What is the equivalent weight of CH3COOH

The chemical auxiliaries in the textile finishing industry

Summary

The main acids used in the textile finishing industry are: sulfuric acid, hydrochloric acid, sulfurous acid, acetic acid, formic acid, oxalic acid, tartaric acid, lactic acid and citric acid. They are used for a wide variety of purposes and for a wide variety of fibers, and the acid used can often be replaced by other acids. In many cases it is only the price of the material that counts; the question is then a purely economic one. In other cases it is difficult or impossible to replace an acid with another acid; this applies when it is a question of the specific and not just the acidic properties of an acid. It is therefore necessary to distinguish the acidic from the specific use effect. Apart from the respective concentration, the first is directly dependent on the molecular size or the equivalent weight, the second on the specific properties of the chemical compound. In the vast majority of cases, both usage effects come into play at the same time, although one or the other is usually in the foreground. Is it only about the acidic use effect, z. B. when neutralizing an alkali, the price question is decisive.

Notes

Special hint

This chapter is part of the Springer Book Archives digitization project with publications that have appeared since the publisher's inception in 1842. With this archive, the publisher provides sources for both historical and disciplinary research, each of which must be viewed in a historical context. This chapter is from a book that was published before 1945 and is therefore not advertised by the publisher in its political-ideological orientation typical of the time.
