Chemistry of the organic dyestuffs by Rudolf Nietzki

By Rudolf Nietzki

A bout 3 years in the past I wrote an editorial for Ladenburg s Handworterbuch der Chemie, containing in a concise shape an exhaustive account of the historical past of the natural Dyestuf Es. this text used to be additionally released individually and its solid reception brought about me to supply the current paintings, which i've got established so far as attainable upon the sooner one. the object in query was once no longer whole in itself, and within the current example yes sections which got here lower than different headings within the Handworterbuch were further. New fabric has additionally been provided during the advances made within the coal-tar color and in our medical wisdom of the structure of dyestuffs over the last 3 years. A achieve, a few matters were handled at a better size than was once accredited through the just a little restricted area of the Handworterbuch for that reason, the subject-matter of the sooner paintings has been submitted to a radical revision, and the systematic category of dyestuffs into common chemical teams tried within the unique e-book has been conducted in a extra whole demeanour, because of the advances made in our wisdom in their constitution.

Basic properties, yield on acetylation almost completely indifferent compounds. At any rate this fact strongly supports the assumption a certain linkage between the azo- and amido-groups. sulphoriic acids of the amidoazo-compounds are interesting in this respect. Apparently they are incapable of existing in the that there is The free state, at least from their colour it appears that the formation of a salt takes place between the sulpho-group and the basic group. Amidoazobenzene in the free state is yellow, while its sul- phonic acids have the red colour of the amidoazobenzene salts.

The salts of certain azosulphonic acids may be termed neutral They may be directly fixed on vegetable fibres. dyestuffs. v and acid dyestuffs are fixed without aid by animal basic Most fibres ; vegetable fibres, on the other hand, require the interven- tion of a special mordant. with basic dyestuffs, as it Tannic acid is forms insoluble generally used along salts with these com- pounds. Cotton possesses the power of attracting a certain amount of tannic acid from solutions containing this body, and of retaining even after washing.
