Description:This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 Excerpt: ... UNIVERSITY' lUFf. INTRODUCTION. Nearly all the ordinary poisons and drugs may be arranged in three groups. This classification, based upon the chemical behavior of these substances during isolation from mixtures for identification, is as follows: Group I. This group includes volatile substances which distil undecomposed from an acid solution with steam. Yellow phosphorus, hydrocyanic acid, carbolic acid, chloroform, iodoform, aniline, nitrobenzene, carbon disulphide, etc., are the principal members of this group. Group II. This group includes non-volatile, organic substances, which do not distil from an acid solution with steam. They may be extracted, however, from extraneous matter with hot alcohol containing tartaric acid. Alkaloids, many glucosides and bitter principles, as well as certain synthetic organic drugs like acetanilide, phenacetine, antipyrine, pyramidone, sulphonal, etc., are comprised in this group. Group III. This group includes all poisonous metals. Accordingly, in toxicological analysis poisons are divided into three groups, each having its own special method of procedure. A few poisons like mineral acids, caustic alkalies, oxalic acid and potassium chlorate cannot be placed conveniently in these three groups, owing to differences in solubility and other peculiarities. Special tests for such substances must be made with a separate portion of material. Chapter IV contains a description of the methods used in identifying these substances. The material must be uniformly mixed and divided into three or four approximately equal portions, unless the analysis is to be limited to the detection of a single, well-defined substance. One portion is tested for non-volatile, organic substances (Chapter II). The second portion is examined for volatile ...We have made it easy for you to find a PDF Ebooks without any digging.
