate of ammonia on heating readily passes into acetamide, C 2H aONH 2, the solid often contains that product. Acetate of ammonia is easily soluble in alcohol. The com- mercial article may be adulterated by addition of chloride or carbonate or sulphate of ammonia. These may be readily detected by the ordinary tests for chlorides, carbonates or ACETATES OF LEAD. sulphates. Acetate of ammonia should completely volatilise on heating. The proportion of real acetate of ammonia in a com- mercial product is best ascertained by determining both the acetic acid and ammonia by distillation with sulphuric acid and with caustic soda, as described under Acetic Acid and Ammonia. ACETATES OF LEAD...

We see application of science everywhere. Whether we are aware or not, science application plays a big part in our daily lives. While you are reading this page, an important element of optical science is in use. Electricity, for example, is one of the most important science discoveries ever made. As we walk in the public, we see almost everyone carrying a cellular phone. This is an application of electronics & communications technology. To remain healthy, we use medicines, which is a specialised form of biology. It is only the knowledge of science which enables us to understand the life processes around us.V&S Publishers has brought for you dictionaries of terms in science, physics, chemistry and biology to make science simpler for you. The terms have been arranged alphabetically for quick reference. Suitable explanations of terms that have come into public domain recently also find mention. The standard of explanation has been kept at a level of understanding expected from an average secondary and senior secondary student. Illustrations and examples, at appropriate places, have been given. Readers who have not made a special study of any science subject will have also be able to grasp the definitions. Important scientific charts, tables, constants, conversion tables, etc., have been included as appendices to make this dictionary more useful. A glossary of Nobel Prize winners and their contributions is an added attraction.
Products, raw materials, and feedstocks are included, though to afarlesser extent;
only thoseupon which major industries are based, such as crude oil, natural gas,
minerals, and ores, are included. The full details of chemicals and their ...
